My crystal ball sees a bifurcation in the market at the $5000-$10,000 end of the market. There will be large sensor interchangeable lens cameras and as well as small 3 chip fixed lens cameras.

The large sensor cameras will serve markets in "planned" production. The small sensor 3 chip cameras will be geared towards run and gun shooting. Of course there's overlap

Daniel Caruso September 26th, 2010 07:48 PM

thanks guys, i dont remember where i found it. it was so great to see more of the camera and some talk about it.

i am really hoping the sony will be under 10 000, thats really pushing my funds haha, but if it is might be worth it to wait instead of the af100; ive saved all year and really want to make this purchase worthwhile. if its early 2011, details and price point im hoping will be out at least by november, but who knows.

keep the info coming if anyone finds out something =]

Alister Chapman September 27th, 2010 12:44 AM

I think the Sony 35mm camera shown at IBC will be at the higher end of affordable. Looking closely at it on the stand it was clearly constructed much more like a high end camera like the F35 than an EX. It looked to have an alloy outer body. There were lots of taped over holes and sockets. On the back there was some kind of door that was about the right size to cover two SxS slots. On the left side there is a rotary dial, this looks like the illuminated dial that the EX3 has, so I speculate that this is for frame rate control. The lens on the demo unit was a PL mount lens, but if you asked anyone from Sony they would not confirm that this is what the production unit would have. Interestingly on the top of the camera on the right side, where you would normally find the zoom rocker there was a large taped over hole about the size of a zoom rocker, so could there be planned provision of a zoom rocker? That would be unusual for a PL mount camera.
The word from Sony is that this camera will be out before NAB, possibly very early in the new year. I'm holding fire on any camera purchases until then as I think this will be the camera to get, however I fear it may be out of my price range, especially as I want two for 3D!

Paul Cronin September 27th, 2010 06:14 AM

Thanks Alister for the info. This is the camera Sony employees in NYC said would be under $50K. They did not say if it would be body only or what else was included.

I find examining the market as interesting as the technology. Given the above, Sony looks to make a competing camera to their F23 meanwhile major network shows examine the use of Canon 5D in their productions (as hobbled as HDSLR is for that function).

I do find it hard to believe (although not impossible) that Sony will cede the market to Panasonic and Canon in the lower budget professional price range. This is especially odd since Sony has the VG10 in the consumer market.

Paul Cronin September 27th, 2010 09:52 AM

Agree Craig it seems strange.

Andrew Stone October 17th, 2010 04:44 PM

I am kicking this thread as things are heating up with the immanent release of the AF-100/101 and there are lots of us who have been sitting on the sidelines waiting for more information on Sony's full sensor offering in the pro DOF market.

I noted earlier today that the AF100/101 will perform overcranking all the way up to 60 FPS using 1080p.

Sony's being really tight lipped about what there camera will offer. No word on pricing yet, no word on HD-SDI specs. I look at the body of the camera and it tells me it's about a 8 to 10,000 dollar camera but I see the viewfinder on the 3D camera. If that one lands on the 35mm one that could kick things up another 5 grand or more (up to 12 grand if it requires a pro viewfinder).

I can't see Sony loosing sales by holding onto key information for much longer. Does anyone have more info on the product?

Gabe Strong November 2nd, 2010 11:44 PM

Well, I don't know if this is a good place for this for sure, or if it should go in area 51, but there is
this about the new Sony:
Sony PMW-Ex35 HD Cinematography Camera with PL Mount and Full HD 35mm image sensor

John Vincent November 3rd, 2010 12:18 AM

Hmmmm..... Essentially a EX1 with a 35 mm sensor.... great news if true and would be a real threat to the Panny AF100 if it had interchangable lenses, which it would seem to have.

Oh, I love a good fight!

Brian Bang Jensen November 3rd, 2010 03:10 AM

At an estimated price of 12.500£ it is in my opinion no treat to the Panny AF100 at 3.400£.

Normally I do ENG type of work with my old and trusted F330, but next year I have some short film production coming up.
For that purpose I have been looking into buying a second camera.
As I am a one man band I have no economic room for several cameras at a price tag of more than 10.000£

The 35mm cameras is unusable for my normal work, whit their shallow dept of field.
For film production, SOME of the scenes would benefit from shallow dept op field.

The Panny is not what I am looking for, with its 8 bit SDI output and a sensor size making my Nikon FX lenses long.

If not something more suitable is coming up I think I will rather sell my 330 and buy a Sony PMW 350 and shoot the shallow dept of field scenes with some tele and iris wide open.

And no I will not go the DSLR way. With all its bit and pieces needed it will be as expensive as the new Sony and still have the moiré, aliasing and bad ergonomics.

It's worth thinking of exactly what the difference will be. The AF101 sensor will be very close to 4x the area of the 2/3" sensor of the PMW350. That will give it a 2 stop difference in terms of depth of field - you'll have to have the PMW350 opened up 2 stops relative to the AF101 for the same depth of field.

But - even the stock lens with the PMW350 is f1.9 (and on a 16x motorised zoom). Hence, for a any given angle of view, you'll need to get about f3.5 on the AF101 to match that, and at least f2.8 or more to substantially better it. That's certainly possible with some primes - but any sort of affordable zoom for that size of sensor is likely to be more like f4-5.6, and not have the benefits of motor zoom etc as well.

So if you go for the AF101, are you prepared to get a set of good fast primes? And accept a lot of lens changing on set? It's also worth pointing out that frequent lens changing with a digital sensored camera carries a risk that didn't exist when doing the same with film. That's dirt - get something behind the lens with film and it may be gone as the film moves on, or at worst give a hair in the gate for a shot or two. Potentially, it's likely to be far more difficult to get rid of with a digital sensor.

Brian Bang Jensen November 3rd, 2010 06:01 AM

Thanks for your comments David.

You are confirming me in what I have also figured out.
And on top of that have put some exact values on it.

Fist time I heard of the AF101, I thought.
“Hey here is an affordable film camera to go in, for film type of work, as my second, and on top of that I can use my Nikons”

The more information I get I can see this opportunity fading away, and that there is more business sense in getting a descend 2/3 camera instead.

On my initial thoughts I would have put my 24-70 and 70-200 f2.8 Nikon lenses in the front.
But as they will bee twice the focal length, it will leave me with no wide angle lens!!
Buying a set of primes is not an opportunity for me, and as you pointed out. It is a nightmare to change lenses all the time. Believe me, I have been there with DSLR.

As it looks from my point of view the PMW 350 looks like a winner as the multipurpose camera for my business.

Maybe the new Sony will fit someone who only goes the film way. But for me the solution will bee too expensive, considering the benefits I will get.

Lawrence Bansbach November 3rd, 2010 06:58 AM

Anything less than 10-bit from the HD-SDI and HDMI ports is just stupid. Panny made this mistake. The usual justification is "10-bit from the HD-SDI would make the camera more expensive," yet no one says how much. Would it be $10,000, $1,000, or $20 more?

Robin Davies-Rollinson November 3rd, 2010 07:00 AM

Another point worth considering when thinking about using a camera that will need frequent lens changes is the matter of back-focus. One might find that with all the changing, this might go adrift and will need appropriate adjusting...

Panasonic AG-AF100 Body: $4,999.00 at Vistek.ca

...My predictions for this mysterious "affordable" Sony 35mm sensor camera :

- Price: $20,000+

- Will not ship in 2011

I honestly feel that Sony was a little freaked-out by the announcement of the Panasonic AF-100 and had to cook-up something fast as a response.

...My predictions for the Panasonic AF-100:

- It will ship in quantity in the 1st quarter of 2011 ( though initial units will start trickling in at the end of Dec 2010 )

- It will be like the introduction of the HVX200 camera, and sell like hot-cakes in 2011 ( effectively owning this new large-sensor prosumer market for all of 2011 )

- The AF-100 will be a lot better than many people expect

Tim Polster November 3rd, 2010 03:27 PM

I think Sony will have a similar product to compete with the AF-100 from Panasonic. The community has known about the AF-100 since NAB and I would guess that industry people new about it long before that.

What would surprise me is if Sony did not have a model right around the corner given the NEX camera is already out there.

NAB this year will be quite interesting and I agree, the AF-100 will be a great tool. For me, I am waiting for a servo-driven model that can act more like a video camera if needed.

Andrew Stone November 3rd, 2010 04:14 PM

Hi Guy,

There are a lot of rumours going around right now particularly in the last couple of days about Sony's "new" products. I am not going to feed the rumour mill except to say that apparently Sony is going to have a public announcement later in November that will spell out more details about their "affordable" 35mm sensor camera and it is supposed to be less than 20 grand and THIS camera is suppose to be aimed at people in the Red market and it will have a PL mount. This is not their answer to the AF100/101. Info flying around beyond this is too far of an extrapolation from what Sony has already said about this 35mm sensored box and other cameras that they have not even mentioned in a public way.

I think it is safe to say the AF100/101 marketing has gone nuclear on the net. You sure have to hand it to Panasonic. They played the user input & viral marketing on this extremely well. I sure hope Sony is taking copious notes on this. Take a step off DVinfo and look around at the net buzz on the AF100. It is wild. A full blown juggernaut.

I agree, but I think Sony will be at least 6 months to 1 year behind Panasonic, mainly because Panasonic already had proven 4/3 sensor / lens technology and the AVCHD encoding engine from the HMC-150, so leveraging these in to a mid priced prosumer video camera was a great move by them.

Sony is terrified of harming their prosumer camera lines, which is why none of their consumer video cameras have something as simple as a 24P mode. ( Canon and Panasonic consumer cams have had 24P for a few years now )

I feel that Sony will sit on their hands, much like Canon prosumer video did for the past couple of years, because they are not willing to take this risk.

The NEX-VG10 is a "dead-duck" as far as market share goes. It's too expensive and awkward for consumers, with virtually no prosumer features for the professionals. ( I was surprised at how bad the moire is with this camera, and I don't understand why Sony didn't fix this )

The problem with "servo-driven models" will be the cost of the lenses. I expect a servo-driven prosumer lens that covers the 4/3 format to cost upwards of $3,000+ ( maybe upwards of $5,000+ ), which might be too expensive for this new large-sensor prosumer market.

Being able to buy a fast and sharp Panasonic 20mm f1.7 prime for under $400 is what I think the AF100 market is going to be about. I expect to see a lot of new fast primes in the 4/3 market in 2011-12, with pricing in the $500 - $2,000 range.

I hope this holds true, as it will be interesting to see RED finally have some competition in their price range.

I agree, but so far Sony has done little to clear up this misconception. When Panasonic announced the AF-100 the day before NAB opened, it really seemed like just Sony threw together a large-sensor "affordable" mock-up to show that they were still in the game. The timing and the lack of details from Sony seemed very odd at the time.

...Which might be justifiable, as this is the first prosumer video camera to deliver a DSLR video image without all the DSLR problems at a $5K price tag, and that is a big deal to many shooters.

The AF-100 won't replace ENG cameras for ENG style work ( I'm keeping my HMC-150 ), but I definitely plan on buying one for my corporate and indy film-making work. ( I'm not an early adopter, so I'm going to wait until May before I take the plunge. I want to be certain all of the bugs have been shaken out. )

Hmmm. I think Sony has equally proven comparable technology in their consumer still cameras, and surely AVC-HD has been one of the most criticised elements of the AF101 design? Many people have said why couldn't they have AVC-Intra 100 or XDCAM 422 50Mbs?

If Sony do bring a similar product to market, I hope it will have at least 35Mbs XDCAM as the codec (ideally 50Mbs) - not AVC-HD.

Andrew Stone November 3rd, 2010 07:23 PM

Guy,

I fully back what you are saying about the AF100. In your position the AF100 makes complete sense for all the obvious reasons, not the least of which is the matching or close to matching colour space you will have between cameras since you already own a Panasonic cam.

My hunch is the "35mm" camera will be around 15 grand US, street price that is, and maybe lower particularly if they leave it as an XDCAM EX camera. They might opt to sell "the brick" without a sizable viewfinder below 10 grand, who knows. The competition right now is fierce with not only in units to be sold but also mindshare. Panasonic has such a compelling product that people could jump ship. Everything will depend, in my view, on how well Sony handles this in the next few months. Their first window to navigate is the next 4 to 6 weeks by stemming some of the tide shift that is going on with the AF100 and the second window will be post Christmas CES and then lead up to NAB.

If Sony doesn't pull themselves out of their corporate shell and engage in the guerilla style internet marketing that Panasonic has done they are in big trouble.

As a +20 year veteran in the advertising world, I am very impressed with Panasonic's prowess in generating user enthusiasm over this new product. Jan Crittenden is to be commended. Who BTW has been nothing but gracious in a competitive manner towards Sony. I have not seen one cheap shot come from Panasonic's bow towards Sony and I have been watching this unfold very carefully.

Like I said in a previous post, I hope Sony is taking copious notes on this as they are being seriously schooled on this right now.

The one thing I disagree with is the "throwing together" of the 35mm "behind the glass" camera for NAB. I would have thought that earlier and did in fact but it was explained to me the process that the big video camera manufacturers go through in making a camera and that camera, according to this process was at the mockup stage that Sony or Panasonic for that matter would have about 6 to 8 months before the production version of the camera is finalized. It is commnplace to have prototypes like this with port holes covered up with tape and so on.

If Sony is true on their word that this camera will be released in EARLY 2011 then we should seen a near finished prototype at this late November press meeting that has been rumoured about recently.

Many people have seen lots of bad AVCHD and assume that all implementations of AVCHD are the same, which is completely false. This is why I alway ask if people have worked with native AVCHD files shot with the Panasonic HMC-150, which from my experience is probably the best example of good AVCHD encoding.

...And Panasonic ( or at least their reps ) have explained why:

AVC-Intra 100 : Too expensive for the $5K price point, but you can use the Panasonic AG-HPG20 ( or another high bit-rate recorder ) to record AVC-Intra 100 from the 4:2:2 uncompressed HD-SDI output. I expect to see some enterprising company create a "bolt-on" high bit-rate recorder for the AF-100. ( the side handle comes off leaving 3 mounting bolts, so why not add a bolt-on recorder )

If you've checked Barry Green's comparison between 21 Mbit Panasonic AVCHD and 35-Mbit Sony XDCAM-EX, you can see that AVCHD holds up better than XDCAM-EX, even when XDCAM-EX has a big bandwidth advantage :

XDCAM-EX vs. AVCCAM

Crews.tv posted a great article comparing video shot with the AF-100 preproduction camera that was simutaneously recorded as both AVCHD 24 Mbit and AVC-Intra 100 Mbit, and even posted full resolution uncompressed screen grabs to illustrate that visually AVCHD 24 Mbit comes very close to looking like AVC-Intra 100 Mbit. ( the Crews.Tv guys claimed that nobody could pick out which was which when looking at the footage at their editing station )

Comparing the uncompressed images, you can see for yourself how good the AVCHD CODEC is for low-motion video. I expect to see a much bigger difference once high-motion images are introduced, but for regular video work AVCHD is great.

Crews.Tv Comparison of AVCHD and AVC-Intra

The Panasonic implementation of the AVCHD CODEC is one reason why I think the AF-100 camera is going to surprise many people once they get to see native footage shot with the camera. ( it won't be crappy consumer AVCHD any more )

This would be a very big problem for RED unless they are prepared to be price competitive with Sony.

Sony ( and Canon ) is such a conservative company, I have big doubts that the upper management is ready to adapt to a new internet savvy marketing model.

Jan believes in her own product, and has never slagged any competitor. She almost seems to epitomize the "slow and steady wins the race" no matter what form of craziness is running loose on the web.

It just seemed like such an odd coincidence that this vague Sony camera prototype just happened to show up mid way through NAB. If this was not the case, then I would have expected Sony to clearly explain what they plan on doing with this camera, the way Panasonic did at NAB. It always seemed like the Sony reps were making it up as they went along, with no clear idea of what this new camera was supposed to be or what market they were targeting with it. Just the fact that the price is still so vague today, seems very bizarre to me.

Sony should clear up the rumors and plainly state what this camera will do, who this camera is for, and what it will cost. This is the same type of baloney that Canon dishes out, that does nothing to build confidence or hype in their new product. ( they should take a page from Panasonic and make their stand )

Andrew Stone November 3rd, 2010 08:49 PM

Agree with everything Guy including the clumsiness of Sony's press conference at NAB on this upcoming camera.

Imagine being in a tightly controlled Corporate environment where you can be fired on a moment's notice for not being "on message" and Sony execs find out at NAB that they are being trounced by their primary competitor at the most prestigious tradeshow of it's kind in the World. They have to do something but their corporate culture and fear of getting off message is preventing them from coming out swinging. I think that is close to what happened.

This time the landscape is different. It isn't a matter of incrementally raising the bar and making sure they don't cannibalize their higher end stuff. Things have got so mixed up with their paradigm of incrementally releasing new features with the way Panasonic has delivered so many goods on this new camera.

What hasn't really settled in here or with the general Sony camera user is that the version of the AVC codec and bitrate that Panasonic is using yields as good and in some instances a better result that XDCAM even with heavy movement in the image. It's all in the I,B and P frame cadence, as you know, but knowledge of this isn't widespread yet. Yet. BTW I am a Sony user.

I generally like Sony products and admire what Sony created with both the PD-150 and EX-1 cameras when they were first introduced. ( both are fantastic cameras for the respective times )

...What got me to switch over to Panasonic was the DVX-100, which while limited by the DV25 format, still produced such beautiful color when properly tweaked. The documentary "Iraq in Fragments" winning "Best Cinematography" at Sundance 2006 is a testament to the DVX-100 camera and the color it records.

Upgrading to the HMC-150 and working with the AVCHD files it creates, made me realize that AVCHD is a damn good CODEC when properly implemented, but few people have seen this type of high quality AVCHD footage, so this CODEC gets slagged all the time.

Yes, my experiences are with HMC151 files, and I was somewhat disappointed with the results, at least in 1080 mode. It seems quite good for motion - but gives noticeable static artifacting around sharp edges, at least on a full 1080 plasma. The artifact patterning seems to twinkle at the GOP rate (about twice per second) which makes it pretty clear that it is a codec issue. Maybe it's less obvious on a camera that's not quite as noisy as the HMC151?

I remain unconvinced by the explanation. Canon have put a fully approved broadacast codec into their far cheaper XF100, and still using cheap memory - why can't Panasonic do it? AVC-Intra 100 may have too high a bit rate for SDHC - but be fine for SDXC. An AVC-Intra coder chip shouldn't cost any more than AVC-HD, so the only penalty should be the enforced use of SDXC.

If you've checked Barry Green's comparison between 21 Mbit Panasonic AVCHD and 35-Mbit Sony XDCAM-EX, you can see that AVCHD holds up better than XDCAM-EX, even when XDCAM-EX has a big bandwidth advantage :
IIRC, Barrys results were comparing motion handling, which is only one aspect of the "goodness" of a codec. I don't believe he ever compared them with areas of high levels of static detail. Based on what I've seen with HMC151 files, I suspect that would have lead to different conclusions about that aspect.

Crews.tv posted a great article comparing video shot with the AF-100 preproduction camera that was simutaneously recorded as both AVCHD 24 Mbit and AVC-Intra 100 Mbit, and even posted full resolution uncompressed screen grabs to illustrate that visually AVCHD 24 Mbit comes very close to looking like AVC-Intra 100 Mbit. ( the Crews.Tv guys claimed that nobody could pick out which was which when looking at the footage at their editing station )

Comparing the uncompressed images, ............
There is a huge problem with that article, which I've already commented on in the thread about it. Namely that you are not comparing the AVC-HD footage with uncompressed - you're comparing it with AVC-Intra 100. As said before: "Both AVC-Intra and AVC-HD are (unsurprisingly!) based on AVC - and it is highly likely that for STILL images they will therefore each take a similar approach to how they compress. In other words, slight differences between them only tell you how they differ - not how good OVERALL either of them is.The difference map approach is far more revealing when the tested codec is being compared directly with uncompressed.

I could just be dreaming up a non-issue here but feel it's worth discussing... it seems an odd decision for Sony to have designed a body with a native PL-mount (as seems to be suggested on the CVP product page).

(IIRC) PL has a flange distance of 52mm while Nikon and Canon have 46.5mm and 44mm respectively. This means all those stills lenses will be forced to function like macros and all lens distance markings will be thrown way-off, not forgetting the inability to focus at infinity! Don't know about the rest of you but I'm in no position to even consider replacing my crate-load of Nikons with PL equivalents!

I really hope the native mount turns out to be something much shorter (maybe like the EX3 at around 28.9mm, or even E-mount at 18mm) so that there is far more choice for lens(+adapter) options - seems a no-brainer to me, just hope Sony engineers have thought the same way. Alternatively, perhaps Sony has another model in their pocket that will sit somewhere between this and the VG10. Hmmm... so many questions!

Sony need to clarify these basic details soon, or at least make some sort of pre-announcement ahead of the late-November press event. The internet rumor-mill left un-checked can quickly damage perceptions if there is too much fog hanging around new products. Sony should recognize that there is a big difference between "creating a buzz" to feed the followers and "creating a fuzz" that feeds the doubters. I'd say that we're still very firmly in the "fuzz" phase!

I've not experienced the artifacting that you are describing. Some people are disappointed by the resolving power of the HMC-150 imagers which are not full 1080P, but rather something closer to 720P. ( Barry Green posted about this, if I remember correctly it's something like 1440 x 810 pixels ) I knew that it wasn't a full-raster camera when I bought it, so this did not bother me.

The Canon camera you are referring to is NOT a large sensor camera, and it is NOT a camera with an interchangeable lens mount, thus you are comparing apples and oranges. Completely different cameras.

Currently there is no other prosumer large sensor video camera, and I expect the AF-100 will keep this market to itself for the next 6-12 months.

If you had actually taken the time to properly read Barry's article you would realize that Barry stated that the AVCHD and XDCAM-EX CODECs performed the same for low-motion subjects, but that the AVCHD CODEC was a "significantly superior" when the more difficult high motion subjects were filmed. Here's a quote from the article:

"So -- conclusions? Easy -- AVCCAM's 21mbps PH mode is a clearly superior codec over XDCAM EX. No question, no argument, no doubt. While XDCAM kept up with AVCCAM in almost all the testing, it took nearly 70% more space to do it. And then there were the codec-stress times when AVCCAM was just significantly superior. Any way you slice it, the recorded image of the AVCCAM was as good or better"

This issue is not about how good the CODEC is compared to uncompressed raw footage, the issue is about Panasonic's choice of using the AVCHD CODEC when some people think that other CODECs might have been a better choice. Which is why I posted the link to Barry Green's article that demonstrated that the Panasonic 21 Mb implementation of the AVCHD CODEC is "significantly superior" to Sony's 35 Mb XDCAM EX CODEC. Lots of people like the Sony XDCAM EX CODEC, so they should love an even better quality Panasonic AVCHD CODEC.

I would be curious to see a direct comparison between the Canon 50 Mbit 4:2:2 CODEC and the Panasonic AVCHD CODEC, as I have a feeling that the AVCHD wouldn't be that bad. ( 4:2:2 color space will always beat out 4:2:0, but the actual image might be comparable )

The theory is well defined on this, and mathematically very similar to Bayer theory. Pixel shift will give a luminance resolution improvement of up to 1.5X on the native sensor OVERALL. When H&V pixel shift are used together (as in the 150) that means you get a factor of sq rt 1.5 overall - about 1.2x on each axis. So expect 1.2x(960x540), or about 1150x650.

This matches well with what is observed in practice - no observable resolution change when switching between 720 and 1080 recording modes.

1440x810 is what can be expected from a 1 megapixel sensor in the arrangement used in cameras like the Z7, the layout arranged to equalise res in H and V axes.

No - the Canon is not a large sensor camera, and I never said it was. I only said that Canon have proved that it is possible to get a fully broadcast approved codec into a camera at a pretty cheap price. No mention of sensor. Putting the same or comparable codec into the AF101 in lieu of AVC-HD shouldn't add much to the price in technical terms. Marketing's a different matter.

I suspect the confusion becomes because to Panasonic "fully broadcast approved" now means AVC-Intra 100, and at the time the camera was under development that meant P2 to handle the data rate. Nowadays, SDXC can handle 100Mbs comfortably.

The only other thing I'll say on codecs is that the EBU did highly extensive testing on acquisition codecs not long ago at a very scientific level. They gave XDCAM 422 50Mbs and AVC-Intra 100 full approval. Those two codecs are fully approved - AVC-HD isn't.

Well, except for the Sony NEX VG-10 that is. It is not nearly as professional as the AF 100 is cracked
out to be, but I WOULD call it a 'prosumer large sensor video camera' but that's just my opinion.

And as far as opinions go, I have yet to see the CAMERA that shoots AVCCAM that looks nearly
as good as the video from the EX-1 or 3. Again, just my opinion, and also, it MUST be noted, that
this is probably because of the CAMERAS that shoot in the AVCCAM's format and NOT the codec
itself. My suspicion is, that the EX cameras produce such nice images because of the larger chips
and their non pixel shifting nature, as well as the very nice lens on those cameras. I would guess,
that a camera that did the same and shot into AVCCAM would also look very good......and I
expect the AF-100 to produce imagery on par with the EX series of cameras with the added benefit
of shallow depth of field. However, I have decided to wait for real world footage, as I don't like being
one of the pioneers on the 'bleeding edge'.

Paulo Teixeira November 4th, 2010 07:20 PM

The HMC150 is really not the best example to determine the codec quality. In good lighting, the HMC40 is much more detailed.

I was very keen when I first heard about the NEX VG-10, but then I was expecting it to have the same features as the top of the line Canon or Panasonic consumer cameras. When more details came out, I was disappointed that Sony was still building crippled high-end consumer cams. I honestly don't see a market for this camera as I think it's too awkward for amateurs to shoot with, and it lacks most of the features that prosumer shooters want.

I agree completely. It has nothing to do with the AVCHD CODEC and everything to do the rest of the camera. I think the AF-100 is going to be the first AVCCAM camera from Panasonic that will seriously challenge the Sony EX-1 / 3 cameras for non-ENG work. ( the same goes for Canon's new XF 3xx line )

I expect the AF-100 to be a big seller once it's in the stores. I think it will sell so well that Sony and Canon will be forced to release their own equivalent cameras in order to stay competitive, and the prosumer market will be permanently changed for the better.

...We are talking encoding quality, not how detailed the image is. Yes the HMC-40 has full raster 1/4 inch chips and shoots more detailed images in good light than the HMC-150 does.

Yeah, I agree, that's why I was calling the NEG VG-10 a 'prosumer' as opposed to professional
camera. However, maybe it's just a consumer camera.....I haven't done anything more
than look at some of the video it produces, haven't had my hands on one at all.

As for the AF-100, I sincerely HOPE it is a HUGE seller and forces Sony and Canon to release
something similar and the ensuing competition keeps them all producing better and better cameras.
That way, when I DO decide to buy one of them, probably next year sometime, I will get the
most for my money!

I still say using the HMC40 as an example is better than using the HMC150 as an example. The chips matches the EX1r more so than the HMC150 (It's mostly a size difference) and because of that, a codec test would be more accurate.

I was basically agreeing with some that the codec alone doesn't determine quality but at the same time, I was also saying that an HMC40 is better to go against the EX1 than an HMC150.

Well the press announcement date for the 35mm sensored Sony camera has been announced by a reputable film magazine. The date is Wednesday, November 17th. Less than 2 weeks away.

Sony 35mm Mystery Camera Film and Digital Times: Blog

What else is under that shroud?

Erik Phairas November 6th, 2010 03:20 PM

Just enough resolution to be true 1920x1080p and APS-C sized sensor please.

Dylan Couper November 7th, 2010 08:54 AM

Eww... APS-C?

That's like asking for a 1970 Barracuda with a V-6.

(I kid... flame suit on and running.... ;)
