Re: Three new JVC 4K cameras
 

Yes for the sake of accuracy I guess it's best to quote the exact numbers. The Sony 1" has a 13.2 x 8.8mm sensor with a diagonal of 15.9mm and in 16:9 mode has an active are of 14.2 million photosites whereas the JVC HM200 1/2.3 sensor has dimensions of 6.4 x 4.8mm a 16:9 active area of 9.03 million photosites. So yes to be accurate the Sony sensor is 3.78 x the size. Although as you indicate Cliff these facts are but one small part of the sensor performance equation.

Will be very interested to see how these cameras behave in the real world as specifically I really like the concept of the LS300.

Being curious I did a bit of digging on Altasens a while back to find out there background. Quite an interesting back story. Found this.

"Altasens started off in the USA as the Rockwell Scientific Company in 2000. They became well known in the video conferencing imaging industry. It was then majority owned by Olympus via their ITX Corporation back in 2004. Kenwood then bought into JVC in 2008 and then after fifty-eight years of JVC / Panasonic partnership Panasonic sold out of its shareholding in what had become JVC Kenwood. JVC Kenwood then purchased Altasens in 2012 to make sensors after Panasonic's withdrawal in late 2011. This is JVC / Altasens first real venture into 4K imaging. First tests out of Japan say it has some rather some interesting color science."

What interesting color science means will no doubt be widely discussed when these cameras arrive. I just hope they have improved it somewhat over the first 4K demo that Altasens uploaded. Highlight handlng appeared to be an issue in this example:

Re: Three new JVC 4K cameras
 

Authorized JVC Dealer now showing the price at $3995! Looks like it will be ready by NAB 2015.
That's good news!

Re: Three new JVC 4K cameras
 

Not only that, but B&H (they're a sponsor of this site, I'll name them) has the HM200 for $2,695 and the HM170 for $2,295. The HM200 is looking mighty tempting.

Re: Three new JVC 4K cameras
 

There are some real special introductory deals on the LS300.....as soon as I can, I'll post them and trust me, you are going to like it!

Re: Three new JVC 4K cameras
 

Sorry, Jim, I forget you've moved to another company. EVS' prices are the same as B&H. Good deals!

Re: Three new JVC 4K cameras
 

Yes, the selected dealers will have the same locked price...much like Canon has done with the C series...

Re: Three new JVC 4K cameras
 

The LS300 has been getting a lot of attention interest of late, but I am wondering about the GY HM200. B&H indicates that it is due there the beginning of March. I have seen several shots from the camera from Europe but really nothing of substance, and nothing here. Seems like there should be much more chatter and video about the camera considering that early March is like…now. Anyone heard anything or seen any footage?

Re: Three new JVC 4K cameras
 

JVC will have a stand at BVE in London, which starts tomorrow - so I imagine that will generate a bit of interest as those of us who are visiting BVE will get a chance to see it/hands on with the camera and the other new JVC offerings.

Its not on my personal priority list for things to check out (when I visit, probably on Wednesday).... but I am sure those that are interested will report back with their first impressions pretty soon.

Good Review:

News Shooter | Testing out the JVC GY-LS300- A 4K budget Super 35mm camera with a Micro 4/3 Mount

Re: Three new JVC 4K cameras
 

I was at BVE in London yesterday and had a look at the LS300 both on the JVC and CVP stands and picked up a brochure. I found it to be a very clever little camera and was far more taken with it than I expected. Assuming image quality is decent then I can see this LS300 appealing to many. I certainly found it far more interesting than the PXW-X70 (now that we know the details, cost and June 2015 timing of Sony's 4K firmware upgrade option for that little cam). Sure, as in that review Troy posted above, the EVF is poor on the LS300 - but the cam overall has a lot going for it.

One more general comment about BVE/the way the industry seems to be moving...from what I can tell. 4K was EVERYWHERE at BVE. I lost count of how many Sony FS7s I saw on all the various stands or how many times I saw 4K on signage. I'm sure I made a sound decision recently - that every camera I buy from now onwards must have 4K capability (even if it'll be a while before I expect to deliver in 4K to my corporate clients).

Wow, that's a great overview from B&H. Thanks for posting this, Troy!

Re: Three new JVC 4K cameras
 

Great rundown on the three cams. Now, which one is in the budget for me?

Re: Three new JVC 4K cameras
 

Hi,

questions on the JVC GY-HM 170

the 422 is 8 or 10 bit?

can be used in full manual?

which is the general level of jvc camcorder respect to Sony, Canon and Panasonic?

Re: Three new JVC 4K cameras
 

Here is test footage in 24p at 1600 ISO...
https://www.youtube.com/watch?v=z8t6...ature=youtu.be

Re: Three new JVC 4K cameras
 

Check this video starting from 01:10 to see how much noise the camera produces, not sure how much 18db is in gain but 18DB already seems to be very noisy while 24db seems to be unusable, it doesn't look like a good low light performer to me.

Re: Three new JVC 4K cameras
 

Thanks for sharing the footage Jim. Looked great--and then the hand came in. Sorry to see that the camera did not do well in holding the highlights on the hand. I will keep optimistic--I am really pulling for this camera.

Re: Three new JVC 4K cameras
 

I like the footage we shot so far....we put it in tough situations. We'll shoot the rest this weekend with some night and daytime using the standard cinema mode (last week we shot in the cinema subdued mode to try and mimic a log stetting)...

Re: Three new JVC 4K cameras
 

I for one would like to know when the image would be falling apart at higher iso's when I would spend 4K on a large sensor camera. A clean 1600 iso is something I would expect from every camera these days but what's more interesting is how it will handle higher iso's, would you say then that 1600 iso is the highest usable gain?

Re: Three new JVC 4K cameras
 

From what we can tell so far, 1600 is fine, 3200 starts to get some noise going but still very usable, and 6400 is too much...at this time. I'm in constant contact with the head of engineering and they are working on getting better above 1600 and will be adding noise reduction, all through updates that will come very soon. Again, the cameras ship the last week of this month which is a fair amount of time to do some tweaks to the system........

Re: Three new JVC 4K cameras
 

Thx for the info and good to see JVC has interest in improving the performance. It was not my intention to come off as negative but I think that anyone that wants to buy a camera where there is little known about wants to know what's good about it but especially what's not so good about it so they can make a better decision before spending this amount of money. I think it's safe to say that currently those who where expecting canon c100 clean high iso's would be disappointed, not that this is something everyone needs but it's good to know what the limits of a camera are.

Re: Three new JVC 4K cameras
 

wow. the low light with gain puts it into perspective for me. Looks like C100 MK II will be my purchase.

Re: Three new JVC 4K cameras
 

I think you should split this thread three ways, as there is cross talk about two of the three JVC models, some responding to the LS 300 and others to the 200, both being compared to the x70. The 170 seems to have been almost forgotten, and certainly, there are people who are in that market, as well.

Also, for those intrepid camera guys, a four way line comparison between the x70 and the three JVC units, including price.

All of these cameras share 4k or 4k capable cameras, but I wonder how comparable a 1 inch sensor is to a 35 mil sensor.

Also, comparing the LS300 to anything makes almost no sense if we don't understand what lenses are being used with it.

Re: Three new JVC 4K cameras
 

When looking at high ISO performance it doesn't matter which lens or f-stop is used, the noise doesn"t change.

Re: Three new JVC 4K cameras
 

I wouldn't be too quick to judge based on that video which wasn't that great....again, pre-production models. I'd suggest to wait until the units ship.....from what we have shot at 1600 and 3200 ISO, the noise level was less than what this video showed.......

Re: Three new JVC 4K cameras
 

Will you upload the video to Youtube or Vimeo, Jim?

I've found this one today and it shows that the LS300 will do well even at 24dB! Well, at least for my needs...

Re: Three new JVC 4K cameras
 

Cool stuff. Sure does seem like it can swing ISO 1600 a lot better than another example I've seen. 3200 gets a little soft but still not bad. I'd put this ISO performance about on par with the GH4 based on this example.

Re: Three new JVC 4K cameras
 

it looks decent up to 6400, still on my radar, especially for the price.

Re: Three new JVC 4K cameras
 

According to JVC's website, the HM200 has "f5.6 sensitivity". What does that mean, f5.6@2000?

Also, the HM200 lens is listed as f1.2-f3.5. If taken at face, that means that if you zoom in from wide angle, you must add 18db to retain your image brightness. If the lens ramping is similar to the X70 and others, you will have to add that 18db by around 6x into the zoom range.

If it is f5.6@2000, and f3.5 at medium zoom, then this would be the equivalent of an old 1987 Sony BVP5 (first Gen 3CCD camera), with the lens stopped down to f4-f4.5! Not good at all in low light.

JVC, can you confirm those specs for us? Loosing 3 full stops by zooming in is pretty massive.

Re: Three new JVC 4K cameras
 

Jim -- this is good idea from Bill, above. I would be happy to host it right here on DVi.

Re: Three new JVC 4K cameras
 

Bill - same here.
Had it on my list of things to do and still didn't get to watch it. Busy day. So "a second on this" request.

One area I'm interested in is the image stabilization. The JVC web site JVC Pro Product Overview Page didn't mention this but elsewhere I read that there is IS.

"The devil is in the details"

Re: Three new JVC 4K cameras
 

Not the same footage from the EVS presentation but scouting the internets for more footage I found this one. the LS300 is looking mighty good. If this is without cinema subdued I can imagine the image can be far more gradable friendly after a little tweaking.

Re: Three new JVC 4K cameras
 

I have a Canon TV Zoom J6x11 macro lens. Considering my absolute inexperience in lenses, could this lens fit the sensor in this camera, and would this be a C-mount? What will this lens do for me? If it can be made to adapt, what adapter is recommended?

Thanks

Re: Three new JVC 4K cameras
 

I did a little research after getting blank looks from some of you. This lens does not appear to be compatible, and even if it was, the motor will present problems.

Seems like some prime lenses from some of the older cameras could be adapted, though, making the LS300 a more practical solution. What slowed me down on this camera is the cost of a great lens to match it. I am sure the lens included in the deal is o.k., but clearly, as stated by Jim earlier, certain prime lenses will make this camera really shine.

Re: Three new JVC 4K cameras
 

The LS300 is like a sideways DLSR with a handle and camcorder toggle controls. Just wish lenses would meet our wants in these "other" mounts!

At least give us a 16x f1.4 ENG style wide capable power zoom lens and a matching crop setting for it in the LS300.
