Panasonic DMC-GH1 brief hands-on: Digital Photography Review

Harrison Murchison March 3rd, 2009 01:46 PM

Provided the price isn't ridiculous this is my next camera.

Bert Reimer March 3rd, 2009 03:07 PM

24p to 60i
 
"*Full-HD (1920 × 1080) movies are output by the image sensor at 24p (NTSC)/25p (PAL), and recorded at 60i (NTSC)/50i (PAL). HD (1280 × 720) movies are output and recorded by the image sensor at 60p (NTSC)/50p (PAL)."(from press release)
Sorry for the newbie question, but what exactly does this mean in terms of editing?

Joey Atilano March 3rd, 2009 03:15 PM

I might be wrong but it sounds like you will have to do the lame pulldown conversion to get 24P.

Does this mean it has the same sensor overheating issue as the d90 and 5d ?

Ed David March 3rd, 2009 08:14 PM

It still looks like it will be the DSLR to beat. AVCHD is a great recording format!

Ian G. Thompson March 3rd, 2009 09:07 PM

It is the DSLR to beat. Even though it has pulldown with the 24p the videos look nice (from what I've seen so far). 17Mbps AVCHD. The 60p is real 60p. The sensor is a little bigger than the D90. You have manual control of the shutter and aperture. I like this cam.

Hands-on with the Lumix HD-enabled DMC-GH1 (Four Thirds User)
“Internally, the GH1 differs from the G1 in having an improved LiveMOS Four Thirds sensor. Panasonic has improved low light sensitivity to improve high ISO performance. Heat management of the sensor has been modified to enable continuous shooting, without interruption, for as long as the user needs.”

The 5D MkII is still king - but at a price. The FF35 sensor and 42mbps MPEG-4 codec are sweet. Hopefully, they will give us manual control (you can work around it), and 24/25p.

BTW, the D90 has a slightly larger sensor than the GH1. APS-C sensors are about 2/3rds that of a FF35 sensor. Micro 4/3rds is half the size of FF35.

Heath McKnight March 4th, 2009 12:38 PM

I believe Panasonic is the only one releasing new DSLRs (and Olympus, I think) at PMA 2009. Nikon only intro'd a lens, same with Canon. I heard Sony wasn't as focused on their DSLRs.

One key thing I have been thinking about though is how much I rely on flip LCDs. This panasonic has it, while the 5D and D90 do not. I'm still waiting for this game to play out. Between Red, Canon, and now Panasonic, this year is bleeding edge for purchasing. I've been preferring to rent. Now let's see some raw footage from the DMC-GH1! :)

Heath McKnight March 4th, 2009 12:59 PM

Shooting video on a DSLR seems like shooting stills on a pro video camera--adequate, but not ideal. I guess RED aims to solve that with their new systems.

heath

Jose A. Garcia March 4th, 2009 04:47 PM

Is it confirmed to shoot 1080p using the full sensor? If so, does it use the same row skipping technique used in the 5D?

Jose A. Garcia March 4th, 2009 04:55 PM

Does anyone know its price?

John Vincent March 4th, 2009 06:26 PM

What sort of shutter? Rolling or "normal?"

Def interesting... perhaps this will force Canon's hand a bit.

john

Jose A. Garcia March 4th, 2009 07:08 PM

For me the most important point is FullHD 24fps and shallow DOF. I've seen DOF tests from 1" sensors and they were more than ok to me. This sensor is even larger so if you put together everything:

- Sensor size a little smaller than a s35mm negative.
- FullHD recording.
- 24P.
- Full manual controls.

You have the closest to a really low cost digital cinema camera so far. That is hoping it's price is somewhere between a Nikon D90 and a Canon 5DMKII or (we can dream) even less.

Of course we'll have to see the rolling shutter in motion, it'll probably use the row skipping thing, so we can expect some artifacts and aliased borders and we still don't know if the compression will be too noticeable.

But this is looking really good...

Heath McKnight March 4th, 2009 08:11 PM

Weren't there a lot of problems with the video from these cameras when you started panning? I thought Jannard from RED posted video from one that wobbled.

Here’s are a couple of videos of it:
YouTube - PMA 2009: Panasonic Lumix GH1
YouTube - PMA: Hands-on with the Panasonic Lumix GH1

Robert Rogoz March 4th, 2009 11:15 PM

Here is a couple of things to consider. The lens looks to be dark- F4-5.6. There is a wide (14-28mm), but also quite dark. So I don't know about the sharpness of the picture over all. Most of good lenses would have 2.8 or 1.8 aperture, 4 or 5.6 are just amateur grade only.
BTW- what would be an image difference between motion jpeg and AVCHD? Particularly with moving objects or panning?

Paulo Teixeira March 4th, 2009 11:38 PM

Theirs also going to be a 20mm lens that’s either f1.7 or f1.4. The only problem is that it may get released around 3 months after the GH1, but then again, you can get yourself a few adapters if you want fast lenses right away.

AVCHD is significantly better than M-JPEG at the same bit rates. It just takes a bit more horsepower to edit it.

Robert Rogoz March 5th, 2009 12:10 AM

Let's say I have a nice set of Nikon lenses- what adapter would I have to use?

There may not be one yet, although if there isn't it probably won't take long. I believe there is a significant magnification factor when using full frame lenses. Anyone know offhand what it is? 2x?

Yes. Exactly 2x.

There's an advantage to using a less than FF35 sensor. You can crank your FF35 lenses open all the way, and not suffer any light falloff or softness in the corners, because they get cropped.

If I were to get the GH1, I'd probably get all 35mm glass, plus one MFT 12mm prime to cover the wide end of things.

John Wyatt March 5th, 2009 04:50 AM

I'm also interested in the downscale method/quality. The integrated nature of the live view from these EVF cameras may provide a better basis for the video, compared to how live view is implemented in traditional DSLRs. Look forward to finding out what's what with this camera and the Samsung NX series later this year. Oh, that camera doesn't have an articulated LCD -- damn, there's always something...

Jose A. Garcia March 5th, 2009 04:55 AM

It seems like a huge step has been taken. The guy was quickly moving the camera while shooting and I couldn't really see any rolling shutter artifacts. At least as noticeable as in a Canon 5D or a Nikon D90.

Of course the camera used to record the clip was a bit far from the Lumix lcd and he was probably using the 720p60 mode so we'll have to wait and watch an actual video recorded at 1080p24.

Just a question. If you use EOS EF-S or Nikon DX lenses you'd get a smaller magnification factor wouldn't you?

Heath McKnight March 5th, 2009 08:07 AM

This is one of the 4/3 cameras, so I don't know if Nikon or Canon lenses (etc.) would work...

No, it would be the same 2x, but it would be an advantage in that they are generally wider for your dollar to help balance out the price/range.

Kurth Bousman March 5th, 2009 12:03 PM

Don't think of the 35mm equivalent focal length . For example the canon kit lens is 18-55mm. So in m4/3 terms, the 35mm equivalent would be 36-110 . Yet I haven't seen any ef-s adapters for m4/3 . There are FD adapters however . Please correct me if I'm wrong. Start looking at the forums for more sources , but here's one for adapters

japan exposures | films and more (formerly Megaperls Japan Webshop)

they also sell a Leica M /m4/3 which , I believe allows you to use the Voigtlander lenses , which are excellent for their price .

Ian G. Thompson March 5th, 2009 03:05 PM

More lens adapters from Here.

Robert Rogoz March 5th, 2009 04:39 PM

Looks like a dud for my needs, as it would not allow for a pro- quality stills. Maybe in the future they will figure it out, but the lens thing kills it right in the starting block.

Paulo Teixeira March 5th, 2009 04:56 PM

A similar package with the Nikon D90 costs a little bit more than the $1,500 MSRP estimate and we all know that street prices are usually less although it wasn’t the case with the G1 but it still eventually went down by a lot after a couple of months.
Nikon | D90 SLR Digital Camera Kit with 18-200mm VR II Lens
The Nikon lens is lightly faster but it doesn’t have all the features of the lens that’s coming with the GH1. You could still wait for the f1.4/f1.7 lens or get an adapter like I mentioned earlier.
Never mind the fact the older G1 is already similar in quality in broad daylight and for all we know, the GH1 may be similar to the Nikon D90 in low light situations since the Live MOS is newer. Never mind the fact that the video modes of the GH1 should be significantly better.

Frank Vrionis March 5th, 2009 05:44 PM

...also, 'full' progressive 50/60 (what i have been waiting for)

Kurth Bousman March 5th, 2009 07:16 PM

Robert - what are "pro quality stills " ? That's changing every year. I'd wait until still samples are posted in a number of sites before I make that conclusion , unless it's based on build quality . I think, maybe Panasonic has made the camera to beat for anyone remotely interested in stills and motion , but we gotta see the images and video to make a call .

The VR lens is quite crap compared to high end lenses- you'll see it any time you blow up a pic for print. Most of the wide range zoom lenses are. If you look at the bag of any pro-photographer they mostly have something like 24mm, 28-70, 70-200, 50mm and maybe a fish eye. All of them are F2.8 or F1.8. Anyway- what cameras and lenses will give you pro- quality- just check here:Getty Images - Unsupported browser detected.
Most of the houses will have a list of camera bodies and lenses accepted. D90 is not on the lists and you'd have a really hard time selling images from D90. Even with decent lenses I would never offer to shoot a paid gig (like a wedding) with anything below D200.

Pro quality still is whatever houses like Getty Images or clients like Patagonia will buy. Even D90 is not on the list. Also a lens with F4.0 will never produce a decent picture you can make a larger print from. IMO this is more like a toy, most definitely it is not e serious still camera.

Kurth Bousman March 5th, 2009 09:23 PM

....no but 30d and 40d and d300 are all on the list , all 12mps or less (the 30d is only 8mps), and I have no idea why you think you can't print large from F4.0 lenses . That's got nothing to do with it. If you want to be sharper you're going to be shooting with a smaller f-stop anyway . The F4.0 lens limitation affects the lowlight video performance a lot more , or maybe the brokeh qualities for portraits in stills . Use a longer lens .

Paulo Teixeira March 5th, 2009 09:25 PM

Robert Rogoz,

My post wasn’t completely directed at you although the part about using adapters was. Besides, I mentioned the Nikon D90 as an example to prove that the GH1 isn’t that much when you compare it to similar offerings.


Would this lens be considered a toy?

Kurth Bousman March 5th, 2009 09:45 PM

Robert - it's widely known the d90 has the same image engine as the d300 - getty just can't keep up with all of the new cameras - the d90 will produce identical files as the d300 - only in the exif data could you tell the difference - getty will be basing more on content than what new dslr is used - we have now reached the practical plateau for still images - Olympus is even announcing this very point today

Kurth- Getty and other houses will not accept anything below D200. So D40, 60 and 70 are out. D2X, D2xs are on the list, so is D200, D300, D700 and D3.
