Panasonic GH5 - all is revealed!

I posted it here because I am genuinely curious to see whether someone actually shot an entire short film, documentary,  wedding or music video, or corporate work etc on Auto focus on a camera with dual pixel (canon) or something like an A6300 or even A6500. I think users' exaggerated claims have kind of pushed the facts into the realm of dreams. People say things more for effect than for their actual worth.

I shot the following video with AF only on the A6300 and a came tv single.

I tried out Variable Frame Rate today (VFR). While the feature works fine the codec selection is not so great. At least in 4K, VFR only seems to work when selecting 8 bit 100 Mbps. I am disappointed that it does not work for the 10 bit 150 Mbps codec. I shoot a lot of timelapses in log format (so for GH5 it would be V-Log L) and I would have hoped this camera would let me get rid of my external Atomos recorder. Not so much :(

This to me is a big disappointment. The camera should support 10-bit 422 from 2fps to 30fps. I hope Panasonic can fix this is in a future firmware update. Not being able to under-crank in the GH5's best codec is a let down.

I'm curious how you use your external recorder to do timelapses in log. Do you go to something like 2fps in camera and if so, how does the external recorder handle that? Does it also record in 2fps or does it fill up a 24p container with duplicate frames or something? Very curious about this. Thanks.

I'm not getting the fizz. Normally by now after a camera release I've seen some footage that has. I got the fizz when I first saw some hacked gh2 footage. In fact some of that still does it. Canon raw video. Even the BMPCC, a7s.  I get more fizz from my nikon d5500 vid.   It all seems a bit characterless, a bit sterile maybe (and goddamit Ive seen moire in 4k. Argh!)

This video (due to the short clip lengths and lack of any real focus transition), could have been shot on a manual focus lens with fixed focus  (without transitioning between shots).

Nice edit, btw and nice shots too.

The GH5 seems to have pretty decent AF.  And for something extraordinary, do it yourself via manual focus.

I am looking forward to a lot more video samples from the GH5. I got a chance to play around with it briefly. It has way too many features. And most of them are really stellar.

My man! First video I've seen where somebody has actually adjusted the knee in the Like709 profile. Some people are very excited about this @Fritz Pierre as the colours seem to look very nice.

What can you tell us about the knee adjustments - does it give better dynamic range?

Also, that vid shows the incredible rolling shutter performance @ 180fps. On another camera the blades would be warped.

Thanks, i would love to help you out but this was my first time using it. But it is very gradable, even at 8Bit. If i ever get to shoot something that doesnt move i will try to do a test

Can you get a 1/2 second shutter on your GH5 and capture that on the Atomos in 10-bit timelapse or is the minimum shutter speed with that setup 1/24 of a second?

Just for clarification, the Atomos has features to capture timelapses just fine. I think I can set the shutter speed to whatever I want. That is what I was doing until now with my Sony A6300. I was saying that I wish I could leave the Atomos behind and only use the new GH5. Which I can't unfortunately due to the codec.

I'd like to see less footage of scenery and more of people. So far, the skin tones look a bit red in most of the GH5 footage I've seen (but maybe all Scottish people are super ruddy?). I'd love to see some side-by-side comparisons of the GH5 vs. Blackmagic Ursa Mini, a proper 4K shootout to compare the color science (without any artsy color grades, slow motion, or raw vlog).

My first couple of tests with the GH5 show that Natural is the best picture profile, as it was on the GH3 also. When everything turned down -3 or -4 (contrast / saturation), there isn't much difference with it's close contender Cinelike D. Mind you, Cinelike D is flatter but also some color tonalities are lost. Especially in the greens.

Cinelike D might show a small improvement in DR, but never more than a (0.5) stop. With Filmconvert applied with it's standard curve, the difference in dynamic range is lost and Natural wins with better colors. Some grass for instance has a yellow tinge to it in real life and on Natural, which just becomes a single colored green on Cinelike D.

So for me it will be Natural as the way to go. Like709 has the best colors out of the box, but not the best DR without tweaking every shot which I'm not going to do when shooting weddings. I didn't get the V-LOG update though so I can't comment on that.

Forget about Portrait, Standard, Vivid, etc. I see no reason to shoot in those profiles as they don't offer any more 'natural' color over Natural and no improvement in DR or gradeabillity whatsoever. 

Then the stabilizer. I'm using a Sigma 18-35 with a SpeedBooster XL, so not supported by the camera. I have to manually input the focal length and naturally I can not make us of Dual IS. My findings are that it works fine for handheld shots which are pretty steady or make a small movement or pan. However, I tried to walk with it on and it mostly gave pretty poor results. Similar to warp stabilizer, it was warping all over the place on the side of my screen. Don't expect miracles if you don't have native lenses is my take on it. Oh yea, and it DRAINS your battery. With the GH3 I could go for hours on a single battery. Today I almost went through a full charge in like 90 minutes.

What else? The 4K at 50p is astounding. The image is chrystal clear without being oversharpened. It's not lacking DR unless you start pushing it with very contrasty situations.The VFR is very fun to play with. 120-180 fps is astounding. It's as sharp as a GH3 / GH4 at 1080p, but more prone to moire and aliassing. You have to make sure you have the background (bricks, buildings, trees) out of focus and then you're good to go. Instant production-value.

The camera feels sturdy and professional. The full-sized HDMI is the finishing touch. Recording simultaneously to dual SD cards is a blessing, especially when shooting important events like weddings. No more nervously taking the SD-card out of the camera and put in my computer with shaking hands praying to God that the footage is okay and the card is undamaged. 

Cons I've seen so far:
- Incorrect exposure when having VFR selected in combination with shutter-angle. You aren't shown the correct exposure of the shot until you press the record button. This needs to be adressed. 
- Not as impressed with IBIS as I had hoped for. 
- Battery life decreased. Probably due to Stabilizer and or dual card recording
- Image needs heavy grading to be 'filmic'. But this is the same for all Panasonic camera's and I've learned to deal with it

Great step-up from the GH3 which I've used for 4 years with great pleasure. If the GH5 proves to be as reliable as the GH3, I'm a very happy customer.

Here's the one of the first films I've shot with the GH3. I'm still surprised with what that little camera can do. If you don't have the money, you don't need a GH5 or an upgrade. But if you do, it's great fun and you feel like the future is here.
