Panasonic LUMIX GH5 for underwater video

[thetrickster 328]

Are you at the show Richard?

 

I'll be there from thursday.

 

I've seen the "universal" Easy Dive housings before on the previous Boot instalments, and they are probably not for me. ;-)

 

I went a couple of years ago, and from Spain, tbh didn't feel worth it. But it might be different now.

 

I'm not keen on their housings either tbh.

5.Will the back button focus work while recording?

The GH4 has this so I assume the GH5 will. The GH4 got it with a firmware upgrade.

I know, I know. Someone posted it here.... I already had upgraded the firmware but I didn't realize of this improvement!!!

Might have my hands on a GH5 (no housing though!) for the weekend. Any tests I should do that haven't been covered by everyone else on YT?

Can we assign one of the Fn buttons to do TRUE one-touch WB ?

 

Got another questions, but forgotten at present - will edit post once I remember.

No dice on the one-touch WB, though that is definitely a great idea. You can assign any of the WB options to one of the Fn buttons, but all that does is provide quick access to that preset/mode.

Would be interesting to see how much better the gh5 is during low light scenes.

Come on guys!!. This Thread is dead and we've had the GH5 already out there for a few months!... Nauticam already released its housing as well as Ikelite did (vacum valve and doesn't look like its classical line of "rubish plastic" housings) ... NOT A WORD HERE??

Ikelite's port chart seems to lack of focus gear in most ports... but is way more cheaper. I wish someone had tried it and could post some coments.

Has someone put the GH5 down there???... noise behavior in deep shots???. MWB in low light conditions. Grading of 422 10bit footage????.

Yes!, I have so many questions!!!... I can only hear my echo here!!!

Planning to make the switch from my AX100. The 10bit color space should really help quite a bit in color correcting UW stuff - I would hope! And if they deliver on their firmware update promise for summer (4k 10bit 60fps), then I don't see anything comparable and reasonably priced/sized coming up on the camcorder front. Been playing around with the GH5 overland for 2 weeks now. Not very intense as I had other things going on but hope to dip more deeply into it the coming days.

 

I'd preferably want to wait for availability of the Aquatica housing to compare this with Nauticam. But if it takes much longer (and gets too close to my next trip-date), I may order the Nauticam housing.

I'm considering taking the big leap of upgrading from my old GH2 to the GH5, but I'm starting to get seriously worried by all the reports out there of the GH5 having autofocus issues. Does anyone have real-world experience of how it handles in this regard underwater?

 

It's all well and good having 4k 50fps, 10-bit 4:2:2, 180 fps (manual focus only?) etc. etc. etc., but if the camera is focused on particles in the water rather than the intended subject, then the shot is screwed anyway!

Autofocus issues other than GH4 already has?

It would be really nice to have a good thought-for-video-shooting autofocus but is not a big deal for me because most of the time I would still use manual focus.

Anyway I believe that the autofocus works fine and really fast... is made for a still camera. To have a usefull autofocus for us I guess it shoud have a different behabior or "mode" when recording video.

Same thing with f steps... no point in changing aperture while recording because it "jumps" roughfully from one one value to another, not like a videocamera does.

GH54 or GH5 are still a photography camera:(

It's probabably not worse than the GH4.

 

However people seems to expect more in 2017 than 2015. Especially since several other hybrid cams have superb autofocus.

Have you seen the reports about the autofocus working considerably better if you use an external recorder?

 

This seems to indicate that the internal processing power is really limiting the performance.

 

Also, everything is much worse in 4K than 1080p. Also the manual acknowledges this fact.

[adamtaylor 27]

For those interested I posted a couple links to footage from my first dive with GH5 under Editing, Post Production etc.

Constructive criticism would be welcome as I am new to Underwater Video

Thx for the replies.

 

@adamtaylor - your video was reassuring! Some of the things I saw on the internet were suggesting that the autofocus was virtually unusable, but your autofocus seemed perfectly normal to me.

 

Cheers,

When you say 'auto focus' do you mean 'continuous auto focus'? The GH5 has no issue at all with auto focus (automatically obtaining focus before the shot/video starts. Continuous auto focus is where there can be some challenges, but with a fisheye I don't see why it would be needed unless you are doing close focus/wide angle video.

[Etc 11]

In my case, when I mention auto focus regarding video shooting I always mean continuous auto focus. In any camcorder is what AF means.

[dreifish 353]

Etc, the continuos autofocus is contrast detect based, so probably no more usable in video on the GH5 than it was on the GH4, or, for that matter, pretty much every other large sensor camera out there other then a few Canon offerings with dual-pixel autofocus. CDAF is always going to hunt a bit when shifting focus, which looks terrible in video. Even the Sony cameras which have PDAF don't really do that great if you leave continuous autofocus on for underwater video -- they'll often shift focus from your main subject to particles or small fish closer to the lens, ruining your shot. So I'm rather distrustful in any sort of continuous autofocus for wide angle underwater video. There's simply to many things that can distract the focus from your main subject and no good way to tell the camera what your main subject is.

 

But honesty, shooting wide lenses and with narrow apertures as is normally the case with wide angle video, you can just pre-focus and lock focus before filming and be ok in the vast majority of cases. Now for macro, I would love to have a good continuous autofocus system since critters are always moving and your depth of field is miniscule. But I don't know of any such systems out there. Perhaps the Canon 70d/80d/7dII/1dxii/5d4 or their cinema-line cameras can pull it off. I've never tried them or seen underwater footage from them shot with continuous autofocus, so I can't really comment.

[Davide DB 413]

When speaking about DSRL, continuous AF is a complete bullshit. It's like unicorns: everybody speak about them but nobody caught them on tape

Maybe Canon latest dual-pixel AF makes miracles but, as dreifish wrote, I've yet to see it working under all condition. Once you have done enough experience with prefocus and lock-AF you can count on it. On the contrary I would never rely of C-AF on a serious shot.

I know that macro is different but current technology on large sensors still doesn't compare to small camcorders AF.

An u/w pro shooter friend of mine switched from GH4 to Canon 1DXii and says he's now able to leave AF on for most stuff.

Sounds nice. Canon seems like the the best option for underwater work, but the 1DXII is ultimately unappealing given the price. Since white balancing seems to work well on the GH5, I feel like autofocus is a small enough thing to sacrifice in return for the $7000 when you add up the body and housing.

 

Maybe Nauticam will come out with a (well-priced) housing for the new Canon C200. That camera seems to tick a lot of boxes for both topside and underwater shooting.

[Etc 11]

I'm not concerned about the AFC. As I said I don't find it necessary in most of my shots (I don't have my macro set up ready thou). But it would be great to color grade a 422 10 bit footage. UW color grading is a very challenging task because some times you have to push the video data to the limits. And I find it impossible to find any UW footage downloadable to mess with. Because still have my doubts with a 150Mps 4K video holding 10 bits at 422... its seems a lot of compressing to me. And the 400Mbs didn't arrive yet as far as I know.

My point is:a worthy 4K 422 10 bit running in my computer without crashing it?... enough to get the GH5 despite other new features

This sunday, my plan is to film some nudibranches with my Gh5. If you want, I can shoot some footage for you in 10bit 422. What kind of shot would you like to have to colorgrade?
