LUMIX GH5 *Successful* Autofocus Tests!
Photo Moment - April 06, 2017
OK folks, you've seen all the FAILED GH5 autofocus tests… now watch the video where I took the time to make it work.
**READ THE PINNED COMMENT BELOW**
Hey everyone… this video was recorded externally to the Ninja specifically so you could see the the on screen display, face tracking, etc. I wasn't aware that the autofocus performance changed when recording vs not. I haven't watched all of Max's videos so if he's said that, great, but I didn't know. This wasn't recorded this way to “deceive”, so to any of you saying that, you're wrong (and if you don't believe me, a) I don't care, and b) I don't care). I am completely honest that I am sponsored by Panasonic so YES I am biased. But I'm not setting out to deceive you, so wipe that idea right out of your head. I will do some more tests recording internally, starting with the settings I ended up with here, and tweaking (if necessary) from that. However I'm probably not going do to anymore tests following this format… it's boring and unrealistic. I will go out and shoot some real content and check AF as I go, and tweak as necessary. No one shoots real world footage like the tests you are seeing. So I'll start shooting real content. Stay tuned for more tests, and again I reiterate… relax, people. It's a camera. Not a religion. Quit watching reviews and go out and shoot. (update) Oh and by the way, shooting to an external recorder is far from invalid. It's a totally legitimate way to shoot and how many, many people do. So from that regard, this is a totally legit test, too.
Auto focus problems will always be fixed as its mostly user errors. With lighting subjects correctly the camera will know that is your main focus point and lock on, Same with Sony same with Canon. Learn the camera or move to a system you find easier to learn simple stuff.
Would it be possible to turn on CC in previous videos?
(Also... Dont forget... Most interested in 60p internal with 24p external, not 60 30.)
4k 60p internal
24p external
10bit
highest Mbs available.
V-log with any LUT applied you desire.
Really just want to see if we can get those two frame rates captured it'll be a big deal for us.
I'm curious if battery wears down slower if you're running a Vlog file and also applying an LUT. Don't really need to know ... But if you're looking to do a test that probably no one else will. That might be a good one.
For us, we are shooting on a Ronin M. So IF you have one round or access to one... It would be great to see if any of your focusing settings of choice, allow for a moving subject and camera to keep up.
And I'd go further to say. At a narrower than human eye field of view... So something like 35-40mm on that new Lecia glass. Because wide open, more things would be in focus at the same f-stop. And that's too easy. It also is too typical a Gimbal like shot, something we don't want any part of (looking or feeling typical.)
Moving subject should be moving moderately... Say.. Dancing in place, not running or skateboarding around. But just rockin out to some tunes... And the camera. Moving in and out and around.
THOSE are the conditions under wich we will be using these little beasts.
I'm not sure what I'm going to do with the 3 cameras we will be using that won't be on Ronins, but will be mounted on sticks and will be used to roll for over an hour. I fear with the 400mb update, we won't be able to run off of one battery. Test showed up to 2 hrs in 4k on one battery, but I'm not sure if that will be even remotely close recording 400mb a sec. So I think all three might need grips and maybe just run those with DC power and take their batteries and use them for backups on the 3 cameras in the Ronins. Though probably never will be used as those cameras will only be running for the length of a song. It's a one take ordeal. Talk about nerve wracking! Take a world famous celeb.. And you get one song worth of time. To make SIX images of for all of history... Maybe I'll shoot it on film every once in a while just to really intensify it!
I may just have to personally cook you lunch when you visit the studio once were up n running.
Also, I spoke with The Camera Store again to get a grip on what battery life will be like shooting 4k at 60p(though I think I told them 24p and I'm betting it matters..) Needed to know if I'll be safe to roll for just over an hour. (If so this saves us from having to add battery grips to three camera$) They reported back (again I believe though they were judging based on 24p) that 2 hrs of the recording could be expected per battery.
HOWEVER. What I failed to find out (they were curious too and said they will get back to me.. Haven't heard from them yet though.) is if you are ALSO recording externally while recording internally. If that 2 hrs drops !?
Am I giving you enough ideas for new videos....? =)
The absolute minimum requirement of C-AF in video is to be able to follow a target moving reasonably slowly towards or away from the camera. AFAIK there is no set of parameters that would make the GH5 do this without it also "hunting" at some point, which looks absolutely horrible.
The AF in GH5 is fine for 90% of shooting types. If someone wants the best in continuous AF then they should buy a 5DMKiv for $3500 instead of $2000 GH5.
For me, I plan to identify the best settings for my use cases. Hopefully we can save custom settings so that I can quickly switch between them.
