Lee: “I own the Panasonic 35-100mm lens. A wonderful lens, but several people have been discussing a behavior of the lens OIS – micro jitters when shooting movies hand-held. There are several movies showing the behavior – including one I made showing a comparison of different Panny lenses. I was wondering if you might be able to draw attention to the issue from your contacts at Panasonic?

GV: “Not rumor, rather a tip: Use the rubber eyecup from the Zacuto Z-Finder as an impromptu eyecup for the GH4. The inside diameter of the Zacuto eyecup will fit perfectly around the GH4 viewfinder and is flexible enough to stretch around the built-in existing eyecup. The only downside is that the LCD is now blocked from being moved. I got the idea to check my parts bin from (gh4crew.co.uk/?p=406). I took the cup off my Z-Finder and, presto, it worked!!!”
Richard: “People say that Olympus can’t make videocameras. Well they have for years, but they make high speed proffessional video cameras http://www.olympus-ims.com/en/hsv-products/ Btw. they use global electronic shutters“

GH4 is surprisingly clean and if you add a speed booster man get’s very nice results even in low light :).
I think that the GH4 is doing some EXTRA NR as its files look softer than the others at higher ISO, not that it bothers me as I have never shot or taken photos over 3200 ever lol
I think they had a lens out of focus. It simply cannot be that soft even at ISO1600.
they missed focus indeed… shame!
yep, they missed focus. they couldn’t have it look better than their beloved C100
GH4 is softer doe to a poor focus from the user. The files, even at high ISO’s are very detailed and sharp. I have the camera and I can confirm that.
Sorry ENO I was commenting from my experience with my GH4, which on my tests at high ISO were also notably soft. Though as I say for me personally it is of no importance. I am for sure no expert at video and it may just have been user error
I personalty own the Gh4 and I confirm the camera produces an extremely detailed 1080p resolution, even at high ISO. If you compare the files with 5D mark 3, the Canon looks like a 720p camera (and I’m speaking of only full HD, not 4K downsized to full HD).
They shot each camera at 1080p for a level playing field, but it’s good to note that in actual use you’ll have a lot better results shooting a GH4 at 4k and downscaling to 1080p. This is an extra step in your post workflow though, so it’s reasonable for a test like this to ignore that. They also didn’t use the 5D’s ML hack, which would have yielded better results.
Even using downscaled 4k I wouldn’t expect the GH4 to beat a C100 or come close to an A7s in a low light comparison, but if you’re shooting a GH4 keep this method in mind.
Agree, the best way is to shoot 4K with NR turn to -5,then clean in post. I managed to clean ISO 3200 files so well, that they look as good as the minimal ISO and the detail was still there (quite a lot of detail actually). If you downscale the cleaned 4K to full HD it looks better than anything else. Unfortunately ISO 6400 is the limit, but we must be honest, who will use a higher ISO for commercial proposes. + If you add a speed booster, you get an extra stop of light in the equation.
the GH4 looked cleaner than the C100 up to 6400, that surprised me. They should have shot in 4K and down sampled.

@Richard and others: here you can see one of the Olympus high speed cameras doing a great job, to help study the jellyfish species:
