Panasonic GH4 - Slow-mo at 96fps and 4K rolling shutter test

[jareckig]

Andrew great test, as always. How video AF works on GH4 with third party lenses? Is it possible to use speedboster and i.e. Sigma 18-35 (nikon mount) with video AF?

What's the quality of GH4 like at 1920x1080 at 50P or 60P? This 96fps doesn't look that great..

 

I would prefer to see controlled experiments showing the differences between 4096x2160 24p, 1920x1080 60p, 96 fps in different lighting conditions. For example direct sunlight with some action in the scene: skateboarding, etc. Maybe some reasonable moving of the camera, as compared to furious waving.. This could show effects of rolling shutter, dynamic range, line skipping..

There is a drop when compared to its own GH4 footage not at 96fps but like many other postings here I would say in comparison to other 1080 cameras it actually looks amazing. Especially the closer shots (dancing into the sun, dog chewing) it's stunning. As for the other request, I suggest watching the video, and check out the recent posts on EOSHD with other tests. Perhaps I will need to wait for you to get the camera to see all the tests that you want to run.

No, it's a passive mount adapter with no electronics. The AF in Nikon lenses is usually optimised for phase detect sensors and the GH4 uses contrast detect so even if it worked through a smart adapter, it probably would be a bit shit :)
