Thanks for the feedback Mark!
The image quality isn't the factor that will make choose the A7s. I think the GH4 has quite a lot of advantages in comparison to the A7s and that slight edge the A7s has in terms of dynamic range and overall image quality isn't what's bothering me. It all comes down to lowlight. The GH4 is the most complete camera EXCEPT for lowlight and that really sucks, as the workarounds available aren't good enough.
I don't see the C100 as a valid option at the moment, I would much rather go with an FS700, but even that doesn't seem valid at this time. Thanks for the tip nontheless!
Thanks for the feedback Clark!
Do you happen to have any footage online?
Thanks for your answer Zetty!
Do you happen to have any footage of both cameras online?
Almost everything's pointing me to the GH4 but once I had the opportunity to shoot with it last week and shot at 800 ISO, it was a serious disappointment. I'll have the same problem with the Canon lenses, as I'm planning on buying the MB Speedbooster and using my Canon lenses on the GH4.
True. I was able to use the GH4 for the past week and am quite surprised with the results.
I did a short video in order to test the 1080P - 96fps. I'll leave you the link: https://vimeo.com/139667650.
I'm currently doing some 4K downsampling tests, will post as soon as I finish :).
Thanks for your answer Dave!
The problem for me with the FS700 is that I don't see it as a good investment. It might have some edge towards the A7s II in terms of overall image quality but apart from that it's just an older, heavier and external recorder dependent camera.
Thanks a lot for your answer Dean!
I will probably wait for next month in order to check some reviews. If Sony managed to solve overheating and rolling shutter issues I guess I'm going with the A7s II, even though I find the price difference to be quite upseting.
