it really depends what features you need, the fs5 does 240fps and bursts, fs7 does 180fps contionous. The fs5 has an internal variable nd, the fs7 has 4k 60fps.
I would be so awesome if knefinity did something like the bmpcc, like a small compact camera sized camera with a built in screen and the kineraw colour and codec.
would not recommend at all for vlogging, i have a a7 and the video auto focus is terrible, the screen cant go selfie mode and if you are in the wifi mirror mode to your smartphone you can only take pictures. No video.
Does anyone here know of a lens hat costs around 200, wider than 24 and has really good flare control? Vintage or used modern, doesn't matter. Speed don't matter either
