Hi, new user here... I've been waiting for about a year now to invest in video-focused gear now since my stuff got stolen in Paris... After being somewhat letdown by the GX8's lack of IBIS while filming (something I would really value for what I have in mind), I think I am ready to go for the A7R II rather than to wait for the A7S II or whatever else might come down the road, especially as I will need some decent gear rather sooner than later Some remaining questions (I know the camera is not out yet, but I figure most of these can be answered already or very soon): 1 - If I get the Speedbooster Ultra for e-mount and mount it on the 7RII, it will allow (or rather force) me to use the S35 4k mode (which I am planning to use anyway) in full coverage? 2 - When speedbooster is coupled with the Rokinon EF Cine primes 24mm and 35mm in S35 4k mode, which equivalent focal length in 35mm "full frame" photo terms would this yield? I can't seem to wrap my head around the math there 3 - I have a bunch of beautiful S16 C primes flying around, and I see there are C to E-mount adapters -- if I shoot S35 4k with these, would I be able to crop out the massive vignette and still arrive at 2K footage with no pixel binning? And would IBIS work? (I assume you can input the focal lengths manually for legacy and adapted lenses) 4 - Any updates on how the A7RII is handling rolling shutter in S35 mode? 5 - I saw some interesting discussions regarding upsampling 4k 8bit footage to 2k 10bit footage for additional latitude in post -- can this be simply achieved by working with the 4k files in the editor and then exporting at 2k 10bit? The posts I saw about this all talked about the GH4 but in principle I assume it should be possible with the A7R II, too? //edit: did some research on this and seems that it's not all as beautiful as it seemed So 4k to 2k for the extra perceived detail and options for post-cropping -- fine! Sorry if some of these questions are a bit newbie-ish, just getting back into the game Thanks mucho in advance!
