Hi Roger,

I was wondering what your thoughts are on using these a7 full frame cameras with Leica M lenses for video work? I know cw started to declick these as cine lenses (M 0.8)

The only thing that worries me is the slight moire that I have seen from the tests that I have done. I am able to lessen the banding effects from the sun by shooting 10-bit external but it still looks like cheap video at the end of the day.

Honestly these lenses on the a7s look like old Panavision primo's, which I am a fan of. 

How do think some ultra primes would look on this full frame sensor in crop mode?

Which Leica M lenses are your favorites to all around? The one camera one lens motto

Also adding to this, would you think the Summicron-M would be a good choice to use for video work?

First off, I don't think this forum is meant for gearhead talk - plenty of other places for that. Second, get a camera aimed towards filmmaking instead of stills. Leica lenses are awesome but you need a great codec (or shoot raw) to get good results.

the a7s shoots ProRes 422 through external which I run through a clipster providing .dpx sequences which I conform in resolve. SO I'm not sure what you mean by "great codec"

The a7s shoots 8-bit 4:2:2 externally (4:2:0 internally), which can be recorded in Prores 422, but it doesn't make the original data any better. Whatever you're doing later on in the process gives marginal if any benefits and will never actually give you a 10-bit image. I could take an iphone video and transcode it to whatever I like, but it wouldn't change the original quality (or the lack thereof). I'd say it's a safe bet that Mr. Deakins has never shot on the a7s and can't really give you an opinion on that, but of course that's my speculation.
