Is there going to be a viable way to use older cine glass (like say Zeiss Standard MII's, Cooke Speed Panchro S2/3's or a Cooke 20-100mm Zoom, which cover a smaller image circle) with the upcoming Epic S35 & Scarlet S35 with its lager sensor? Meaning, will there be either a specific window or cropped mode of some sort to deal with this? Or, is this basically as simple as using custom framing guides and/or a mask that one could generate and set up in the viewfinder to use just the cropped portion of the sensor which doesn't vignette or porthole? If so, any foreseeable issues in post with the above method?
p.s: And I realize one wouldn't get all that full 4.5k oversampling goodness...
... something called "RED One Classic S35 mode" or something???
