Frameworkers, I am looking into mirrorless digital cameras for capturing individual still frames on a JK optical printer to then be compiled into video output. I realize that there is information out there on past implementations of DSLRs and mirrorless cameras used for digital transfers but I want a very contemporary take given the advancements in this format and what one's general concerns might be. I would also love to see examples of output from similar set ups. I realize that much of this can be gleaned from research, but my attempts so far have only yielded uncertain results (dead links, old posts, unspecified techniques). I am more interested in the consumer market of these, and don't really want to spend more than $500 on a body.
• What sensor size (considering crop factor/coverage and using existing 50mm and 75mm lenses on my JK) is optimal for capturing 16mm/S8? It seems that the mirrorless cameras have gained considerably larger sensors in the last year(s), even on the consumer level, so now certain sensors are 2x the size of a 16mm frame. JK's website references using an older Lumix and the old Sony S1 Pro, which doesn't really apply to today's market so well. • Will I likely need to extend my bellows more than 6"? Light • Consumer cameras seem to have a lowest native ISO rating of 80-200, depending on the model/brand. I'm assuming that one consideration I should take would be finding a camera/sensor with the lowest native ISO, but is there generally a massive difference in latitude between the common 80/100/160/200 CMOS sensors? • Would I need to compensate for density through lamp brightness/filters in order to capture more detail in shadows/highlights? • Alternative light sources? A Frameworks thread back in December 2010 addresses this pretty well and how the standard bulbs are only rated for 10-20 hours of use and this process being incredibly slow you could burn out your bulb before you even capture 100' of film. I am inclined towards building my own LED source but am wondering what others have come up with. I know Jaakko sells LEDs for the 103/104, but I think I can come up with something more appropriate for my specific needs. Process/Output • That same thread from Dec 2010 mentions compiling the images in an animation codec in FCP7. I have Adobe CC + access to older CS programs and Media Composer 8, so wondering what the best workflow with those resources would be. Overall I have a 103 that's controlled with a computer-based sequencer. I use Nikon enlarging lenses and a C-mount REX 4. I don't want to invest in large format (135mm/150mm) lenses at this point. I am leaning towards a Sony A5000/51000, depending on the crop factor/coverage as it has a 23.2mm x 15.4mm sensor. I'll control the digital camera as I do the Bolex, through the computer sequencer, so I need a wired remote for interfacing the shutter actuation. I realize that an older camera body might be just fine for my needs, but SDXC would be nice, especially if I want to shoot RAW. My general expectations are to have a set up sufficient for web output, but something suitable for digital projection would also be nice. I know this is a sloooooooow process and that there are likely several other considerations I've overlooked or just not researched. Any input on my specific questions or experience with similar set ups would be greatly appreciated. Thanks, Chris
