Cool. I've thought about this a lot, just because the UX of now cheap older cameras tends to be very good, for me at least, and the UX of the low end digital tends to be very eh. > $1000 bodies, it's a different story of course. It isn't exactly clear what I meant by UX; With my Minolta SRT 201, I can see Aperture and Shutter speed at a glance, modify them with a quick, dedicated, dial twist, have a distance scale on the lens, and look through a large, somewhat bright viewfinder (Later Minolta viewfinders are noticeably brighter though). The mirrorless experience on the low end really can't compete. Cheap DSLRs are closer, but with shit viewfinders, and I hate the Canon top screen/dial system, and harder to adapt old lenses.<p>This means you can use the Shutter speed dial, the combo shutter button is a good idea that I did not think of at all (I always was thinking you'd use two buttons, one to put the digital side in BULB, then the actual shutter, cause I'm dumb). On the other hand, if I had a functional NEX-5, I don't think I would have the heart to do it, and 38mm is maybe a little long for m4/3 general purpose. I like ~40mm on APS-C.<p>Really I also kinda wanted to write the sensor driver, but sourcing decent sized image sensors seems impossible. I know some people who could maybe get me cell phone size samples, but m4/3? I don't even know how, and I'd need a decent datasheet too.
