The most interesting low cost sensor out there for me is the new Blackmagic micro cinema.. global shutter.. all our motion cadencemo issues gone right? With a speed booster, it could be a 1.7x crop of "full frame", which is really a stills more than movie film thing, right?.. APSC size is about the same as 35mm movie film, all the apeture/field conventions translate straight across. If the BM micro cinema had the the lowlight of the A7s.. the perfect cheap sensor.. Global shutter, A7s lowlight, 4k, log, raw, hdmi out - speedbooster built into camera with auto calibration, wifi, pre cognitive auto focus logic.. what else do we want? All in an NX500 sized body please, $450 w/o lens And a half sized version built into a drone.
