Some of us have been using ultra-wides for years, I've owned my A16/2.8 Fisheye since Feb 1987 for instance so the crop factor can be a style stifling limitation. I only acquired my first lens longer than 135mm a few years back and those I seldom use now with the crop factor in play. >From what I've read signal to noise performance per pixel area is pretty much >close to theory at this point, beyond applying micro-cryogenic cooling systems >I don't believe that there are big advances to come on the hardware side. >Noise reduction algorithms will improve I expect but nothing comes for free or >without their own set of problems.
