Just curious if anyone knows the answer to the following questions I have been thinking about lately. For a significant improvement in the u4/3 sensor, is it specificallly a sensor design issue/limitation or can a processor developed by Olympus or Panasonic make a DR improvement by 2-3 steps to bridge it to a NEX level. I don't believe it's the size of the sensor (slightly smaller size then the NEX) that is handicapping it. Just curious if it's something Olympus might be able to do independantly or if they are tied to an improved sensor design by the manufacturer to make any gains in DR. Also, the Fovean sensor in SD1 doesn't require an anti-alias filter to control moire.. does anyone know such a feat could be done with the u43s platform in the future. If the u43 sensor had a significant improvement in DR and a super weak or lack of aa filter to improvement ooc raw/jpg sharpness, it would easily be the system to have now that the slower focusing aspect has been addressed. If they'd do such a thing in the PRO model, I'd put my deposit and preorder down immediately.
