The m43 sensors aren\'t there yet, but the Panasonic 16MP sensor shows performance just about dead on the Sony 12MP sensor, which is the generation previous to the 16MP sensor and supports my assertion that the next generation of Panasonic m43 sensors will have performance comparable to the current Sony 16MP APS-C sensor and therefore entirely acceptable performance at ISO 1600 (at that point I expect current APS-C sensors to be at or above the 30dB point at ISO 3200 and FF to be hitting 30dB at ISO 6400).
So, do you think there are limits to this technological progress? If the next generation of FF sensors will have 30dB SNR at ISO 6400, will the one after that reach the same SNR at ISO 12800? and the next one at ISO 25600?
There certainly are physical limits, I just don\'t think that we\'re hitting them yet, or even close. We certainly aren\'t even close to the process limits (which are in the 10nm range these days, sensor wells are 3 orders of magnitude larger).
Frankly people were saying we were near the limits back in the 12MP FF sensor days. We weren\'t and we aren\'t now. Once we see 2-3 sensor generations without any significant changes then we\'ll be at the limits.
