>>293916>Are full frame CCDs inherently better?No one uses full-frame CCDs anymore since Kodak ProSLR and the original Canon 1Ds.
For current CMOS sensors, per-pixel noise level is roughly inversely proportional to the area of each individual pixel. That means that at the same level of technology, a 10 megapixel Four Thirds sensor is going to be 4 times (2 stops) more noisy than a 10 megapixel full frame sensor, or equally noisy as a 40 megapixel one.
Also, full frame sensors are inherently much more expensive, but the absolute difference is gradually becoming smaller in time.
