Are all 1/2.3 sensors created equal? In the world of DSLRs there are plenty of cameras at different levels in the market which share the same sensors, differing in other specs - speed, controls etc. Also there are some cameras from different manufacturers which use the same - usually Sony - sensors (Nikon D7000, Pentax K5 and so on).
When we get down into the world of tiny sensors there's often more differentiation - lens quality and range, manual controls etc. Are some sensors better than others in this world where prices vary by factors of close to 10 between the top and bottom models?
