Does size of CCD matter (besides the resolution)?

[mpenza]

saw that the CCD for the Fujifilm S602Z is bigger than the Canon G2 despite the lower resolution. Would it mean that it is capable of producing less noisy images? Most of the digital SLRs have bigger CCD sizes too.

Hard to say ley... maybe being bigger, the heat management can be better? And one thing is that it'll affect the design of the lens... I believe that a bigger CCD will need to have a longer and larger lens to achieve the same result compared to one with smaller CCD...

If memory don't fail me, a larger CCD also means the photosites are bigger, and can be spaced a little further out. Result will be less light spillage, less noise, etc.

For the same lens design and focal length, a larger CCD size will enable the manufacturer to have a smaller focal length multiplier factor as compared to other manufacturers. This means that the former will be getting an overall shorter focal length than the latter.
