Hi Paul,

Sorry I know you sent this a while ago but I've just got around to catching
up!  

Had a quick scan of the ensuing thread but, as far as I could see, nobody
mentioned signal:noise ratio in relation to pixel size.  In a nutshell, the
larger the pixel, the better the image quality as a greater signal can pass
through it (within reason I suppose!).  The smaller the pixels within a
given chip, theoretically the quality deteriorates as the noise:signal ratio
is higher.

Take a look at this link posted a while ago (thanks Ian...):

Best wishes,
