As technology develops 'other things are not equal'.to quote a review I saw recently from a well know pro:All else being equal, the more pixels you put on a sensor the smaller they are, and the smaller they are the noisier they are. However, all is rarely equal. The 7D uses a new “gapless” lens system over the pixels which increases their light collection efficiency and so reduces noise. Upgraded electronics (including the dual Digic IV processors in the 7D) can also reduce noise. So the question is whether the increased pixel count of the 7D makes it noisier than its predecessors (40D/50D). I think I can say that no, it doesn’t.Comparing the 7D with a full frame or 1.3 cropper costing almost three times as much is not a fair or relevant comparison IMO. For example the new 1D4 has been given a RRP of something around £4500 I believe so it is obvious that it will have advantages over the 7D.I am still shooting with the humble 40D but from everything I have read noise levels (especially at high ISO) from the 18mp 7D is as good if not better than the 10mp 40D - for this Canon should be commended IMO.</blockquote>
