I forgot to say congratulations on your choice of camera. You are in fact ahead of me as I have the 510 and probably will not upgrade to the 520 as the 510 is so good, easily ahead of myself. Perhaps I will weaken when the 530 comes out.

I am surprised by your comments on the noise as I do not regard the 510 as a noisy camera, BTW I believe that all the noise comes from the various moving parts flapping around. However they have pushed up the frame rate from 3 to 3.5 per sec and this may well have increased the speed of those moving parts.

[edit] I believe that some DSLRs do have a quiet mode and achieve this by reducing the frame rate[/edit]

Is the noise the same when using live view?
