A620 vs A630, A640: different sensor?
I need to replace my broken A620. Reviews and galleries for the A630,
A640 and A710IS show a significant difference in noise; my A620 is about 2x noisier. Pics taken with an A630 or A640 at ISO400 compare with my A620 at ISO200, noise-wise; same with A630/A640@ISO800 vs. A620@ISO400 (equally unusable!) Any input? Are these different sensors? How about the A710IS? Thanks. |

A620 vs A630, A640: different sensor?
Just a comment, the A640 is compatible with PSRemote, which is useful for making time lapse movies, whereas the A630 is not. wrote: I need to replace my broken A620.
