The megapixel war reloaded: Upgrading my 350D
Sep 6, 2009

With all this war against the increasingly megapixel count I have been really skeptical to upgrading my 350D to a 500D. I am happy with 8MP and I see no reason to waste my HD space with image files of 15MP of the 500D.

Basically, I just wonder how stuff works. Would I get the same IQ from the 350D sensor if I reduce the image size of the 500D from 15 to 8? I assume here that the 500D raw will still be taken with 15 and than interpolated to 8, possible image deterioration. If the SNR of the diodes of the 15MP sensor is lower could make things even worse.

ON the other hand, if the nr of photons captured by the two sensors is the same, and you don't lose IQ during the size reduction, than one could again argue that if the masses want more MP, let them have it, plus you can get access to some extra MP if you someday might need it.
