A Question about Camera Noise
After reading a recent post here, " Canon 7D and 1D Mark IV Metering posted 09-15-2010" I began to wonder about the apparent advantage some cameras have over others in regard to use of high ISO's. Artie clarifies in this post that the 7D and 1DMkIV need considerably more light than a 40D or 50D in a low light condition.
If a 7D or a 1DMkIV need more light than a 40D or 50D in low light conditions then if all other things are the same, isn't some of the high ISO advantage of the 7D and 1DMkIV lost? Perhaps most of the advantage.
