I agree that if you can get close, you can use higher ISO's as noise is less significant.Although the 50D may be slightly worse for noise than the 40D on 100% crops, the extra megapixels would surely make the noise less significant on a composition that filled the viewfinder (ie. no cropping).Also on a cropped image, the extra megapixels would allow you to make a larger print (although you may have a little bit more noise).</blockquote>
