Good point.
I suppose you want as many pixels are you can before noise starts to reduce image quality in shadows and dim areas.
Although I must admit I took some 40D shots with my TEC110 (wildlife) and also a 5D Mk ii. The 5D images were not as good as I expected them to be. The 40D images were not far behind at all. Hardly conclusive as it was only several images though.
Sometimes a crop sensor is better in that it gives that extra zoom factor
but if you can use a full frame and it will shoot also in smaller format then you have the best of both.
Have you experienced much an improvement in images from jumping up a lot in mp?
Greg.
