Effect of megapixels on print size

No, no, you're missing the point.

The crop factor changes how much of the lens is captured. The crop factor does not change the focal length. Therefore the rule of 1/focal length therefore remains the same.

Does that make sense?

To all of those who replied: Thank you very much.

I was afraid the problem would be the lens. Now I'm sure.

DocFrankestein: Yes, the camera ships with an 18-55mm lens. What I meant is that I attached a lens I had from my previous EOS camera, a 75-300 USM.

I'll try taking pictures with a tripod and/or with fast shutter speeds (1/500). I'll also try getting a faster lens such as the EF 135mm f/2L.

BTW, is it a rule (or technical issue) that zoom lenses are slower than fixed focal length lenses? Most fast lenses I have seen have fixed focal lengths...

Thank you again
