Please excuse me butting into the thread, but I just wanted to say that my understanding is that the focal length of a lens does not change if on a body with a crop factor--but that the increase in size of the image is from the pixels in the cropped area being enlarged to the size of a full-frame sensor, and that if one compares images from a 200mm lens on a body with a crop factor of 1.5, which gives the same field of view as a 300mm lens, and then compares those images to those taken with a 300mm prime shot on a body with full frame sensor, there would be, with everything else being equal, degradation in the images shot on cropped body with respect to those shot with a 300mm lens. I've yet to confirm this with the gear I have, but hope to do in order to compared the "apparent magnification" with the actual magnification.
