No, you would crop - just like you said. But the working professional (most of the time) does not have the time to crop his or her images to the desired "focal length". When sports photographers are working on deadline, their editors are not going to crop their images to get added reach - It wastes precious time. For many pros, getting the (great) shot right out of the camera is paramount.


But, I know what you mean.

Good question. But I'll try to provide an answer. Sports Illustrated owns too copies. A $240,000 investment in optics? [H]


James Jannard, founder of Oakley and RED Digital Cinema owns a copy as well. Canon Professional Services owns one too.
