I especially like the 2X cropped format on the X at 8 FPS for wildlife and sports shooting. Makes a 400F2.8 into an 800F2.8 (except for the DOF).



No it doesn't. You get exactly the same photo in the non-cropped format, except that it has extra stuff around the would-be-cropped area. All that this mode gains is speed, at the expense of a wider field of view. NO extra magnification whatsoever.
