"Will the FF image appear as if it was shot with a 1.3 crop at 13.3 megapixel in terms of image size?"
Allow me to try to re-phrase the question, is it the same questions as yours?
- We print both images at 5x7 inches. Disregarding print resolution, PPI (or DPI). That is, we print both at whatever PPI/DPI prints full frame, just filling, the 7 inches. Will the subject bird that measures 4 inches on the 1D print also measure 4 inches on the 5D print?
