[QUOTE="nickt, post: 434057, member: 4923"] As the others said, some dx lenses could work on a fx without much of noticeable problem. The image may not be up to lens spec at the corners and edges. It may depend on zoom or aperture to demonstrate a problem. The problem could be distortion at the edges or vignetting. For example a 35mm lens is 35mm whether it is a dx or fx lens. In the dx lens, corners are cut. I'm saying that figuratively and literally. If it is a dx lens, a simpler design may get the job done. The dx sensor is smaller, so the lens can be designed concentrating on the more center portion of the image that the smaller sensor will see. Put this dx lens on a fx camera or 35mm film, and we may see vignetting or just lesser quality at the edges. These lesser quality outer areas are where the dx lens was not expected to perform since a dx sensor would never capture this area. And yes, if you crop later, it should work out the same as auto dx. With auto dx, you will just get smaller files from the start since the image is pre-cropped to dx size. [/QUOTE]
