Not 100% equivalent, but from what I’ve heard, this can be an issue when using full frame lenses on a crop sensor DSLR. The sensor gets everything from a smaller part of the lens, so defects that don’t show on a 35mm equivalent sensor can show at APS-C.
- CarVac 7y agoWhen you use a full-frame lens on a crop sensor: * Vignetting always improves * First-order distortion improves, second-order distortion sometimes gets worse. * Corner sharpness usually improves, unless midway out on the frame was the weakest performance on full frame. * Center sharpness (image-scale) drops due to the additional enlargement. * Lateral chromatic aberration generally doesn't get significantly better or worse. * Longitudinal chromatic aberration becomes more visible because of the additional enlargement.
