Mostly depends on what you mean. Many of the better SLRs are showing how poor the lenses are and are out-resolving the lenses.
Lower end SLRs crop out the center of the image, so tend to actually improve the effective lens quality. |
Sort of--cropped sensors only use the center or "sweet spot" of the lens. But their "pixel pitch" is smaller (compare the 10MB 400D to the 1DMII or 5D) so the center of the lens has to be sharper. In other words, the circle of confusion of a given lens covers more pixels on a cropped sensor camera, assuming the number of pixels are the same on both sensors. |
Yup, but, as you mentioned, most lenses are significantly better in the center than at the edges, cropped sensors have an advantage over higher resolution, full frame sensors. Pixel pitch matters, but I don't see issues due to pixel pitch visibly in my images, but I do see how soft something like a 17-40 F4L is at the edges on a full frame sensor.
