Rather a noob question here: on a DSLR with a crop factor, the thing is that only a certain amount of the image gets to the sensor, except on lenses designed specifically for a cropped sensor, right?

Well, what about the viewfinder and mirror? Are these adjusted, or does one see more than the sensor does? I would think that it would be adjusted, but I'm just checking to be sure.

Pic unrelated; it was a useful chart someone posted here a while back.

Most DSLR viewfinders offer the same viewing angle as film camera's The Viewfinder shows 92% of what The camera actually takes a picture of.

So they are corrected for the sensor size in DSLR's.

what you see is very close to what the camera takes a pic of, No matter the lens.

Crop factor will affect the performance of the lens that you use. If a lens is your 50mm prime, then it will only work at 50mm for a film SLR. If you use a digital SLR with a crop factor, then multiply the crop factor by the length of the lens and you will have the effective length. So, your 50mm will work as a 75mm on a dSLR with 1.5x crop factor. It's very important to note this as 75mm is considerably longer than 50mm. This will also explain why your wide lens doens't feel that wide. It's because it isn't when on a digital body.

I know; I was asking what effect (if any) it had on the viewfinder, which the previous poster answered.
