Take a 50mm lens, Now lets say it can mount on Medium Format 35mm film And a DSLR (with 1.5x crop factor)
that 50mm focal length hasn't changed, and neither have the properties that go with the lens (DOF being the big one), All thats changed is the size of the sensor behind the lens.
So on Medium format, you have a large sensor that the picture is projected onto. The DOF is still say a foot deep, but the size of the sensor means you see more. on 35mm film, the size is a bit smaller, so although the DOF hasn't changed, we see less of the picture because only part of the projected image is hitting the sensor the DSLR (1.5x crop) Is now an even smaller sensor, so it gets an even smaller view of what the 50mm is projecting.
Thats simple enough, but when viewing prints, you can always blow them up to sizes that have little reference to the original sensor size. So comparing the same size "Prints" afterwards, it appears the 1.5x crop is more "zoomed in". So when crop factors are taken into account, they only look at the equivalent focal length on 35mm film (Because it is an easy to understand standard)
