Perspective has very little to do with the focal length of a lens.
Only chaning the POSITION of the camera relative to the subject will change
the image perspective. The focal lengh wont.
Crop the middle out of an image taken with a 35mm and you can get EXACTLY
the same image that can be made from a 50mm lens. Provided of course that
the camera position is unchanged. This is usually considered basic knowledge
for photographers.

>....or....
>
>2) A 50mm focal length is now a medium telephoto perspective, with the

>and depth of field, in the same way that on a large format camera a
>50mm focal length is a wide perspective.

Over to our host for this evening, Mr W Robb !
