An over simplified answer. Were it so why would manufactures make so many
different lens focal lengths?
The answer is correct from a technical stand point, but like many things
practical issues invade reason.

Actually, it will not make any deifference at all. Lens focal length
has nothing to do with perspective. In fact perspective wasn't even
invintet until railroads became popular. There is no such thing as a
telephoto/wide angle look. I just looks like there is a telephoto/
wideangle look and if you really knew how to look, it wouldn't look
like there is a telephoto/wideangle to look at in the first place.
This can be proven by always using a 7mm lens (any format) and adding
a twelve foot post to your enlarger. You do have to protect your
wideangle prints from nose gease because the proper viewing distance
is focal length times magnification. This does mean the proper viewing
distance for an 8X10inch print from a full from a 35mm camera equiped
with a 500mm lens is eighty inches. Everyone know all this and in fact
is a given on at least one news list.

Objects in the mirror
are really not closer than they apear
so always burn out
when in reverse gear.

Heh heh heh......
