yeah, sure - by straight optical physics
but the actual effect is a seemingly longer reach w/
a given focal length on a smaller "film gate" exactly
like everyone is so happy w/ when putting a tele onto
their StarKist w/ its less than 24x36 sensor. The end
result (granted, it is merely a *cropping factor* like
on would get w/ an enlarger) is an apparently longer
lens - period - ... and that's all that matters.
