Got this off from kenrockwell.
I cannot really make head or tail of what he is saying, but it seems to be correct yet uncorrect at the same time.
1st Paragraph seems a half-truth, if he would clarify it.
2nd Paragraph seems to be wrong?
3rd Paragraph is to complex to be understood unless I dissect the statement.
For the record though, if there are any newbies reading this, don't get confused. Just play around with your lenses and you'll get pretty much used to them. Once practical is easy, the theory part becomes much easier to understand, not the other way around.Perspective depends only on your position. It has nothing to do with your lens.
Shorter or longer lenses don't change perspective, they just make framing tighter or looser.
Different lenses require you to move closer or farther way to get the framing you want, but it's the change in position that alters perspective, not the lens.
