I might add that a 65mm compares to a 16mm, and a 75mm compares to a 19mm. PKM-25 is exactly right, you really do not realize just how wide LF lenses are if you use something like 3x to compare them. Wide angle has never been a major problem with LF, unlike sLR's that require a retrofocus design to go much shorter than 35mm.

On the long end is where you get into problems with LF as lenses quickly become bulky and very heavy.
