AAhh, these limiteds. IMO, this is one of the most peculiar lens series ever released. PDML'ers have speculated _a_lot_ over the focal lenghts; everything from complex mathematical models to marketing tricks has been suggested. Mathematically, the 43mm is the correct focal width for a normal lens covering a 36x24mm negative. If there's mathematical reasoning behind 77mm and 31mm, it's beyond me... Maybe it's just a new standard of naming accuracy. I often read lens tests where measured focal length differs from the number on the barrel. I know one thing for sure; just like P�l, the 31mm will ruin me... :-) Jostein > -----Original Message----- > From: Peter Smith [mailto:[EMAIL PROTECTED]] > > What is it with these limited lenses?
