RE: 31/1.8 limited: moulded glass?

2001-04-24 Thread Denis Klimovich

Moulded glass means "real" asphericals, right? Not the hybrid
glass-plus-resin?
If what I am saying here is right, what an impressive beast !

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 Pål, the 31mm will ruin me... :-)
