Gentlemen,
I've a question for you. Some Leica M and R lenses have a number
engraved
onto the focusing scale (00, 16, 22, 55 and so on), after the m/ft
symbol.
Which is the meaning of these numbers? Can you help me?
It's the deviation of actual focal length from nominal. The
deviation is common among all manufacturers, Leitz was unique in
telling us what the deviation is. 00 is obviously no deviation, 16
is 1.6mm longer (i.e., a "50mm" marked 16 is actually 51.5mm).
