Leica M9 + Leica Elmar 135/4 (1960s Chrome)
Model - Ana
The Leica Elmar 135mm must be one of the best value for money Leica lenses available and is close to being on a par with the little CV Nokton 40/1.4 in terms of cheapest lenses for Leica cameras.
It's 135mm yet 39mm filter size and very lightweight. Easy to focus up close without magnifier at f4... less so at a distance.
