With the arrival of the Summar in yesterday's mail, I now have all the 50mm vintage Leica lenses I've wanted:
Elmar f3.5
Elmar f2.8
Summar f2
Summitar f2
Summarit f1.5
col. Summicron f2
'69-79 Summicron f2
A 35mm Summaron, a 90mm Elmar, and a 135mm Hektar complete my collection of Leica glass.
I also have some Canon (85f2, 100f3.5), FSU (I-10, J8, J3, J12) and CV lenses (25, 35f2.5, 50f2.5)
