Puts' latest impression on the ZM lenses

[peter_n]

My take is that he said the ZI lenses basically had the same optical performance as their Leica counterparts of equal speed, except the 35mm Biogon, which he lumped with the 35mm Summicron (4th version). In other words, they are all excellent.

I do note, however, there are no Zeiss counterparts to most of the most recent Leica offereings -- 50mm Summilux ASPH; 28mm Summicron ASPH; 75mm Summicron ASPH, ect. -- which, I believe everyone acknowledges are the standouts in the M line.

Not everyone. There are plenty who prefer the pre-aspherical lenses.
