Nope, it has a Tessar formula and it is a 5cm lens Wink

Obviously an old lens. Therefore rather F11 (not the lens but the capturing).

5cm f/3.5 is correct. It is a rangefinder lens in m39 mount. None of the mentioned lenses is correct. Very Happy

I have only few range finder lenses, while you have the most bizzarre range finder lenses - that's not fair (!)

Ive aimed against none Leica m39 RF lenses for a while. I think it is interesting to collect and compare them Wink
I am kind of surprised about how many different brands and versions there are made!

I bought the Topcor because of the fascinating design. It looks cool on the A7 and performs pretty well too Very Happy
