[quote=PAN F;1749848][quote=mrlazyli;1741919]I had Tokyo Simlar 50/1.5, Topcor 50/1.8, 50/2, 50/3.5 and Leotax Leonon 50/2
The other Topcor, Leonon and Fujinon 50/2 are Planar design. Very sharp indeed!
You say that the Fujinon 50/2 is a Planar design, do know anywhere were the Fujinon L lens diagrams are available?
I have a Japanese book series that introduces the LTM/M lenses (> 300 lenses)
