ERA-13 russian high resolution lens

f4.5/150mm once used for chipmaking, here used fully open

That's pretty sharp, Klaus. And useful DOF wide open.   A rare lens?

Hardly seen sold, but actually not many were made. But I need to issue a warning,
the lens + mount is around 2.5 kilograms, so over5 lbs.

The images are not only sharp but also very rich in color.  2.5kg would be lightweight for a chip-making lens maybe?

Arigato domo Akira! Yes, light for a chipmaking lens, but heavy for my arm taking photos for hours outside handheld... ;-)
