making some order in the cabinet, I've re-found a lens arrived many years ago along with my Kiev-10 camera.
It is very compact, heavy and well-built. It bears the serial number 71026.
Looking through the lens once mounted it on the camera, it gives a "yellowish" vision, as expected from lenses with lanthanium glass elements, like the well-known Pancolar f:1,4 of the Pentacon Super.
The diaphragm transmission is a little sticky, due to the old lubricants, but I will send it to be fixed.
Does anyone be so kind to give me more info re. this lens?
