The f2 version of the popular and well thought of  50mm standard lens for full frame 35mm cameras.

This example is in very good condition with smooth focusing and precise diaphragm control. Apart from the expected specks of dust in a lens of this age the optics are clear and free of fungus and haze.

The images included are pairs, with the first in each pair taken at f2 and the second at f8. These were taken on a Pentax K1 MK2 and have received no after treatment apart from adjustment of brightness to achieve roughly similar image density.
