This Meyer Optik Gorlitz 300mm F4 lens is a telephoto lens with a manual focus, designed for use with Pentax 6 & Kiev 60 cameras. With a suitable adapter can be used with a wide variety of modern cameras. Covers 6x6 image area. Can be used on 35mm cameras such as Sony E mount. I have an adapter for this mount available as a separate auction.
The 19-blade aperture is unique making it virtually circular. See pictures. Bokeh is beautiful.
Added a few more picture. No fungus on internal lenses. Just a very small area on edge of front and rear elements that will not affect image quality.
Heavy lens at 2.15kg so a suitable heavy duty tripod is recommended.
Case supplied.
