The Meyer-Optik Görlitz Primotar 135 mm f/ 3.5 is a telephoto prime lens for 35 mm SLR cameras with the M42 screw mount.
This is a very rare lens whose characteristics and descriptions are hard to find in the Internet.
Initially the Meyer-Optik Görlitz Primotar 135 mm f/3.5 is designed for the 6х9 frame format, i. e. on a 35mm camera only the central part of the image is used, which results in surprisingly inconsiderable decline in quality towards the frame edge.
The present graphs show extremely low chromatic aberration at all apertures and maximum resolution at f/11 ( at f/8 it is more than just acceptable). I am sorry for the quality of the graphs. I made them on my own to determine working apertures of this lens.
The Nikon D9 was used for the test shooting and the resolution of the Meyer-Optik Görlitz Primotar 135 mm f/ 3.5 was calculated for its sensor.
