Lens Test: Meyer-Optik Görlitz Orestegor 200mm f/4

Photographed with a 200mm f/4 Meyer-Optik Orestegor lens on a Canon EOS 30D camera.
The Meyer-Optik Görlitz Orestegor 200mm f/4 is a preset manual lens, with continuous aperture, which can be limited with a special preset ring. It has 15 blades which close and open very smoothly in the range f/4-f/22. The focus throw is very long.
It is all metal and built like a tank. Enthusiasts report difficulty in finding one. Mine just happened to be in a little Zenit-E kit which I bought for the Helios lens. To get the 15-blade Orestegor and a set of three extension tubes was something of a bonus.
