Carl Zeiss Jena DDR Sonnar 3,5/135 Review
Carl Zeiss Jena DDR Sonnar 3,5/135 is a telephoto lens for 35mm cameras. The lens is an improved modification of the Carl Zeiss Jena Sonnar 135mm f4. Differs from its predecessor smaller in size, and speed and "Zebra" barrel design. Produced for M42 and bayonet Exacta.
My copy is released between 1970 and 1975, as evidenced by the serial number 9432400. Has single coating. The optical design — classic Sonnar, 4 elements in 3 groups. I mount it on a Nikon D3100 camera with adapter M42-Nikon, while focusing is possible at a distance of 8 meters. That ASP/C cameras allows you to take a half-length portrait. To achieve infinity, the lens needs to adapt.

Sonnar 3,5/135 Handling and Mechanics
The lens has an interesting constructive different from modern ones. Black metal barrel, focusing ring is not rubberized, instead front part of barrel have thin ring "Zebra", which can be focusing.
The same ring on aperture control. On the camera, looks stylish, yet modern design comfortable and convenient.
As mentioned above, the lens has a focusing ring "Zebra". Despite the fact that it is narrow focusing is convenient. Helicoid rotates on 320 degrees, so you can easily catch the sharpness.
Wherein the front element extends 2.5 cm.
The front element is not rotating.

Sonnar 3,5/135 Contrast and Color Render
The lens has a good contrast. Stable to strong side light.
Backlight still afraid.
Example backlit from window But even in backlit behaves with dignity, turning into a kind of artistic flare charm. I did not feel uncomfortable having to shoot them in the sun.
I write this review after only 2 weeks of use. My copy substantially seedy: under the front of the lens there is a small fungus, the diaphragm sticks, carving a filter murdered, body worn.
But despite all this, the lens shows good results. It is convenient to shoot, the photos are wonderful.
Will be free time, and I will repair it and adapt for Nikon F.
