Carl Zeiss Jena Tessar 4,5/300 Review
Carl Zeiss Jena Tessar 4,5/300 is a telephoto lens for large format cameras. Covered image circle 24x30 cm. Installed on pavilion cameras and used for portraits. On the large format is a great portrait lens.
Now craftsmens used it in the construction of makeshift home theater and video projectors, as it is a great image circle, and thus can project a screen of laptop or tablet to the big screen or a wall. Why not.
But in this review, I would like to use it for its intended purpose as a photographic lens, but not on a large format, on the camera with APS-C sensors. What came of it, read on.

Monuting Carl Zeiss Jena Tessar 4,5/300 on DSLR Camera
I was interested to install such a monster on DSLR camera and see how it will behave on the camera with APS-C sensor.
I have a special focusing helicoid, for mounting large format lenses on SLR cameras. But mount this lens it was not so simple.
M88 mounting thread is quite rare. Included with the lens was some kind of adapter with M88 thread to M70. My helicoid has a thread M60. Therefore, in order to attach it to my helicoid I needed another adapter M70-M60, which I asked to carve a friend's turner.
Adapters for mounting Carl Zeiss Jena Tessar 4,5/300 on the helicoid.
The problem with mounting decided. Now you need to compensate for the long flange distance. It took me to this big extension ring for medium format and KP88/N adapter.
That's it looks at the Nikon D7000.
According to my calculations the whole construction, with the exception of the camera, weighs about 1.6 kg.
Carl Zeiss Jena Tessar 4,5/300 Example Photos
Unfortunately due to lack of time, I shot them only once, on the way to home. A full test with good examples do not make.
All examples are taken at wide-open aperture on Nikon D3100, RAW export, no post-processing.
Carl Zeiss Jena Tessar 4,5/300 Sharpness
The lens shows good sharpness for its focal length and aperture. But still there is that it is for large format. The resolution is not as high,
Because I tried to use only Tair-3 4.5/300, on the feeling it seemed a little sharper than Carl Zeiss Jena Tessar 4,5/300, but the gap is small.
Carl Zeiss Jena Tessar 4,5/300 Character and Bokeh
The lens has a nice character and bokeh.
Carl Zeiss Jena Tessar 4,5/300 Contrast and Color Rendering
The lens has a single-layer coating. Due to its optical design it has a good contrast. Stray light is not afraid.
Compared with Tair-3 4.5/300, Carl Zeiss Jena Tessar 4,5/300 have better contrast.
I shot this lens somewhere in half an hour while walking home. Over the half an hour, my hand was so tired that I did not photograph well compete dumbbell. Yes, ease of use it is clearly inferior small format lenses. But it has an interesting character. It will be an opportunity to take pictures of these portraits of the lens.
