In short
Spiratone Tc 1:2.8 f=135mm Japan - a short telephoto from the film era of the 50s, very compact. Quite rare. Uses T/T2-mount interchangeable shank system. Optically has problems. The Spiratone Tc 1:2.8 f=135mm Japan is often called a preset lens (with the ability to preset the aperture).

Assembly, control, focus
Spiratone Tc 1:2.8 f=135mm Japan made with high quality. All rings are metal. The lens uses a zebra design - the edges of the focusing ring are black and white. There is a chrome insert between the aperture setting and preset rings.
The focus ring rotates approximately 315 degrees (almost a full rotation). During focusing, the front lens (along with the filter threads) moves forward, but does not rotate.
On the body there is a scale for focusing distance in meters and feet and a DOF scale.
Focus Shift (shift focus, changing the focus distance due to iris) is missing.
Spiratone Tc 1:2.8 f=135mm Japan has a slight 'Focus Breathing' effect (changing the viewing angle while focusing). When focusing towards the MDF, the viewing angle decreases.
Hard stop (hard infinity mechanical stop) for fast and accurate focusing under any temperature operating conditions (possibly depends on the shank).
Focus peaking with Spiratone Tc 1:2.8 f=135mm Japan and Sony α7 III, Sony a3500 и Sony NEX-6 works well at F / 2.8.

Sample photos (Full Frame)
The pictures in the gallery were taken with a camera Canon EOS 5D (Full Frame, 13 MP), which has already become a “digital classic”. A 3D printed adapter was used T2-mount -> Canon EF.
Original RAW photos (Canon '.CR2') can be download / watch this link (30 photos, Google Drive gallery). I bought Spiratone Tc 1:2.8 f=135mm Japan for one photo project, but due to its image quality it was replaced by LEITZ CANADA SUMMICRON-R 1:2/90.

Results
Spiratone Tc 1:2.8 f=135mm Japan is another vintage 135 with its own advantages and disadvantages. Very compact (short), 16 aperture blades, but mediocre enlightenment and resolution at F/2.8 spoils the overall impression of the lens. For budget 135-tweaks, I have the same result: inexpensive MS Jupiter-37A 135 / 3.5 is one of the best solutions.
10 main advantages
- quality assembly
- very compact dimensions (the lens is only 79 mm long)
- interchangeable shank system allows you to use the lens through matching adapter on a large number of DSLR and mirrorless cameras
- Stylish zebra design with chrome insert between aperture setting and preset rings
- convenient focusing ring with a very large pitch
- sixteen aperture blades
- the ability to smoothly adjust the aperture, installation ring and aperture preset
- good resolution at closed apertures
- easy to find shanks for T/T2-mount for popular DSLR and mirrorless systems
- beautiful bokeh
10 main disadvantages
- large MDF (as much as 170 centimeters, for example, MS Jupiter-37A 135 / 3.5 MDF only 120 centimeters)
- Spiratone Tc coating is not the best quality
- poorly defined diaphragm clicks
- a hood that is screwed into the thread of the front filter must be used
- The aperture ring does not have rotation indicators
- shank for T/T2-mount increases the size and weight of the lens, especially for mirrorless cameras
- Lens bevels are poorly blackened
- problems when working in back and side light, significant loss of contrast
- strong spherochromatism
- mediocre resolution at F/2.8

Thanks for the look, Arkady!
A couple of times, I lost the lens one by one in terms of design and parameters, as well as other names. That one is called Sankor and Senkor and has a landing strip of M42 and a white metal tire on the front. According to optical characteristics, this is how it is, guidance in looking around. Decent sharpness appeared even better when the aperture was closed to 5,6.
The whole advantage of such frames is their zebra-type design and multi-lamella diaphragm, and nothing more.
In the 50-70s there were a lot of different so-called brands that “released” lenses. 135 just iced without letting go. Tsikavo, now in the era of mirrorless cameras we will get to the same point. China shows butt))
