Structure: six lenses in four groups (Planar)
Vision angle: ~ 18 degrees on APS
Format: APS-C (native), covers APS
Maximum Aperture: F / 1.8
Resolution (center / edge): 75/40 lines / mm (projection), about 33/30 lines / mm (photographic, in comparison with Jupiter-11, it is much less sharp)
Features: There is no focusing mechanism or aperture. It has a similar twin in name, but everything else twin brother - KO-120M in a new building with a GOST name. Do not confuse!
The weight: 1100 (the main difference from KO-120M with the same name is twice as much weight).
Years of production: the end of the 80s - the 90s (produced only at the MMZ, aka BelOMO).
Appearance and ergonomics
The 35KP-1.8 / 120 itself is just a bare lens unit. The lens is very large and heavy, has a huge front lens. All lenses are enlightened (single-layer enlightenment).
The lens is assembled quite well - honest slotted nuts sitting on locking screws. The walls of the lens block are metallic, thick. Construct "foolproof" - for centuries.
For use on a modern camera, you must at least make a focuser. You can take focusers from an evil type of dead 500/8 lenses as the basis, or you can make some kind of temporary focuser yourself, as it was once done for KO-120M.
A serious obstacle is weight - more than a kilogram. Not every photographer can easily be controlled by such a carcass as this 35KP. A lot of weight requires the right focuser for the lens.
It may be difficult to find a cover for such a carcass. So, it’s incredible, but one of the plastic covers for three-liter cans ideally suited him - a note to the hostess! ;)
The working distance of the lens is very large, because it can be planted on any modern camera.
The lens has a famous circuit - this huge 120 / 1.8 planar. Actually, all the pros and cons of the lens follow from this.
- Absolutely huge for a focal length of 120 mm aperture allows you to achieve miserable depth of field and generously blur the background, which is good for portraits;
- Enlightenment of the lens does not distort color reproduction unlike Triplet 2.8 / 78 и KO-120Mwhose colors are slightly warm.
- The lens has a flat field, unlike aplanat KO-120M - this makes it more versatile.
- The lens just has a great planar drawing!
- Enlightenment provides a good contrast, although it is very difficult for it against backlight (see minuses).
- Vignetting is not noticed.
- The sharpness of the lens, especially at close distances - is very weak, it feels like this 35KP is corrected for infinity. KO-120M has generally much better sharpness.
- The lens is very chromate, again more than KO-120M - I will call this the most important drawback;
- The large front lens collects glare and brings down contrast without a hood.
In general, the lens for shooting is definitely interesting - it has a beautiful picture, not the worst sharpness for such aperture with such a focal length. In some ways he loses KO-120M, in something he is much better. Better to have both of these lenses :)

The names of the lenses correspond to their exact spelling on the body.
35KP-1.8 / 120 is another lens that requires its owner to tinker with creating a focuser. However, if the owner deigns, he will certainly be awarded an excellent fast lens with an excellent design!
