Lens Mir-3B 3.5 / 65 review

Mir-3 is a wide-angle lens for medium format cameras such as Kiev-6S, Kiev-60, Salut and Kiev-88.
No, I didn't make a reservation. On the medium format, the FR 65 mm gives exactly the wide angle. The owner of a “native” camera lens will see in the viewfinder a picture equivalent to FR 35 for a more familiar full frame of a narrow film.
Traditionally, Mir-3 was produced with two types of mounts - for bayonet B (for Kiev-6C and -60 cameras) and B (for Salut and Kiev-88 cameras).

Mir-3 is a rather rare lens and any variants are rare. However, the B-mount variant is much less common. For some reason, there was such a bias in production, and this is not the only example.

In the review, a B-mount lens produced at the Kiev Arsenal plant in 1977. There is a quality mark on the lens barrel.

Mir-3 is a large and weighty lens. True, taking it in my hands, I personally prepare myself every time to feel the weight more than it actually is, especially in the front expanding part.

But the design of the lens is such that it has no lenses in front, except for the front, they are all concentrated in the back.

The shape of the lens is a kind of old school, it creates a respectful feeling of something old, capital, professional.

The front lens is 88 mm in diameter. It is noticeably convex, but the deep sides of the body hide it completely.
The lens has a single-layer coating of a subtle purple tint.

The focusing ring is wide enough with good knurling and is conveniently located.



The full stroke of the helicoid is about 250 degrees. The ring moves smoothly, despite the considerable age of the lens.

The diaphragm control ring is farthest from the device.

The diaphragms switch with clear clicks and stops only in the main positions.


There are 6 diaphragm petals, they are shiny, bright red in color. This color of the petals is common on Soviet medium format lenses, which is strange because the medium format was sort of the professional segment.

Mir-3B has a blinking diaphragm and it can be automatically closed, of course, only on the appropriate camera - Kiev-60, for example.
However, the design of the diaphragm drive is successful in that to close it to the operating value, the pusher does not need to be pressed, but, on the contrary, released.

On the Kiev-60, during framing, the pusher is pressed all the time, and the diaphragm is open at the same time. When the release button is pressed, the pusher is released and the diaphragm is closed to the operating value.

Thanks to this feature, the lens, being put on through an adapter on modern devices, without any problems allows you to control the aperture in manual mode. The pusher is never pressed and therefore the diaphragm is always closed to the working value, which can be changed by turning the ring.

I liked Mir-3B at work. Besides the solid design, it has a nice picture.

The lens is, how to say, responsive. Does what you want from him.

Mir-3B is a very sharp lens, and with an open aperture too.

The blur pattern is cute, but without a noticeable personality, as it seemed to me. Although, it all depends on the specific case and taste.

The bottom line is that the lens is excellent.

Should I look for Mir-3 on a modern DSLR?

I would not call it reasonable.

Firstly, the lens is rare and because of this you are asked for more for it than it can give you.

Secondly, the FF of 65 mm is not a very intelligible FF in a full frame, my taste. Not long, not short ... The role of universal lenses is now performed by standard zooms. You want something specialized from a manual lens.

In general, the Soviet photographic industry can offer you a lot of lenses that will give you the picture no worse, and will cost you money and time for searches much cheaper.

The lens is awesome though!

That's all for me, good luck!

You can use B-mount lenses on modern digital cameras. To do this, you need an adapter.
