Lens Mir-38B 3.5/65 review

Mir-38 is a wide-angle lens for medium format cameras such as Kyiv-6S, Kyiv-60, Salyut and Kyiv-88.

It is wide angle for medium format. On a narrow film, things are a little different, but more on that later.

Mir-38 was produced with two types of mounts - for bayonet B (for Kyiv-6S and -60 cameras) and B (for Salyut and Kyiv-88 cameras).

Today, Mir-38 is relatively rare. But, this applies to many samples of medium format equipment, it was initially released less. However, this lens cannot be called rare either, there are always 1-2 offers.

According to my subjective observations, options for bayonet B and C are approximately the same.

It is believed that Mir-38 replaced Mir-3 (I have a review of Mir-3 for B mount).

The aperture and FR of the lenses are the same, the optical design is similar, but not identical. Mir-38 is lighter and more compact. The resolution of Mir-38 center/edge 42/20 lines/mm is greater than that of Mir-3 - 40/14.

In one source I saw the idea that Mir-38 is a simplified version of Mir-3. I can't remember where I saw it and how it is justified.

In the review, a lens with a B mount, produced at the Kiev Arsenal plant in 1986 with the number 863007. Quality mark on the lens barrel.

Mir-38B is a large and weighty lens, although it is no larger than modern options for full-frame DSLRs.

The shape of the lens is cylindrical.

The lens has a single-layer coating with a barely noticeable greenish tint. When looking at the transmitting lens, it seems that it is tinted. Looks very interesting.

The focus 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.

The aperture control ring is closest to the device.

Apertures switch with clear clicks and with stops in the main and intermediate positions.

There are 6 aperture blades, they are gray and rather shiny.

Mir-38B has a blinking aperture and you can automatically close it, of course, only on the corresponding camera - Kyiv-60, for example.

However, the design of the diaphragm drive is successful in that to close it to the working value, the pusher must not be pressed, but, on the contrary, released.

On the Kyiv-60 camera, during framing, the pusher is pressed all the time, while the diaphragm is open. While pressing the shutter button, the pusher is released and the aperture is covered to the working value.

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

My relationship with Mir-38B did not work out.

Some lenses seem to be responsive. What you expect from him - he draws. I liked Mir-3B. He is responsive. But I won’t say this about Mir-38B.

Although it is possible, the whole thing is in my particular instance. Of course, you can not criticize the brand of the lens by one representative.

However. I even wore Mir-38B "for a walk" three times. Alas, this is a rare occurrence. As a rule, it is physically impossible to devote so much time to the lens, unfortunately.

My Mir-38B gives a good contrast. On the open it seemed to me that a little extra softit.

I didn't like the blur pattern. IMHO - the blur lacks a smooth transition. I see this in my photos and in others on the web. Although, the reviews are mostly positive. Well, the taste and color ....

Is it worth looking for Mir-38B for a modern SLR?

My opinion is no. Although the Mir-38B through an adapter will fit almost any modern device with interchangeable lenses.

On a full-frame SLR Mir-38B will give a picture corresponding to its 65 mm FR, i.e. will be something between a normal lens and a moderate telephoto lens.

On the crop - from 100 to 130 mm EGF in the equivalent of 35 mm film. It's quite a telephoto. Large only for cropped devices.

But the fact is that FR at 65 mm is not a very intelligible FR at full frame for my taste. Not long, not short... F3.5 - comparatively dark.

The role of universal lenses is now performed by regular zooms. From a manual lens I want something more specialized.

If you have a Nikon SLR and want a lens with a FR of less than 100 mm (that is, the excellent Kaleinar-5N 2,8 / 100 for some reason does not fit), then the Mir-38B may be an option. Although, I think it's better to look for Mir-3B in this case.

That's all I have
