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

The lens is cylindrical in shape.

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

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.

The diaphragm control ring is closest to the device.

The diaphragms 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 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.
