20 mm / F3.5 – MIR 20

20 mm / F3.5 – MIR 20

  • Focal length: 20 mm
  • Aperture: F3.5
  • Minimum Focusing Distance = 0,18 m

When you first take the lens, the convex front lens, which has a wide edging that resembles a lens hood, attracts very much attention.

Features of the MIR 20 3.5 / 20 lens:

  • The focus of the lens is very smooth. Due to the fact that the front lens forms a kind of lens hood, the focusing ring remains clamped between the camera body and the “blend”. The focus ring rotates 320 degrees, thus providing a very precise focus for sharpness. When focusing, the front lens does not rotate, and the lens unit with the front lens moves about half a centimeter from the camera.
  • The aperture of the lens is only F / 3.5. But the wide-angle is often used for landscapes, and there is no need for a large aperture.
  • The MIR 20 3.5 / 20 lens shows the depth of field for each aperture value. “Infinity” near the lens begins with 2 meters on the focus scale.
  • There are different versions of MIR 20 3.5 / 20, some do not support the installation of filters at the front of the lens, some use light filters that are installed near the rear group of lenses.
  • The lens is very well assembled. Iron and glass.
  • MIR 20 3.5 / 20 is an ultrawideguide, the focus ring has to be twisted very rarely, and in 90% of cases the lens is focused on infinity.
  • An unusual feature of MIR 20 3.5 / 20 is the minimum focusing distance, which is only 18 centimeters. This is a very good indicator, you can experiment with the prospect, taking off small objects, flowers, etc. The MIR 20 3.5 / 20 lens has one of the shortest focusing distances among the lenses of this class.
  • On the crocheted chambers, ultra-wide-angle lenses, MIR 20 3.5 / 20 including, lose their “over wide-angle” and become the usual “wide-angles”. Of course, on full-frame cameras MIR 20 3.5 / 20 will be of much greater interest.
  • MIR 20 3.5 / 20 – an interesting vintage lens, gives excellent sharpness in the center, loses sharpness around the edges of the frame. One of the few Soviet lenses, which creates a really wide viewing angle on the crozed cameras.
