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.
