Manufacturer description

The "МС Апо Телезенитар-К" 4,5/300 lens is designed as an interchangeable lens for "Зенит" type SLR cameras with 24x36 mm format and "К" type bayonet mount.

A compact telephoto lens recommended for shooting distant subjects, photo hunting and sports reporting.

Small dimensions and weight, combined with a reliable "jumping" aperture mechanism and an original design of focusing at the final shooting distance, make it especially attractive to amateur and professional photographers.

The main advantages of this model:

  • excellent image quality and high resolution;
  • good color reproduction of both large and smallest image details due to the almost complete correction of chromatic aberrations through the use of special grades of glass;
  • multi-layer anti-reflection coating that increases light transmission and eliminates the harmful effects of glare in photographs;
  • small dimensions;
  • an original focusing mechanism that provides a slight increase in the length of the lens when shooting at a minimum distance.

Resolving power, lines/mm: in the center of the field: 60; at the edges of the field: 35.

From the editor

The lens was produced by the Krasnogorsk Mechanical Plant (USSR).
