Helios 44-2 lens mounted on a Praktica MTL 5B.
HELIOS-44M-4 fixed lens made in Russia, the brightness of 2.0 focal length 58mm with thread M42. Designed for analog 35mm SLR mount screw as well as for digital SLR after using the adapter bracket.

Helios (Russian: Ге́лиос) was a brand of camera lenses, made in the USSR. They were usually supplied with Zenit cameras and thus usable with other M42 lens mount cameras such as the Pentax Spotmatic. Some later Helios models were built also for the Pentax K mount.

The Helios-44 and Helios-40 are derivatives of the Carl Zeiss Biotar optical formula.

Footnotes[edit]

  1. ^ The 40-2 is not truly a different optical formula, however its filter diameter was increased from 66mm to 67mm, and its tripod collar was made rotatable. This allows for easier mounting on some cameras. Reflective coatings have also been changed.
  2. ^ There have been many variants of the Helios-44 produced since its inception.
