MC Helios-77M-4 Rare Russian SLR Lens history

 

MC Helios-77M-4 is Soviet interchangeable lens designed for Zenit, Pentax and Praktica and other compatible SLR photo cameras with frame 24x36mm, M42 screw mount, working distance 45.5 mm and provided by a stop control mechanism. This lens has an automatically “Jumping” stop closing up to a rated degree while photos are taken. Clearing multilayer coating applied onto the lens increases permeability and decreases dissipation of light. This provides favorable contrast and sharpness of the picture. This lens allows to get high quality snapshots in different situations. You can use it on both black and white and color films.
