Helios-40-2 85 mm f/1.5 MC Lens for M42 Camera . Modern manufacturing. Brand new. Kit in factory box.

Helios 40-2 lens is a heavy-duty beast that can withstand harsh elements and deliver stunning, artistic results. This means the Helios 40-2 is excellent for portrait photography, isolating the subject from the background to deliver stunning detail. Very sharp lens. It is focusing in full range, including infinity.

The high-aperture lens is intended to shoot portraits, street scenes in low light, fast moving objects that require small exposures etc. Using the multilayer achromatic antireflection coating enables to significantly enhance a transmission factor and practically fully eliminate the adverse scattered light which allows to photograph even if there are bright sources of light in the field of view (the Sun, lamp etc.).
