Petzvale Modified for HELIOS 44M-4 Soviet lens + Adapter for Sony E Nex Vintage. This is an original vintage lens made in the former Soviet Union (USSR). Helios-44M-4 - further improvement of the Helios-44M lens. Helios 44m-4 is an interesting lens with an amazing picture and fixed focal length 58mm.
The focusing of the lens is smooth. The focus ring rotates 220 degrees. When focusing, the front and rear lenses do not rotate. The diaphragm has 6 blades. The iris control ring rotates smoothly, stopping at fixed values. This lens does not focus like a regular lens; this lens is designed for artistic photography with subsequent digital processing. The lens produces a bokeh effect similar to a petzval with a fully open aperture and maximum defocusing of the background with the obligatory backlight. Example: the distance to the subject (portrait) is 1.5 m, the distance to the background (flowers) is 3.5 m. The background (flowers) is illuminated by lanterns.
As a result, there is a portrait in the center of the frame, and swirling bokeh at the edges of the frame. To enhance sharpness, little digital processing is required.
The lens is designed to work on SLR cameras with a flange length of at least 55mm, and on mirrorless cameras with an extension adapter that increases the flange distance to 55mm. Aperture ratio: Frome 2 is 16. Focus rank: Frome 0.5m 20m - infinity. How to use with modern cameras? Lenses with an M42 mounting thread (M42 X 1/45.5), such as the lens from this review, are very easy to use on almost any modern digital camera (both SLR and mirrorless), for this it is enough to choose the right adapter (adapter).
The cheapest adapters can be found on aliexpress. Adapters (adapters) with a chip provide more convenience during shooting, usually chips are used to confirm focus and / or exposure metering. The serial number in the photo may differ!! The mechanical systems work smoothly, the glass is clean, without dust, chips and fungus. Thank you for visiting our store!
