Helios-40 85mm f1.5 Russian lens. Nicknamed the "bokeh monster," this unique lens produces one-of-a-kind images. The HELIOS-40 lens is designed for portrait photography and provides slightly soft (wide aperture) and very beautiful images. The HELIOS-40 lens was produced in small quantities at the KMZ factory (Krasnogorsk Mechanical Plant) and always had better quality than other Soviet lenses for Zenit cameras. It can be used with many digital Micro 4/3 cameras with an adapter. Generally, almost all Soviet lenses are excellent, and this is no exception! Product Condition: Good +++ The glass is clear and has no scratches, but there is a slight amount of dust. When you look closely at the internal glass, you can see something like air bubbles, but this does not affect the shooting. (Please tap and enlarge the photos to confirm) The aperture blades open and close smoothly, and focusing is also smooth, but there are oil stains on the aperture blades. (This does not affect shooting) I think it is in very good condition for a lens manufactured between 1962 and 1963. Please check the product photos carefully. All functions are available. * Focus: 85 mm. * Angle of view: 28 degrees. * Relative aperture: 1:1.5 (clicks to 1:22). The iris aperture consists of 10 blades, and the shape of the aperture hole is very good. This lens is M39, but it comes with an M39-M42 adapter ring, so you can use it with an M42 adapter. Accessories: Everything shown in the photos. This lens was manufactured over 60 years ago. Please consider purchasing only if you understand this.
