This is a listing for the Helios-44M, famous for its swirly bokeh. In recent years, it has become one of the old lenses whose rarity has increased due to the expansion of demand. Some people say that the swirly bokeh is weaker compared to the Helios-44-2, but the optical system is exactly the same, so the amount and depiction of the swirly bokeh are the same. Compared to the Helios-44-2, the focusing ring is larger, so I personally think this one is easier to use. In recent years, it has become one of the old lenses whose rarity has increased due to the expansion of demand. Front and rear caps are included. The front cap will be either the clip-on type or the slip-on type shown in the image. The body has some scratches, but I think it is in quite good condition for an old Russian lens. It is difficult to find something in this good condition in Japan. This lens has been disassembled and cleaned, and dust has been removed as much as possible. Due to the structure, dust is likely to enter, and there may be some minor dust mixed in, but it is minor and does not affect the image quality. The focusing ring has also been greased, so it moves smoothly. There may be some thin, fine wiping scratches unique to Helios lenses on the lens surface, but they are minor and do not affect the image quality. Both the aperture ring and the focusing ring move normally. I think this is a lens that is in generally good condition. As an aside, if you don't have an adapter, I recommend purchasing a K&F Concept adapter. Inexpensive adapters that can be purchased for under 1000 yen may lack precision, and it is safer to purchase a well-made one. If you have any questions, please ask. I will answer as much as possible. I am also listing other rare old Soviet lenses, and I plan to increase the number of items in order, so please take a look. biotar Helios 44-2
