This is a listing for the Helios-44M-4, famous for its swirly bokeh. It's one of the old lenses that has increased in rarity due to the recent 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 focus ring is larger, so I personally find this one easier to use. It's one of the old lenses that has increased in rarity due to the recent expansion of demand. Front and rear caps are included. The front cap will be either the clip-on type or the slip-on type, as shown in the image. The body has some minor scratches, but I think it's in quite good condition for an old Russian lens. It's difficult to find items 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 particles, but they are minor and do not affect the image quality. The focus ring has also been greased, so it moves smoothly. There may be some thin, fine wiping marks on the lens surface, which are characteristic of Helios lenses, but they are minor and do not affect the image quality. Both the aperture ring and the focus 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's safer to purchase a well-made one. If you have any questions, please ask. I will answer them as much as possible. I am also listing other rare old Soviet lenses, and I plan to increase the number of items in the future, so please take a look. biotar Helios 44-2
