For sale is a Helios-44-2, famous for its swirly bokeh. It's an M42 mount. This particular lens is categorized as "beautiful condition +" because it has fewer scratches and lens wipe marks compared to the average Helios. It's one of the old lenses that has increased in rarity due to the growing demand in recent years. Front and rear caps are included. The front cap is either a slip-on type or a clip-on type, as shown in the image. There is no mold or haze inside the lens, and it is very clear. This lens has been disassembled and cleaned, and dust has been removed as much as possible. Due to the structure, dust is prone to enter, and there may be slight dust particles, but they are minor and do not affect the image quality. The focus ring has also been greased, so it moves smoothly. Both the aperture ring and the focus ring move normally. I believe this lens is in overall good condition. As an aside, if you don't have an adapter, I recommend purchasing an adapter made by K&F Concept. Inexpensive adapters that can be purchased for under 1000 yen may lack precision, so it's safer to buy a reliable one. If you have any questions, please ask. I will answer them as best I can. I am also selling other rare Soviet-era lenses, and I plan to increase the number of items, so please take a look. biotar Helios 44-2
