For sale is a very rare zebra-pattern Helios 92 92mm f2 lens. This is a lens without an aperture. It has an M42 mount. Originally, this was an old lens used as a projection lens or cine lens without a focus ring. This lens has a focus ring (helical focusing mechanism) attached and has been customized for use with an M42 mount. Front and rear caps are included. This lens has very strong swirly bokeh and high descriptive power, characterized by its melting bokeh. There are not many scratches, and I think it is in good condition for an old Russian lens. There is no mold or fogging inside the lens. It is in a clear state. There may be slight wiping marks, but they are minor and do not affect the image quality. This lens has been disassembled and cleaned, and dust has been removed as much as possible, but due to the structure, dust is likely to enter, and there may be some minor dust particles. This is also minor and does not affect the image quality. I think this lens is in generally good condition. As an aside, if you do not 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 reliable one. If you have any questions, please ask. I will answer them as much as possible. I am also selling other rare old Soviet lenses, and I plan to increase the number of items in the future, so please take a look.
