Unused, dead stock, manufactured in 1983. This is a Helios 44-2 with a square aperture, known as "square aperture." It's a rare lens that enthusiasts are desperately seeking, as it's hardly available on the market. Occasionally, you might see modified lenses with a square aperture, but these are modified by making the aperture blades square and fixing them in that position, so the aperture value cannot be changed. This lens is a genuine square aperture lens, so you can change the aperture from wide open to f/16. This time, we imported a new, unused, and fully serviced lens, so there are no operational issues. The lens surface is also clean. There are no plans to acquire more in the future, so don't miss out! Disassembled and serviced, no operational issues.
