For sale is a Helioplan lens modified for M42 mount. It has been adjusted to focus from infinity to close-up. This lens does not vignette on full-frame cameras. The body shows some scratches, but it is in good condition for an old lens. There is no mold or haze inside the lens. There are some scratches on the lens surface, but it has been confirmed that they do not affect the image quality. Due to the lens's construction, dust easily enters, and there may be some minor dust particles present, but these are insignificant and do not affect the image quality. Both the focus ring and the aperture ring function properly. I am also listing other rare, old Soviet lenses, and I plan to increase the number of listings, so please take a look. Modified Lens: Meyer-Optik Gorlitz Helioplan 55mm f4.5 M42 mount
