This listing is for a 1980's Russian made Jupiter-21M, 200mm f/4 lens. On modern DSLR's and mirrorless cameras this lens is fully manual. It mounts with a standard M42 screw mount. Shown in most of the pictures is an M42 to Nikon F mount adapter (not included).

The images taken with this lens are sharp and the f/4 maximum aperture lets in a reasonable amount of light.

The item images show internal dust that cannot be blown out. Also included in the item images are real sample photos taken with this lens hand-held on a Nikon D7100. As you can see, the internal dust is not noticeable in the resulting images.

This lens was purchased by me from a seller in Ukraine earlier this year. I'm upgrading my lens set so this one has to go.
