The Cosinon 50mm f/1.7 MC Auto is a lens for cameras. Its production site was in Japan.
50 mm is the specified focal length of the lens. Therefore, it can be classified as a normal lens. The lens is equipped with a maximum aperture of f/1.7. f/16 is the smallest available aperture.
The focus of the lens must be set manually before each shot. To have the subject in focus, you must keep a distance of at least 40 cm from the subject.
For photography, you need a camera with an M42 thread. There is a wide variety of cameras from different manufacturers for this thread. Inexpensive adapters also allow use on digital cameras.
A filter with a 49 mm thread, e.g., an IR filter, can be attached in front of the lens.
