Yashica's Super Yashinon 200mm f/4.5 — a coated Japanese M42 medium telephoto prime.
The Super Yashinon 200mm f/4.5 is a Japanese telephoto prime made in M42 mount by Yashica under the Yashinon name. The Super prefix marked the coated Yashinon line, and this 200mm was a medium-long reach lens in the Yashica screw-mount range for distant subjects.
This is a manual-focus M42 screw-mount lens with a 200mm focal length and a maximum aperture of f/4.5. Focus and aperture are set by hand on the barrel. It is an all-metal telephoto of moderate size for its reach. Detailed element figures are not asserted here beyond the verified focal length and aperture, following the accuracy standard.
At 200mm the lens gives useful telephoto reach for sports, wildlife, distant landscape detail and tight portraits, with the modest f/4.5 aperture keeping it manageable. Yashinon telephotos render cleanly stopped down, and the lens suits deliberate long-lens work where the reach and compression are wanted.
Used copies are affordable and less common than the standard primes. Inspect the longer barrel for internal haze and fungus, confirm the aperture blades are clean and oil-free, and check the focus helicoid over its travel. Verify the M42 mount before purchase. An M42 adapter allows telephoto use on mirrorless with a support.
