Mamiya's long 645 tele — the manual-focus Sekor C 300mm f/5.6 for distant subjects.

The Mamiya Sekor C 300mm f/5.6 is a long telephoto lens for the Mamiya 645 medium-format system. It is among the longer prime options in the C-series line, extending the system well beyond the portrait telephotos. It served photographers needing reach on the 645 format for distant subjects.

This is a manual-focus lens native to the Mamiya 645 bayonet mount, with a focal length of 300mm and a maximum aperture of f/5.6. The aperture is set by a mechanical ring on the barrel. The optical design covers the full 645 image circle, and the f/5.6 speed keeps the front element and overall mass more manageable than a faster long lens would require.

At 300mm on 645 the angle of view corresponds to roughly a 185-190mm lens on 35mm, giving strong reach with the compression telephotos are known for. The f/5.6 aperture is modest but practical for a lens of this length, and it benefits from stable support given its size and weight. It suits distant landscape detail, some wildlife and any subject where working distance is large.

The 300mm f/5.6 is less common than the shorter 645 lenses and appears intermittently on the used market. Check the large front element and internal groups for haze, fungus and separation, confirm the aperture blades are oil-free and close cleanly, and test the focus helicoid for smooth travel over its long range. Inspect the coating for scratches and verify the mount and any tripod collar are sound.
