Sunagor — manual-focus 75-300mm f/5.6 telephoto zoom, sold into Canon EF and other 1990s mounts
The Sunagor 75-300mm f/5.6 is a manual-focus telephoto zoom sold from the late 1980s into the 1990s by Sunagor, the Trans-World Trading-owned optical brand better known for binoculars. It was marketed through UK mail order as an affordable long-reach zoom.
It is an MC-coated auto zoom with a macro setting, weighing around 640g per surviving listings, with a constant f/5.6 maximum aperture across the range and fully manual focus. Filter thread, element count and minimum focus distance are not documented in surviving sources.
Unusually for a Sunagor lens of this vintage, it was also produced in Canon EF mount, a manual-focus holdover sold alongside Canon's autofocus EOS system rather than the older FD bayonet. Today owners commonly adapt it to Sony E and other mirrorless bodies.
Surviving copies are cheap on UK secondhand sites, spanning M42, Pentax K, Canon FD, Canon EF and Olympus OM fittings. Check the macro switch and zoom action for smooth travel, and inspect the elements for the haze and fungus common in decades-old budget glass.
