Sunagor — manual-focus 80-250mm f/4.5 telephoto zoom with macro, a 1980s budget mail-order lens
The Sunagor 80-250mm f/4.5 is a manual-focus telephoto zoom sold from the 1980s by Sunagor, the Trans-World Trading-owned optical brand better known for binoculars. It was distributed through UK mail order as a budget alternative to first-party telephoto zooms.
It is a push-pull 'one-touch' auto zoom with open-aperture metering coupling and a macro setting near the long end, sold as 'MC 80-250mm f/4.5-4.8'. Focusing is fully manual throughout the range. Filter thread, element count and minimum focus distance are not documented in surviving sources.
Beyond ordinary use, hobbyists in macro and photomacrography circles have reused this lens reversed on extension tubes for high-magnification stacking work, a niche role that keeps clean examples in demand outside conventional telephoto use.
Surviving copies are cheap on UK secondhand and auction sites, most often in Pentax K fittings with Olympus OM and Nikon F also seen. Check the macro coupling and zoom action for smooth travel, and inspect the elements for haze and fungus common in decades-old budget glass.
