The Centon DF-300 is a compact SLR camera body with a Minolta MD SR-bayonet mount. It can be used with most of the lenses which are made for Minolta's manual focus SLRs. It's a copy of Minolta's X-300 which was produced in the same Shanghai, China factory. Centon was the house brand of the UK camera store Jessops, for cameras and accessories including lenses, flash equipment and power winders.[1] Other name variants branded Safari, Seagull and Carena were also sold; the Vivitar V50 seems to be the same camera, as well as Soligor's SR-300 MD.
