The Minolta X-300 S is a 35mm SLR from Minolta's manual-focus X-series, aimed at the entry-level end of the market when introduced in the 1980s. It uses the Minolta SR (MD/MC) bayonet mount and offers aperture-priority and manual exposure modes typical of the line.

Sales data is thin: a single UK auction hammer result from September 2025 sold for £50, which is the only data point available today and sits at the budget end of 1980s Minolta SLR values. With just one record, it is difficult to state a reliable range or median for what an X-300 S is worth, and saleroom prices (wholesale, before commission) will vary with condition, completeness and whether a working lens is included.
