The Minolta SRT-303 is a 35mm single-lens reflex film camera from Minolta's SRT series, a range of mechanical SLRs introduced in the late 1960s and 1970s. It was positioned as an enthusiast-level body with through-the-lens metering and manual exposure control.

At recent UK auction, hammer prices for the SRT-303 have ranged from around £56 to £150, with limited sales data pointing to a rough midpoint near £100 in today's saleroom market. These are wholesale auction results, so what a clean example sells for privately or through a dealer will typically be higher, and condition of the meter, seals and cosmetics has a clear effect on value.
