The Sony Alpha a3000 is a digital mirrorless camera using the Sony E-mount lens system, presented in a DSLR-style body. It was positioned as an entry-level model aimed at first-time interchangeable-lens buyers.

At UK auction in 2026, hammer prices for the Alpha a3000 sit at the budget end of the digital mirrorless market, with a recorded sale at £75 indicating roughly what a working body is worth today. With only a single auction record to draw on, the value range is narrow and condition, included lens, and working battery will all influence what an example sells for.
