The Sony Alpha DSLR-A100 is a digital single-lens reflex camera introduced in 2006 as Sony's first DSLR following its acquisition of Konica Minolta's camera business. It uses the Minolta A-mount and was positioned as an entry-level DSLR aimed at enthusiasts moving up from compact cameras.

Hammer prices for the A100 at recent UK auction have sat at the budget end of the DSLR market, with two recorded results of £70 and £80 giving a tight £70–£80 range and a median of £75. As of today in 2026, this is what a working body sells for at saleroom level, and condition, shutter count and inclusion of a kit lens are the main factors that move the value.
