The Canon EOS-1Ds is a professional full-frame digital SLR introduced in 2002, sitting at the top of Canon's EF-mount autofocus system. It was positioned as a studio and commercial workhorse aimed at photographers who previously shot medium format or large-format film.

Sales data for the EOS-1Ds is thin, with a single UK auction hammer result of £149 recorded in late 2021 — a wholesale saleroom level rather than a retail price. On that limited evidence, the body sells for around the £150 mark today, though condition, shutter count and the presence of working batteries can move the value either way.
