The Panasonic Lumix DMC-G3 is a Micro Four Thirds mirrorless camera introduced in 2011, sold as a compact interchangeable-lens body aimed at enthusiast users stepping up from compacts. It was positioned in Panasonic's mid-range G-series line when new.

Sales data for the DMC-G3 is thin: a single UK auction hammer result from January 2025 recorded £562, which sits at saleroom level and excludes buyer's and seller's commission. With only one data point in 2026, that figure should be read as indicative rather than a reliable median, and what a clean DMC-G3 is worth today will depend heavily on the lens kit included and overall condition.
