The Canon EF 100mm f/2.8 Macro is an autofocus short-telephoto macro lens for Canon's EF mount, introduced for 35mm SLRs and later DSLRs. Designed for life-size 1:1 reproduction, it suits close-up subjects such as flowers, insects and product work, and doubles as a short portrait optic.

Sales data is thin: a single UK auction hammer result from November 2025 shows a copy selling for £100, which sits as both the recorded low and high in the dataset. With only one wholesale saleroom datapoint to work from, today's typical worth and price for a clean user example cannot be reliably narrowed beyond that figure, and buyers should treat it as indicative rather than a firm market median.
