The Canon EF 70-210mm f/3.5-4.5 USM is an autofocus telephoto zoom for Canon's EF mount, introduced in the early 1990s as a compact alternative to constant-aperture L-series telezooms. Built around a variable maximum aperture of f/3.5 to f/4.5 and an Ultrasonic Motor, it was aimed at general-purpose 35mm SLR users wanting reach for portraits, sports and casual wildlife.

At UK saleroom level the EF 70-210mm f/3.5-4.5 USM is a budget item today, with the only logged hammer result in our sales history reaching just £15 in April 2023. With a single data point the median and range collapse to that same figure, so it is fair to say the lens sells for very little at recent UK auction and is not a piece collectors chase for value. Anyone asking what a Canon EF 70-210mm f/3.5-4.5 USM is worth in 2026 should treat low double-digit hammer prices as the realistic benchmark before commissions.
