Rent NowThe Canon EF 100mm f/2.8L Macro IS USM is a versatile L-series short telephoto prime lens designed primarily for close-up shooting, while also well suited to portraiture and other mid-range subjects. It’s aimed at macro, product, and nature photographers who want true life-size reproduction paired with the optical performance and build quality of Canon’s professional L-series lineup.
Optically, the lens offers a 100mm focal length with a maximum aperture of f/2.8, delivering a 23.4-degree diagonal angle of view. The 15-element, 12-group optical design includes one Ultra-low Dispersion element, and Canon’s Super Spectra coating helps suppress flare and ghosting for improved contrast. A 9-blade diaphragm contributes to smooth, natural-looking background rendering, valued by portrait photographers using this lens outside of macro distances.
As a true macro lens, it achieves a genuine 1:1 (life-size) maximum magnification at its closest focusing distance of 11.8 in. (0.3m), extendable to 1.17-0.12x with Canon’s EF12 II extension tube or 1.37-0.27x with the EF25 II. Autofocus is handled by a ring-type Ultrasonic Motor (USM) paired with an internal focusing design, delivering fast, precise, and quiet performance along with full-time manual focus override. The focus ring rotates approximately 150-160 degrees between infinity and closest focus, with gearing optimized for precise macro work, and a focus distance limiter switch helps speed up autofocus by splitting the macro working range from normal shooting distances.
A standout feature is the lens’s Hybrid Image Stabilizer, engineered to compensate for both angular and shift camera movement, a design specifically suited to macro work where shift-type shake becomes more pronounced at close distances. It’s rated for up to 4 stops of correction at conventional shooting distances, narrowing to 3 stops at 0.5x magnification and 2 stops at full 1:1 reproduction.
As an L-series lens, the EF 100mm f/2.8L Macro IS USM features weather-sealed construction suited to working in inclement conditions, along with three control switches on the barrel: an AF/MF switch, an image stabilizer on/off switch, and the focus limiter switch. The lens accepts a 67mm filter thread, measures approximately 77.7 x 123mm, and weighs approximately 625g.
As a full-frame-compatible lens, the EF 100mm f/2.8L Macro IS USM produces its full field of view on full-frame Canon bodies and an effective 160mm equivalent focal length on APS-C bodies.
