The Canon EF 100mm f/2.8L Macro IS USM is a professional L-series short telephoto prime lens. While it excels at close-up and macro photography, it is also highly effective for portraits and other mid-range subjects.

Macro Performance

This lens is designed for true macro shooting. It delivers life-size 1:1 magnification with a minimum focusing distance of just 11.8 inches.

To support handheld shooting, Canon included a Hybrid Image Stabilizer. It reduces camera shake by up to two stops at 1:1 magnification, three stops at 1:2, and four stops at lower magnifications. As a result, you can capture sharp images even at slower shutter speeds.

Autofocus and Handling

The EF 100mm f/2.8L Macro IS USM combines smooth handling with reliable autofocus:

• Fast and Precise AF: A ring-type Ultrasonic Motor (USM) with internal focusing ensures quick and quiet autofocus.

• Full-Time Manual Control: You can fine-tune focus at any time without switching modes.

• Focus Limiter Switch: Choose from three ranges—11.8″-1.6′, 1.6′-infinity, or the full range—for faster performance.

Optical Design

Canon built this lens with advanced optics for professional-level clarity:

• Ultra-Low Dispersion (UD) Element: Minimizes chromatic aberrations and color fringing.

• Super Spectra Coating: Reduces flare and ghosting, boosting contrast and color fidelity in strong lighting.

• Nine-Blade Diaphragm: Produces smooth, rounded bokeh for pleasing background blur.

Build Quality

Like all Canon L-series lenses, this macro lens is designed for durability:

• Weather-Sealed: Dust- and moisture-resistant construction ensures reliability in tough environments.

• Fluorine Protection: The front and rear elements resist fingerprints and smudges, making cleaning easier.

• Optional Tripod Collar: A rotating tripod collar can be added to improve balance on a tripod or monopod.

Compatibility

• Full-Frame Cameras: Optimized for Canon EF-mount DSLRs.

• APS-C Models: Provides a 160mm equivalent focal length, ideal for tighter framing and portrait work.
