Canon 70-200mm f/2.8 L IS III USM Zoom - EF Mount

The Canon 70-200mm f/2.8 L IS III USM Zoom - EF Mount delivers outstanding performance, with a constant f/2.8 maximum aperture that enables fast shutter speeds and an 8-blade aperture that yields attractive bokeh (background blur) across the entire zoom range. Canon Air Sphere Coating (ASC) enhances image clarity and counteracts aberrations regardless of focal length or angle of light, with updated Super Spectra Coatings to significantly reduce lens flare and ghosting. Autofocus performance is improved, as more light is transmitted to more areas of the sensor.

Optical Image Stabilization

This zoom features an Optical Image Stabilizer system that provides shake reduction for up to 3.5 shutter speed stops (tested with the EOS-1D X Mark II DSLR camera). This feature provides more reliable handheld performance and clear image detail in low-light conditions, or at lower ISOs.

Fluorine Coating on Front & Rear Elements

A specially designed fluorine coating on both front and rear elements helps to maintain a clean lens, even after multiple lens changes in rugged field conditions. This coating helps prevent dust, water, oil, and other surface residue like fingerprints from adhering to the lens. The user can quickly and easily dislodge hard particles with canned air and wipe away remaining residue without the need for solvents.
