Canon EF 24-70mm F/2.8 L II USM
The Canon EF 24-70mm F/2.8 L II USM is a professional-grade standard zoom lens built for Canon full-frame and APS-C DSLR cameras. It covers a versatile zoom range with a constant f/2.8 maximum aperture.
With advanced Super Spectra coatings, an ultrasonic focus motor, a 9-blade circular aperture, and weather sealing against moisture and dust, this lens checks all the right boxes for working professionals.
Features of Canon EF 24-70mm F/2.8 L II USM Lens
Dimensions
This is a full-sized L-series zoom, and it shows. The lens weighs 805 grams and stretches to nearly 11 cm in length at the 24mm setting. It’s not something you’ll forget is attached to your camera.
Compatibility
You can mount it on a smaller APS-C body for a 38-112mm equivalent field of view, but the balance feels front-heavy on smaller cameras. It really shines on professional full-frame bodies like the Canon 5D Mark III and similar models.
Ease of Use
Yes, it’s expensive. But the build quality backs up every dollar. Canon’s L-series lenses sit at the top of the product lineup, and this one earns its spot.
The lens feels solid in your hands, even though the outer barrel and filter thread are made from high-grade plastic. The focusing ring is well-sized and wrapped in a rubberized grip with a ridged pattern that makes manual adjustments easy.
There’s no aperture ring on this lens, which only matters if you plan to use it with older film bodies. For digital shooters, it’s a non-issue.

One thing to know: this lens doesn’t have optical image stabilization. If IS is a dealbreaker, Canon’s EF 24-70mm F/4 L IS USM is the alternative, though it sacrifices a stop of aperture.
Focus Lock
A Lock Switch on the barrel lets you pin the focal length at 24mm, which prevents the zoom from creeping forward or backward when you’re storing the lens or pointing the camera downward.
The focus mode switch offers AF/MF settings, and you can override autofocus with manual adjustments at any time without switching modes.
A rubber ring on the lens mount helps seal it against moisture and dust. You can take this lens into challenging weather and rough terrain without worrying too much.
Protection
Canon includes a petal-shaped lens hood (EW-88C) and a protective drawstring lens case in the box.
Angle of View
At 24mm, the Canon EF 24-70mm F/2.8 L II USM gives you a 74-degree view angle. Zoom to 70mm and it narrows down to 29 degrees.
Focusing
The focus ring is wide and offers firm stops at both ends of the range, so locking onto infinity is easy. Polarizer users will appreciate that the 82mm filter thread doesn’t rotate during focus.

Autofocus performance is genuinely impressive. Paired with a Canon EOS 5D Mark III, the lens locks onto subjects in roughly 0.15 seconds.
Light Fall-off
At f/2.8, you’ll notice some light drop in the corners. Stopping down helps, and by f/5.6 the vignetting is essentially gone.
Barrel distortion is minimal at 24mm and disappears completely by the time you hit 35mm.
