Our take on the Canon EF 24-70mm f/2.8L USM Lens

by Tara W.

Zoom lens that's perfect for portraits

Snap stunning everyday photos and artistic people shots with this versatile Canon zoom lens. Its focal range gives you moderate wide-angle to medium telephoto shooting with Canon EOS SLR cameras. A large maximum aperture throughout the focal range means you'll get well-exposed photos, even when shooting in lower light with slower shutter speeds. Shoot group photos indoors without using a flash. And capture clear outdoor shots — whether the subject is your family at the beach or animals at the zoo.

High-quality optical performance

Canon's superior optics ensure you'll get crystal-clear, high-contrast photos. A multi-coating on the lens minimizes ghosting. Your photos will be clear and detailed across the entire field of view — from one edge to the other — thanks to one UD (Ultra-low Dispersion) element and two aspherical elements.

Overview: The Canon EF24-70mm F2.8L USM lens is a high-performance, water-resistant, and ultra-wide angle to standard Canon L-series lens. The lens features an Ultrasonic Motor (USM), with two aspherical elements and one UD element for outstanding image delineation. The lens includes the LP1219 Lens Case and the EW-83F Lens Hood.

Ultrasonic Motor (USM): The EF 24-70mm lens is equipped with a ring-type Ultrasonic Motor (USM) for silent, high-speed auto focusing.

Focusing Ring: Regardless of whether you're in manual or auto focus mode, the focusing ring always works. This means you can auto focus on a subject, but manually change the focus by turning the focusing ring.

Focus Mode Switch: You can switch between Auto Focus and Manual Focus using the two-way switch on the barrel of the lens.

Zoom Ring: The lens has a rotary type zoom ring. The lens barrel indicates the zoom range between 24mm and 70mm, with marks at 28mm, 35mm, and 50mm.

Water/Dust Resistance: The lens mount has a rubber ring for enhanced water- and dust-resistance.

Lens Hood: The lens kit includes the EW-83F lens hood to keep unwanted light out of the lens, and protects the front of the lens. The hood can be reverse-mounted on the lens for storage. When installed, the hood adds approximately 2-1/8 to the overall length and 7/8" to the overall diameter of the lens.

Optional Filters: The EF 24-70mm lens has an 77mm mounting thread on the front of lens for attaching screw-on type filters.

Sharp and beautiful

Written By Pam, Soddy Daisy, TN on Friday, April 15, 2011
Crutchfield Customer Review (What's this?)
I replaced the kit lens on my Canon 7D with this lens, and I am completely in
love. All of my pictures are so sharp. I take a lot of food photos, but also like to
take street scenes. This lens does it all. My food photos are sharp with perfect
DOF and street scenes are just as good. I used to have one prime lens for
food and a standard zoom for street, now this lens stays on my camera
always. The f2.8 allows me to take my food shots indoors in existing light, and
use the soft evening light when I'm outside.
