EF-Mount Standard Zoom for Full-Frame and APS-C
The Canon EF 24-70mm f/2.8L II USM is a professional standard zoom lens built for Canon EOS DSLRs. Its constant f/2.8 maximum aperture covers the 24 to 70 mm focal range on full-frame 35 mm sensors and on APS-C bodies. The optical design uses 18 elements in 13 groups, including one Super UD element, two UD elements and three aspherical elements. A ring-type ultrasonic motor drives fast, silent autofocus with full-time manual override.
Weather-Sealed Construction for Harsh Environments
Dust- and water-resistant seals protect the barrel during outdoor and event work. Super Spectra and fluorine coatings reduce flare, ghosting and smudges on the front and rear surfaces. The inner-focusing mechanism keeps the lens length constant while focusing, so the balance does not shift during operation. A rounded nine-blade diaphragm produces smooth background rendition across the aperture range from f/2.8 to f/22.
82 mm Filter Thread and Rotating Zoom Ring
An 82 mm front thread accepts standard screw-in filters without vignetting at the wide end. The rotating zoom ring moves smoothly through the 24 to 70 mm range, while the minimum focus distance of 0.38 m (1.25 ft) delivers 0.21x maximum magnification for close-up detail. The lens mounts directly to any Canon EF-mount body, requiring no adapter for full-frame or APS-C formats.

Questions about this item
How do I mount the Canon EF 24-70mm f/2.8L II USM on my Canon EOS body and what step is often missed?
Align the red EF mount index on the lens barrel with the matching mark on the camera flange, twist clockwise until the lock pin clicks, then remove the rear dust cap; people frequently forget the cap and leave the rear element exposed.
What maintenance will the lens need over time?
Clean the front 82 mm filter thread and fluorine-coated front element with a blower and microfibre cloth; the internal USM focus drive and zoom helicoid are sealed and require no user lubrication.
What limit appears first during extended shooting at f/2.8?
The minimum focus distance of 0.38 m (1.25 ft) and 0.21× magnification restrict close-up work long before optical performance degrades.
