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,
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.
