Thank you for purchasing a Canon product. The Canon EF24-70mm f/2.8L USM lens is a high-performance, standard zoom lens for Canon EOS cameras. • "USM" stands for Ultrasonic Motor. C Features 1. Two aspherical elements and a UD element result in outstanding image delineation. 2. Ultrasonic motor (USM) for quick and quiet autofocusing. 3. Manual focusing is available after the subject comes into focus in autofocus mode (ONE SHOT AF). 4. A truly round aperture hole results in a nicer background blur. 5.
a Safety Precautions a Safety Precautions • Do not look at the sun or a bright light source through the lens or camera. Doing so could result in loss of vision. Looking at the sun directly through the lens is especially hazardous. • Whether it is attached to the camera or not, do not leave the lens under the sun without the lens cap attached. This is to prevent the lens from concentrating the sun’s rays, which could cause a fire.

1. Mounting and Detaching the Lens See your camera’s instructions for instructions on mounting and detaching the lens. • After detaching the lens, place the lens with the rear end up to prevent the lens surface and electrical contacts from getting scratched. • If the contacts get soiled, scratched, or have fingerprints on them, corrosion or faulty connections can result. The camera and lens may not operate properly. • If the contacts get soiled or have fingerprints on them, clean them with a soft cloth.
2. Setting the Focus Mode 3. Zooming To shoot in autofocus (AF) mode, set the focus mode switch to AF. To use only manual focusing (MF), set the focus mode switch to MF, and focus by turning the focusing ring. The focusing ring always works, regardless of the focus mode. C Y P O To zoom, turn the zoom ring. Be sure to finish zooming before focusing. Changing the zoom ring after focusing can affect the focus.
4. Infinity Compensation Mark 5. Infrared Index Distance index Infinity compensation mark To compensate for shifting of the infinity focus point that results from changes in temperature. The infinity position at normal temperature is the point at which the vertical line of the L mark is aligned with the distance indicator on the distance scale. C For accurate manual focusing on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.
6. Hood 7. Filters (Sold separately) You can attach filters to the filter mounting thread on the front of the lens. • Only one filter may be attached. • If you need a polarizing filter, use the Canon Circular Polarizing Filter (77mm). • To adjust the polarizing filter, first remove the lens hood. The EW-83F hood can keep unwanted light out of the lens, and also protects the front of the lens from rain, snow, and dust.
