EF11-24mm f/4L USM C Y P O ENG Instructions
Thank you for purchasing a Canon product. Canon’s EF11-24mm f/4L USM is a highperformance ultra-wide angle zoom lens, for use with EOS cameras. ●● “USM” stands for Ultrasonic Motor. C Features 1. Use of super UD lens elements, UD lens elements, and two types of aspherical lens elements giving superior definition. 2. SWC (Subwavelength Structure Coating) and ASC (Air Sphere Coating) are utilized to significantly reduce occurrences of flare and ghost created by quite large incident angles of light. 3.
Safety Precautions Handling Cautions Safety Precautions ●● If the lens is taken from a cold environment into a warm one, condensation may develop on the lens surface and internal parts. To prevent condensation in this case, first put the lens into an airtight plastic bag before taking it from a cold to warm environment. Then take out the lens after it has warmed gradually. Do the same when taking the lens from a warm environment into a cold one.
Precautions for Shooting ●● If dirt or dust adheres to the surface of the front lens element, it can easily appear in images due to the lens’s short focal length. In order to avoid this, please remove dirt or dust from the surface of the front lens element by using a commercially available air dust blower. ●● Since this lens has a wide angle of view, light from bright light sources, such as the sun, can easily enter the image area. Please do not look at bright light sources using the camera’s viewfinder.

1. Mounting and Detaching the Lens See your camera’s instructions for details on mounting and detaching the lens. Please be careful when laying the lens sideways. The lens may roll and fall, resulting in injury. Y P O ●● After detaching the lens, place the lens with the rear end up to prevent the lens surface and 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.
2. Setting the Focus Mode To shoot in autofocus (AF) mode, set the focus mode switch to AF. To shoot in manual focus (MF) mode, 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 After autofocusing in ONE SHOT AF mode, focus manually by pressing the shutter button halfway and turning the focusing ring. (Full-time manual focus) 3. Zooming To zoom, rotate the zoom ring.
4. I nfinity Compensation Mark 5. Infrared Index Infinity compensation mark Distance index Y P O To compensate for shifting of the infinity focus point that results from changes in temperature, there is a margin at the infinity (∞) position. The infinity position at normal temperature is the point at which the vertical line of the distance scale L mark is aligned with the distance index.
6. Lens Cap 7. Filter (Sold separately) Lock knobs The lens cap can be attached by pinching the lock knobs and vertically aligning the lens cap with the lens hood as shown in the diagram. C The recessed sections of the lens hood that the cap locks on to are located at the front inside edge of the top and bottom petals. Y P O There is a gelatin filter holder at the rear of the lens. Cut the gelatin filter to fit within the white frames. Then insert the gelatin filter into the filter holder.
