1. Mounting and Detaching the Lens See your camera’s instructions for details 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. •...
3. Switching the Focusing Distance Range You can set the focusing distance range to 0.48 m/1.6 ft. to infinity or 1.5 m/4.9 ft. to infinity. By setting the suitable focusing distance range, the actual autofocusing time can be shorter. If you autofocus outside the set focusing distance range, the lens may stop focusing at the start of the focusing range;...
5. Infinity Compensation Mark Infinity compensation mark Distance index 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.
7. Picture Taking Normal Photography The lens can be used as a telephoto lens for normal photography. Closeup Photography Close-up photos (minimum focusing distance of 0.48m) up to 1x (life-size) magnification are possible. The minimum focusing distance is the distance from the subject to the film plane. The distance from the front of the lens to the subject (working distance) is about 0.25m.
8. About Exposure Setting the Exposure When taking photographs using TTL metering, no exposure compensation is necessary to meter the light coming through the lens. With TTL metering, AE (autoexposure) is possible at all focusing distances. Just set the desired picture-taking mode, then check the shutter speed and aperture before taking the picture.
9. Macro Flash The Canon Macro Ring Lite MR-14EX or the Macro Twin Lite MT-24EX enables fully automatic macro flash photography up to 1x magnification in E-TTL autoflash mode. Install the Macro Lite Adapter 72C (sold separately) on the filter mounting thread on the front of the lens for macro flash photography.
10. Using the Tripod Mount Adjusting the Revolving Mount You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a particular camera model for switching between vertical and horizontal positions. Detaching First remove the lens from the camera and then remove the tripod mount from the lens as shown below.
(Sold separately) You can attach filters to the filter mounting thread on the front of the lens. • If you need a polarizing filter, use the Canon Circular Polarizing Filter (72mm). • To adjust the polarizing filter, first remove the lens hood.
13. Extenders (Sold separately) With Extender EF1.4X ll or EF2X ll attached, the lens specifications will change as follows: Item Focal length (mm) stops Aperture stops Diagonal Angle of view Vertical Horizontal Maximum magnification (×) • First attach the Extender to the lens, then attach the lens to the camera. Detach it from the camera in the reverse order.
14. Close-up Lenses (Sold separately) Attaching a 500D (72mm) Close-up Lens enables close-up photography. Magnification will be 1.48× – 0.36×. • Close-up Lens 250D cannot be attached because there is no size that fits the lens. • Manual focusing is recommended for accurate focusing.
• The size and weight listed are for the lens only, except as indicated. • Aperture settings are specified on the camera. • All data listed is measured according to Canon standards. • Product specifications and appearance are subject to change without notice.
