• If the contacts are dirty, scratched, or soiled with fingerprints, etc., corrosion or a faulty connection or operation may result. • If the lens is dirty, it may not autofocus properly. 1. Attaching and Detaching the Lens 1 2 3Remove the lens cap by pressing the clasps. Detaching the lens Hold down the lens release button on the camera and turn the lens counterclockwise until it detaches. 1.5m~. AF 3.5m~. M CANO ENG-4 4. Switching the Focusing Distance Range To set the AF mode, set the focus mode switch to AF. To disable the autofocus mode and focus manually, set the focus mode switch to MF and turn the focusing ring. This lens enables manual focusing even in the autofocus mode. With the camera set to the One-Shot AF mode, manual focusing is possible after the lens autofocuses (and stops) while the shutter button is pressed halfway. 2. Setting the Focus Mode 3. Manual touch-up focusing The focusing distance range can be selected with the focusing limiter switch. • EF 135 mm f/2L USM: 0.9 m - infinity or 1.6 m - infinity • EF 200 mm f/2.8L II USM: 1.5 m - infinity or 3.5 m - infinity • EF 300 mm f/4L USM: 2.5 m - infinity or 6 m - infinity • EF 400 mm f/5.6L USM: 3.5 m - infinity or 8.5 m - infinity AF MF 32 32 5 15 2 7 10 3 AF M 10 30 m ft ENG-5 The following applies to the EF 135 mm f/2L USM, EF 200 mm f/2.8L II USM, and EF 400 mm f/5.6L USM lense: • Before switching the focusing range, turn the focusing ring to select a focusing distance somewhere within the desired range. • If you do not set the lens to a focusing distance that is within the selected focusing range, autofocusing may stop when it reaches the range boundary. This is not a fault. If it happens, press the shutter button halfway down again. The following applies to the EF 200 mm f/2.8L II USM, EF 300 mm f/4L USM, and EF 400 mm f/5.6L USM lenses: • If the tripod mount covers the focusing limiter switch, it may be difficult to operate the switch. In such a case, loosen the tripod mount's lock nut and turn the camera so that the switch is clear. The depth of field is the zone of acceptable focus in front of and behind the point of optimum focus. EOS cameras equipped with the depth-of-field preview feature allow you to see this zone of sharp focus in the viewfinder. The depth-of-field scale is an approximate guide. 5.

To ensure accurate focus, look through the viewfinder and check the focus. infrared mark to compensate for the focusing difference. Also use an infrared filter on the lens. ENG-7 • When compensating for the focusing difference, set the focus mode switch to MF and use the focusing ring. • The position of the infrared mark is based on a wavelength of 800 nm. The proper position of the infrared mark may differ slightly depending on the infrared film used. Taking several shots and shifting the distance setting to a slightly different position each time is recommended. • Also read the instructions that came with the infrared film. • Infrared film cannot be used with certain EOS camera models. Read the camera's instructions. The EF 300mm f/4L USM lens and EF 400mm f/5.6L USM lens come with a tripod mount. When the camera is attached with either lens and it is to be mounted on a tripod, use the lens' tripod mount instead of the camera body's tripod socket. If using the EF 200mm f/2.8L II USM lens with an extender or extension tube, use a ring-type tripod mount A (B) (sold separately) to mount it on a tripod. Using the lens' tripod mount gives better balance and stability on a tripod. By loosening the tripod mount's lock nut, the camera can be revolved for vertical or horizontal picture conposition. Be sure to tighten the tripod mount before removing the camera when using a tripod. 9.
