Anleitung Zusammenfassung
The USM enables quick and quiet autofocusing. This is especially advantageous for sports photography when quick focusing is required and for stage performances when quietness is essential. The "L" designation indicates the use of top-notch lens glass to obtain superior delineation, resolution, and contrast. : Safety precautions and warnings to prevent malfunction. : Things to know a Safety Precautions 1. 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. 2. 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. a Handling Cautions 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.

Align the lens mount index with the red mark on the camera. Then turn the lens clockwise until it locks in place. • After detaching the lens, attach the dust cap to the rear of the lens to prevent the contacts and lens from getting scratched. • 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.

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.

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.
