Used Canon EF400mm f/2.8L IS USM

Description

Large-aperture telephoto L lens with a camera shake correction function, which is best suited to field sports photography. Developed as a successor to the EF400mm f/2.8L II USM. A fluorite lens and two UD lenses are used in the optical system to assure very high picture quality. This lens has also a protection glass and a rear filter as standard, which are included in the number of lenses.

The camera shake correction has an effect of approx. two stops^* in terms of shutter speed. This lens has “camera shake correction mode 2″ which corrects shaking of the viewfinder image when, for example, shooting a moving object, and a tripod can be used with the camera shake correction function ON.

High-speed autofocusing is achieved by the weight reduction of the group of focusing lenses and improvement of the autofocusing drive algorithm. A new AF stop function, which stops autofocusing temporarily, is adopted. Manual focusing is performed mechanically to save power.
