Ce super téléobjectif CANON EF 300 mm f/2.8L USM, est doté d'un nouveau 

système optique conçu pour optimiser encore la qualité d'image. 

 Sa lentille fluorite et ses deux éléments en verre UD éliminent complètement 

le spectre secondaire. 

Cet objectif assure une qualité d'image exceptionnelle tant le plan de la résolution

 que du contraste. 

 Le stabilisateur d'image optique désormais intégré, permet de gagner l'équivalent

 de 2 vitesses d'obturation afin d'optimiser le rendement de l'objectif en conditions 

de fiable lumière ambiante. 

 Son autofocus est le plus rapide du mondegrâce à son moteur USM et à un algorithme 

de pilotage optimisé.

 Super multi-layer lens coating reduces flare and ghosting 

 Compact L-series telephoto lens with an Image Stabilizer 

which compensates for camera shake with the equivalent effect

 of a shutter speed two stops faster 

 Two Image Stabilizer modes are provided: Stabilizer Mode 1 

and the new Stabilizer Mode 2 which steadies the image during 

horizontal or vertical panning 

 Mode 2 detects the panning direction automatically. The closest

 focusing distance is 4.9 feet 1.5 m

Canon EF 400mm f/2.8L IS USM_Super telephoto L-series lens

 with an Image Stabilizer for use in track and field sports 

as well as low-light nature and wildlife photography. 

The fluorite element and two UD-glass elements result 

in high resolution and high contrast. The ring USM and an 

improved AF drive algorithm make the AF speed the fastest

 in the world when used with the Canon 1Dx.
