Canon EF 100-400mm 4.5-5.6 Image Stabilizer USM Lens,CANON AUTHORIZED USA DEALER

The first EF telephoto zoom lens with a high-magnification zoom range of 100 to 400mm. This is the first L type zoom lens with IS (Image Stabilizer) system. The dual-mode IS mechanism corrects camera shake blurring equivalent to two shutter speed steps. The IS Mode-1 works for normal shooting and IS Mode-2 is suitable for panning shots of a moving subject, stabilizing images in viewfinder. The optical system uses one artificial crystal fluorite and one Super UD (Ultra-low Dispersion) glass lens elements(3rd & 7th), which thoroughly correct chromatic aberration. The minimum focusing distance of 1.8m is achieved throughout zooming range. The floating system in rear focusing system is employed for the first time for EF zoom lens to achieve a high definition for the entire focusing range. A ring USM (Ultrasonic Motor) drives high-speed and silent AF and full-time manual focusing. Linear zooming design with zooming friction adjustment ring gives a good operability of this lens. Extenders EF1.4X and EF2X are compatible to this lens with
