NEW Canon EF 70-200mm f2.8 IS II Lens
We recently recieved word about Canon's new 70-200mm f2.8 IS II lens, This newest version offers improvements on an already solid design including a redesigned optical system and a closer minimum focusing distance. It is fully weatherproof. The mount, focus mode switch, and focusing ring are completely dust-proof and drip-proof. The lens is designed and built to withstand the rigors of everyday use by professional photographers.
The Canon 70-200mm f2.8L IS II USM lens features a redesigned optical system with an added fluorite lens element along with five ultralow dispersion (UD) lens elements to reduce chromatic aberrations and to maintain high-contrast images from corner to corner. To add to its flexibility, the lens has a reduced minimum focusing distance of 3.9 feet, a big improvement over the 4.6 feet of its predecessor. The lens has a ring-type ultrasonic motor (USM) AF motor, that along with a new CPU and AF algorithms, make for fast, quiet AF, and match the capbilities of the new 1D mk IV and 7D.
As well as internal improvements, there also are enhanced external differences. The thickness of the external switches has been reduced to guard against accidental switching and for an improved appearance. Also, something rarely seen in an age of autofocus, the manual focus ring is now wider and has been redesigned for improved manual focusing. get excited...
