Feb 11, 2011 – PRESS SUMMARY – Canon U.S.A., Inc., announced two new versions of its popular Image Stabilizer (IS) super-telephoto lenses. The EF 600mm f/4L IS II USM and EF 500mm f/4L IS II USM super-telephoto lenses deliver incredible image quality at all apertures for professional photographers and filmmakers. It has been 11 years since Canon initially introduced its Image Stabilized 500mm and 600mm lenses and in that time the Company has listened to feedback from professionals and worked to implement their most desired enhancements. Replacing the current EF 500mm f/4L and EF 600mm f/4L IS lenses, both the new EF 600mm f/4L IS II USM and new EF 500mm f/4L IS II USM have experienced a drastic weight reduction making them lighter and more durable than their predecessors. Both lenses also achieve a higher level of image quality through the incorporation of two fluorite optical lens elements which help to minimize chromatic aberration and eliminate color blurring around the edges of the subject. Both new lenses offer improved Image Stabilization, providing the equivalent shutter speed of approximately four steps faster in addition to enhanced durability and operability through thoroughly re-designed optical and mechanical components.
