Canon launches revised versions of its 500mm and 600mm telephoto lenses, making them lighter and more durable. Canon claims that the new lenses will offer a gain of up to four stops with their improved image stabilization systems. Both will include two fluorite optical lens elements for improved optical quality over the UD (Ultra-low Dispersion) glass used in the previous generation of lenses.
Both lenses will have a 9-blade diaphragm. Canon's SWC Subwavelength Structure Coating will be applied to four internal groups to combat flare and ghosting. A new Power Focus mode has been added to help videographers operate manual rack focusing by turning a playback ring. The new 500mm and 600mm lenses will have the new IS mode 3 introduced in the 300 and 400 lenses that were launched last year. This will keep image stabilization disabled until the moment the shutter is pressed so that the effect of stabilization is not seen through the viewfinder while tracking a subject.
Additionally, Canon announces it will showcase a new EF 200-400mm F/4L IS USM EXTENDER 1.4x telephoto zoom lens at the CP+ tradeshow taking place in Japan this week. The new lens is designed for use with any EOS DSLR and includes a built-in 1.4x extender.
