CP+ 2011: Canon has announced updated versions of its 500mm and 600mm f/4L IS USM professional lenses. Similar to the EF 300mm and EF 400mm f/2.8L IS II USM lenses released last August, the EF 500mm F/4L IS II USM and the EF 600mm F/4L IS II USM feature completely new optical designs and water-repellant Fluorine coatings along with lighter weight construction. A new IS mode has been added that activates stabilization only during exposure. The lenses also offer optional long or short foot tripod mounts suitable for monopods or tripods and an improved tripod collar rotation mechanism for smoother rotation from portrait to landscape orientation.
