Canon has posted more information on the new 300mm F2.8L IS II USM and 400mm F2.8L IS II USM super telephoto lenses as well as the new 1.4x TC MKIII and 2x TC MKIII tel-extenders on their Digital Learning website.
It may be hard to believe that it’s been more than a decade since Canon introduced its first generation of image-stabilized super-telephoto lenses, but it’s true. The EF 300mm f/2.8L IS USM, EF 400mm f/2.8L IS USM, EF 500mm f/4L IS USM and EF 600mm f/4L IS USM, along with the Series II EF Extenders, were introduced in 1999. Even now, most photographers would agree that those products have been and continue to be state-of-the-art in terms of quality and performance.
However, there is always room for improvement. During the past 11 years, Canon has listened carefully to feedback from professional photographers, visiting various shooting locations around the world and making firsthand observations of the issues that are encountered by actual users. At the same time, the company has continued to invest significant funds in research and development, resulting in technology advancements that have made higher performance products possible.
Against this backdrop, Canon is proud to introduce its second generation of IS super-telephoto lenses, beginning with the EF 300mm f/2.8L IS II USM and the EF 400mm f/2.8L IS II USM. Along with the new lenses, Canon is introducing the Extenders EF 1.4X III and EF 2X III. All of these products are scheduled for initial shipments by the end of 2010. Canon has also issued an announcement that the EF 500mm f/4L IS II USM and EF 600mm f/4L IS II USM are currently being developed, with delivery planned in 2011.
