To mark the 35th anniversary of the Canon EOS line, Canon has announced two RF mount super telephoto lenses: the RF800mm F5.6 L IS USM and the RF1200mm F8 L IS USM. Although the names of these lenses resemble their EF mount counterparts, they differ in optical resolution and weigh slightly less.
In the description of new products, the manufacturer notes that the RF1200mm F8 L IS USM model has the longest focal length among RF mount lenses. Common features of the new lenses include Super Spectra Coating (SSC) and Air Sphere Coating (ASC) to help minimize the risk of flare and other artifacts. Both lenses are compatible with RF1.4x and RF2x teleconverters. It is possible to install filters with a diameter of 52 mm into the lens, for which there is a special slot.
The lenses provide for memorizing two focus positions with the ability to quickly switch between them. The lenses are equipped with an image stabilization function. Three stabilization modes are available, and its effectiveness is declared equal to four exposure levels (according to the CIPA rating).
