This is a high performance super telephoto lens with a focal length of 500mm that utilizes catadioptric system while enabling handheld shooting due to being lightweight and compact.
Reflex lenses have two significant features: one is the ability to almost completely compensate for secondary chromatic aberration which is more likely to occur at longer focal lengths in general dioptric system; the other is a dramatic reduction in the overall lens length due to the light path being looped back.
While making the most of these advantages of catadioptric system, optimal positioning of the optical system based on Canon’s own new optical design technology is used to properly compensate for various aberrations including aberration changes resulting from focusing that tend to occur in reflex lenses, providing quality image reproduction in all shooting ranges from close distances to infinity.
Moreover, in order to prevent reductions in contrast resulting from inner reflection, which is a problem in reflex lenses, the entire lens is given multilayered coating in addition to meticulous consideration being taken, such as electrostatic flocking being performed inside the lens barrel.
Furthermore, it has the feature of filters being able to be replaced with the lens attached to the camera by adopting a filter that is inserted into the light path.
* The reflex lens has the reflecting optical system with mirrors. Therefore the aperture of this lens is f/8
