A versatile, fast aperture telephoto lens for both digital and film SLR cameras. Two ELD glass elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast.
The new multi-layer lens coating reduces flare and ghosting, a common problem with digital SLR cameras.
The Internal Focus system ensures the overall length of the lens does not change during focusing, ensuring convenient handling and ease of use.
A drop-in 46mm filter holder in the rear part of the lens barrel can be rotated to facilitate the use of filters, including a polarising filter, in situ.
Simply adding an APO teleconverter (optional extra), means that this lens can be used as a 420mm F4 AF ultra-telephoto lens with a 1.4X EX teleconverter, or a 600mm F5.6 AF ultra-telephoto lens with a 2X teleconverter.
