Photokina — Canon Inc. showed prototypes of two new telephoto lenses, EF500mm F4L IS II USM and EF600mm F4L IS II USM for use with all EOS single-lens reflex cameras.
Both EF500mm f/4L IS II USM and EF600mm f/4L IS II USM were designed to produce high-quality images with high levels of resolution and contrast as well as be lightweight. They will containfluorite lens elements to help minimize chromatic aberration and eliminate color blurring around the edges of the subject.
The two lenses will replace the now 11 year old EF500mm F4L IS USM and EF600mm F4L IS USM which were highly regarded by professional users for use under challenging conditions such as press photography, sports photography and nature photography.
