Canon 500mm F/4L IS II USM Prime Telephoto Lens

Succeeding the widely-respected EF 500mm F/4L IS USM and EF 600mm F/4L IS USM, the EF 500mm F/4L IS II USM and EF 600mm F/4L IS II USM are being developed for photographers who require high performance, fast aperture and a longer focal length. Redesigned, lightweight bodies will provide added mobility alongside enhanced protection against dust and water, making them ideal for the toughest shooting conditions.

Super Telephoto Lens
High Power telephoto lenses from 400 mm to 800 mm (APS-C 300 mm 500 mm) and
longer are very expensive, even for the slower versions, but they provide
the ultimate in telephoto photography. Deep pockets are needed for most
lenses in this range, particularly the faster versions, as one lens can cost
more than the average person may spend on photography in their life. A
super-telephoto lens can reveal far-off objects barely visible to the human
eye.
A professional-quality 400 mm /2.8 lens is the ultimate dream lens of many
sports and wildlife photographers, which they may save for years to acquire.
A 600 mm /4 lens is even more striking, but the 16-times magnification of
an 800 mm /5.6 lens can also be used for astrophotography with clear, vivid
results.
Professional photographers are the primary consumers of such magnificent
lenses. A majority of the images we see in publications are shot with these
lenses.
