This lens is ideal for sports and wildlife photography
This lens is ideal for sports and wildlife photography. The newly
designed optical system has one fluorite element and two UD-glass
elements to obtain high resolution and high contrast. Also, the minimum
focusing distance was reduced to 5.5 m. Extender EF 2x can be attached
to increase the focal length to 1200mm while retaining AF (with the
EOS-3)
Photo Quote: Photographs are perhaps the most mysterious of all the objects that make up, and thicken, the environment we recognize as modern. Photographs really are experience captured, and the camera is the ideal arm of consciousness in its acquisitive mood.- Susan Sontag
