Description

This large aperture telephoto zoom lens provides the high quality normally associated with a prime lens. It is the only 100-300 lens in with a fast, constant aperture of f/4 throughout its entire zoom range. The use of Tokina's IF (internal focus) system for the forward lens group allows a minimum focus down to two meters. It also gives one of the fastest autofocus speeds in wide diameter zoom lenses.
