Tamron's
fast telephoto SP AF300mm F/2.8 LD (IF) delivers remarkable and
exacting performance demanded by professionals. Two large LD (Low
Dispersion) elements in the front lens group provide high contrast
and crystal-clear image quality from the full open aperture. With
Internal Focusing, you can maintain optimum holding balance since
the lens'
overall length remains constant during focusing. Our Floating
Focusing System improves optical performance especially at close
shooting distances. Nine specially-shaped aperture blades form
a nearly perfect circle to create excellent background blur for
outdoor portraits. The true value of this lens is apparent when
photographing sports action, low light theater performances, and
wildlife. New is a Canon version that provides an easy-to-use
AF/MF focusing ring, rear filter insertion frame that is compatible
with the standard accessory circular polarizing filter and with
the ring rotation capability from outside the lens, and detachable
tripod mounting stand.

Switching between AF and MF is easily accomplished by sliding
the focus ring back and forth. Manually focusing is smooth and
precise with the focusing ring. |
