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.
