Tamron AF 28-300mm
f/3.5-6.3 XR Di Aspherical (IF) Ultra Wide Angle-
Telephoto Auto Focus Zoom Lens
Tamron's Di lenses featuring
optical systems for use with
both digital and film
cameras have been highly
evaluated by users around
the world since the
introduction of the first Di
lens, SP AF28-75mm F/2.8
(Model A09), in 2003.
Many users strongly
suggested that Tamron make
the existing non-SP high
power and compact 28-300mm
lens they are using with
their film cameras available
in the Di design in order to
realize the same convenience
and quality images with
digital cameras.
Tamron has redesigned the
conventional AF28-300mm zoom
(A06) to feature the Di
design in order to meet the
demand of those
photographers.
Main Features:
High Image Quality by Virtue
of Di (Digitally Integrated)
Design:
· The "Di" design is
achieved by first improving
our BBAR coatings to a new
multi-coating that
encompasses all of the
benefits of the original but
now further reduces the
ghosting and flare caused by
aberrations, and secondly by
further enhancing our
already stringent quality
control system.
The new AF28-300mm Di is
redesigned as a high power
zoom lens now ideal for use
with interchangeable-lens
digital cameras as well as
film cameras.
Changes
1. Improved Coating:
· Newly developed
Multi-coating ideal for
digital imaging to reduce
ghosting and flare caused by
aberrations and to increase
contrast
2. Enhanced Quality Control:
· Ensure mechanical and and
optical meet new standard
3. Exterior design:
· Di logo on zoom rings
Same Convenience and
Compactness:
· The amazing changes in
angles of view of a 10.7X
zoom lens are now available
for your digital SLR camera.
This opens up a completely
new horizon when combined
with the fundamental
attraction of digital SLR
cameras; the possibility of
confirming the quality or
composition of captured
images on the spot and the
capability to allow the
manipulation of images with
a computer.
The new AF28-300mm Di
enables photographers to
enjoy the convenience of the
high power zoom lens with
digital SLR cameras, while
offering the same
compactness as that of the
previous model designed
primarily for film cameras.
Ideal for Use with
Conventional Film Cameras As
Well:
· The new AF28-300mm Di can
be used with both digital
SLR cameras and
conventional35mm AF-SLR film
cameras. It provides an
impressive angle of view
equivalent to that of
approx. 465mm ultra
telephoto when used with a
digital camera and enables
you to enjoy creative
composition of images at the
28mm wide-angle setting when
used with a 35mm film
camera.
