Tamron 28-300mm Zoom (APS-C
Digital: 44-465mm 35mm equivalent) |
|
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 foryour 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 wideangle setting when used with a 35mm
film camera.
