Description - Tamron 18-200mm F3.8-5.6
XR DI II LD Aspherical (IF) AF lens For Canon
Tamron 18-200mm F3.8-5.6 lens (Model A14) is
a new high power zoom lens designed exclusively for
digital SLR cameras using APS-C size image
sensors. The new Tamron
18 200mm F3.8-5.6 XR DI II LD lens is a high power zoom lens
for exclusive use with digital (APS-C size)SLR cameras that inherits the product
concept of the existing AF28-300mm F/3.5-6.3 XR zoom lens. Even two years after
its introduction, the current AF28-300mm is still a favorite and highly
evaluated by photographers around the world as a representative model of high
power zoom lenses. With the market influx of digital SLR cameras in recent
years, the use of high power zoom lenses has become increasingly popular since
high power zooms provide the convenience of handling many photographic scenes
and the capability of shooting ultra telephoto shots without changing lenses.
The popularity of this focal length led Tamron 18-200 mm
F3.8-5.6 Aspherical (IF) AF lens to initiate the development of new
zoom lenses to further meet the needs of digital SLR photographers. The result
is the successful development of a new zoom lens exclusively for use on digital
SLR cameras. The wide to ultra tele focal range of this lens will allow digital
SLR camera owners to enjoy digital photography with comfort and convenience. By
incorporating an optical design for exclusive use with digital (APS-C) SLR
cameras, Tamron 18-200mm F3.8 5.6 lens provides the
focal length equivalent to Tamron's 28-300mm (when converted to a 35mm format).
Therefore, you can meet almost all photographic opportunities with this single Tamron
18-200mm F 3.8-5.6 Aspherical (IF) AF lens without changing
lenses. When paired with the SP AF11-18mm zoom lens, simultaneously introduced
by Tamron at Photokina, you can enjoy thoroughly digital SLR photography with
the combined focal length coverage of 17-300mm.
* "Di (Digitally Integrated design)-II" is the designation Tamron puts on lenses
designed for exclusive use with digital (APS-C size) SLR cameras, featuring
optical systems optimized to meet the performance characteristics of
digital cameras.
* "Di-II" lenses cannot be used with digital SLR cameras using image sensors
that are larger than that of an APS-C size imager, or with 35mm film SLR
cameras.
