a high performance ultra wideangle zoom
lens designed exclusively for digital SLR cameras using APS-C
size image sensors.
The lens provides reliable performance in a compact size to
meet the needs of digital SLR camera users pursuing
creativity in wideangle photography. The lens uses a new
optical system specially designed for digital SLR cameras,
in addition to the use of a glass-molded aspherical element
having a large clear aperture, hybrid aspherical elements,
and elements using such special glass materials as high
index/high dispersion glass and low dispersion optical
glass, for outstanding optical performance.
* "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.
