Product Overview

The ultimate extended-range, ultra-wide-angle zoom lens! Wider and longer than
others in its class, this compact, lightweight, high-performance lens for
DSLRs with APS-C size sensors provides 35mm equivalent coverage from 16mm
ultra-wide to 37mm semiwide, a remarkable 2.4X zoom ratio. With a maximum
coverage of over 108°, this state-of-the-art classic is the perfect solution
for expanding your visual horizons. Zoom in close at the 1:1 macro view This
ultra wide-angle zoom lens for digital SLR cameras, with the first-ever focal
length range of 10-24mm-the 35mm equivalent of 16mm ultra wide-angle to 37mm
semi-wide-angle-is a perfect tool for creating dramatic landscape, cityscape,a
nd seascape imagery. At the ultra wide-angle setting, you'll be able to
capture vistas beyond what the eye can see. At the semi-wide-angle setting,
you'll capture scenes with angles of view almost as spectacular. SP AF10-24mm
F/3.5-4.5 Di II Features Di II Portrait macro shot Lenses are designed for
exclusive use on digital cameras with smaller-size imagers and inherit all of
the benefits of our Di products. These lenses are not designed for
conventional cameras and digital cameras with image sensors larger than 24mm x
16mm. Super Performance (SP) for Discriminating Shooters Tamron SP (Super
Performance) series is a line of ultra-high-performance lenses designed and
manufactured to the exacting specifications demanded by professionals and
others who require the highest possible image quality. In creating SP lenses
Tamron’s optical designers put their foremost priority on achieving superior
performance parameters—they are all designed to a higher standard with little
regard for cost constraints. As a result, Tamron lenses bearing the SP
designation feature impressive and innovative designs that have established an
enviable reputation for excellence among those knowledgeable photographers
that demand the very best. Internal Focus (IF) Internal focusing (IF) provides
numerous practical benefits to photographers including a non-rotating front
filter ring that facilitates the positioning of polarizing and graduated
filters, and more predictable handling because the lens length does not change
during focusing. Even more important, Tamron's Internal Focusing (IF) system
provides a much closer minimum focusing distance (MFD) throughout its entire
focusing range. In addition, IF improves optical performance by minimizing
illumination loss at the corners of the image field, and helps to suppress
other aberrations that become more troublesome at different focusing
positions. Low Dispersion (LD) Glass for Greater Lens Sharpness Low Dispersion
(LD) Low dispersion (LD) glass elements in a lens help reduce chromatic
aberration; the tendency of light of different colors to come to different
points of focus at the image plane. Chromatic aberration reduces the sharpness
of an image, but glass with an extremely lowdispersion index, has less of a
tendency to separate (defract) a ray of light into a rainbow of colors. This
characteristic allows the lens designer to effectively compensate for
chromatic aberration at the center of the field (on axis), a particular
problem at long focal lengths (the telephoto end of the zoom range), and for
lateral chromatic aberration (towards the edges of the field) that often
occurs at short focal lengths (the wide-angle end of the zoom range.)
Aspherical Elements (ASL) Provide the Ultimate in Image Quality and
Compactness) Tamron uses several hybrid aspherical lens elements in many
lenses bearing the Aspherical designation. These innovative optics allow us to
achieve the ultimate in image quality, and at the same time produce lenses
that offer remarkable zoom ranges in extraordinarily compact packages. By
perfecting theses cutting-edge advances for series production, Tamron has
advanced the state of optical design, and virtually eliminated spherical
aberration and image distortion from the high-power-zoom series.Through the
effective application of Hybrid Aspherical Technology, one lens elemen tcan
take the place of multiple elements without compromising performance. This is
what allows us to produce remarkably compact long-range lenses that deliver a
uniformly high level of image quality at all focal lengths and apertures.
