Product Overview

From the Manufacturer Unleash the picture power of your digital SLR with this
remarkable new compact, lightweight all-in-one zoom lens. Covering an
impressive 10.7X, wide-to-longtelephotozoom range on both full-frame and APS-C
format digital SLRs it gets down to an incredible 0.49m (19.3") at 300mm in
Macro mode for dramatic framefilling close-ups. Zoom in for a macro shot And
to optimize its outstanding real-world image quality we’ve built in our new
high-tech, state-of-the-art VC (Vibration Compensation) system. The cutting
edge 18-element and 13-group design of the 28-300mm VC lens incorporates XR
(extra refractive-index ), LD ( low dispersion) and AD (anomalous dispersion )
glass as well as hybrid and GM (glass molded) aspherical elements to deliver
exquisite sharpness and color correction over its extended range. The esteemed
Di ( Digitally Integrated ) designation is your assurance of optimum digital
and analog imaging performance. Capturing razor sharp handheld images just got
AF28-300mm F/3.5-6.3 XR Di VC Features Di II 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.
Vibration Compensation (VC) Camera shake can ruin your photos, particularly at
telephoto or in low light. Tamron's state-of-the-art Vibration Compensation
mechanism incorporated into the award-winning 28-300mm zoom gives you blur-
free hand-held images for incredible results! Finally, the technology you need
in the lens you want. VC delivers blur free - handheld images for incredible
results VC mechanism employs a three-coil system Lens element compensates for
vibration using 3-steel balls (making movement quiet & smooth) Exceptional
images at slower shutter speeds – reduces the need for a tripod Bring out
contrast to motion & stillness Eliminate the need to shoot with a Flash VC Off
- VC On 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.) Low
Dispersion (LD) Glass for Greater Lens Sharpness Extra Refractive Index Glass
(XR) Extra Refractive Index (XR) glass can bend light rays at steeper angles,
thereby decreasing the physical length of the lens while enhancing imaging
performance by minimizing optical aberrations. This has allowed Tamron to
develop a line of shorter, smaller-diameter, lighter lenses without
sacrificing lens speed, and actually upgrading image quality compared to older
designs. XR glass is costlier than conventional glass but it yields enhanced
optical power distribution, making possible many of the outstanding and
innovative lens designs that bear the XR designation. XR glass, with its
superior light-bending power, makes it possible to design a short-barrel lens
with the same light-gathering ability (aperture value) as a long-barrel
lens—even with a smaller lens diameter. By using this principle Tamron has
been able to shorten the length of the entire optical system and produce
lighter, more compact lenses of the same speed, and also to provide greater
zoom ranges in lenses that are much more convenient to carry by hand. Special
glass for better performance and more compact lens designs 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. Achieve the ultimate in
image quality with Asperical (ASL) lenses 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.
