The world's smallest and lightest standard zoom lens featuring F/2.8 throughout
the range
Now realized thanks to XR technology, Tamron brings you this light and small fast
zoom. Unlike typical fast zooms, it weighs only 510g, with filter size of 67mm
and overall length of 92mm. The optical performance is of course outstanding with
the employment of an optical system using two XR elements, three LD elements,
and four aspherical elements. All of Tamron's zoom lens technology comes together.
F/2.8 Constant Maximum Open Aperture throughout the Zoom Range, Yet
Compact
The relative aperture (i.e., aperture of a lens) is the focal length divided
by the clear aperture (the actual size of the effective diameter where light
actually passes through). Therefore, it is comparatively easy in terms of size,
to make an aperture fast at the wideangle end of a zoom lens, whereas it is
rather difficult to achieve the same aperture at the telephoto end. And to make
an aperture at the tele-end as fast as that of its wide-end, a lens tends to
become quite bulky.
Now, Tamron brings you this ultra-compact zoom lens that does not change its
maximum aperture throughout the zoom range, even at telephoto! This allows use
of the same high shutter speed even when the lens is zoomed to prevent camera
shake and freeze motion. Plus, the beautifully blurred background effects that
are desired from telephoto lenses can be attained. We believe a lens that features
F/2.8 maximum open aperture throughout the entire zoom range, even at its telephoto
end is worthy of "a real fast zoom lens" designation. The technology
that enables us to realize this compact fast zoom lens is a technology of which
Tamron is proud of.
Special Glass Materials such as LD, XR, ASL Are Used in Abundance
Various types of special glass materials such as LD glass, XR glass and Aspherical
lens elements are used in order to achieve the amazingly compact design and
outstanding specifications not found in conventional lenses and to ensure high
image quality.
The Most Compact and Lightweight in the History of Fast Zoom Lenses
Thanks to the revolutionary downsizing "XR" technology employed by
Tamron in the development of high-power zoom lenses such as the 28-200mm and
28-300mm, the dramatic compactness that makes this lens the world's smallest
and lightest is achieved. So your previous expectations of " I bought a
fast lens, but it is too heavy and bulky to carry around" - need not be
repeated. Tamron's new fast standard zoom is a lens recommended to those photographers
who have had this experience. Its compactness makes it look and feel like an
ordinary standard zoom lens (of F/3.5-4.5), yet the versatility that a fast
constant maximum aperture offers will definitely reshape your photographic horizons.
"Di" - New Standard of Lenses for Digital Cameras
Di (Digitally Integrated Design) is a designation Tamron puts on lenses featuring
optical systems designed to meet the performance characteristics of digital
SLR cameras.
MOD 33cm over the Entire Zoom Rangem
MOD (Minimum Object Distance) of 33cm , the closest focusing distance among
lenses in this class, has been realized. A maximum macro magnification ratio
of 1:3.9 can be achieved at the 75mm focal length setting.
Zoom Lock Mechanism and Flower-shaped Hood Are Standard
Even minute aspects are carefully considered by the employment of such features
as the zoom lock mechanism designed to prevent self-sliding/extension of the
lens barrel while carrying the lens/camera around. And the flower-shaped lens
hood, designed to effectively cut unnecessary stray light that causes flare
and ghosting, comes as a standard accessory.
