One of the most appealing features of a lens is its "speed".
The so-called "fast" lens (e.g., F/2.8) allows approximately twice the amount of light
into the lens compared to a lens with an ordinary maximum aperture (e.g., F/4).
Therefore, a fast lens offers such picture-taking advantages as:
(1) Use of higher shutter speeds
» Sharp images withoul camera shak
(2) A beautifully blurred off
» Out-of-focus foreground LR Ц

A Real Fast Zoom Lens! The Most Compact and Lightest À New Standard of Lenses for Digital Cameras
F/2,8 Constant Maximum Open Aperture in the History of Fast Zoom Lenses pi ("Digitally Integrated Design”) is # designation
throughout the Zoom Range, Yet Compact hanks to the revolutionary downsizing "XR" tech Tamron puts on lenses featuring optical systems
designed to meet the performance characteristics ol
digital SLR cameras”!

ventional AF cameras using silver habdo Bm
nology employed by Tamron in the developmem of
high-power zoom lenses such as the 285-200mm and
28-300, the dramatic compactness that makes this
lens the world's smallest and hghtest® 1s achieved. So
The relative aperture (re. aperture of a lens) is the
focal length divided by the clear aperture (the actual
size of the effective diameter, where hight actually
passes through)®*Y. Therefore, it 1s comparatively casy
vour previous experiences of...” bought a fast lens, -
in terms of size, 10 make an aperture fast at the e | „ое MOD 33cm (13) over

be repeated. Tamron's new fast standard 700m is a lens the Entire Zoom Kange
cult to achieve the same aperture at the telephoto end ь
And 10 make an aperture at the tele-end as fast as that recommended to those photographers who have had MOD (Minimum Object Distance) of 33cm (137), the closes!
of its wide-end, à lens tends to become quite bulky this experience. Its compactness makes it look and fcel focusing distance among lenses in this class, has been
` like an ordinary standard zoom lens (F/3.5-4,5), yet the realized. A maximum macro magnification ratio of
{ (local length) versatility that a fast constant mux umm aperture offers 1-3 9 can be achieved at the 75mm focal length settine

Shorey lens 15 desima, the cloar aperture of he lens must be larger . и
Achieving the same aperture value with a smaller size Flow er-shaped Hood are Standard
Now, Tamron brings you this ultra-compact zoom lens Darro! (rear view) ELL Rid. Even minute aspects are carefully considered by the
that does not change its maximum aperture through
out the range, even at telephoto! Ths allows use of
the same high shutter speed even when the lens 15
zoomed to prevent camera shake and freeze motion
Plus, the beautifully blurred background effects that
are desired from telephoto lenses can be attained *2
We believe a lens that features F/2.85 maximum open
aperture throughout the entire zoom range, even at ils
telephoto end is worthy of “a real fast zoom lens”
designation. The technology that enables us to realize
this compact fast zoom lens ts à technology of which
employment of such features as the zoom lock mech-
anism designed to prevent self-sbding/extension ol
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, 1s standard
Famron is very proud
