(Revised Dec 15, 2011) Innovative lens
is lightweight, compact, and features a striking new form factor with two color options to suit the
Sony mirrorless interchangeable-lens camera series design.

| For Sony mirrorless interchangeable-lens camera series |
December 8, 2011, Commack, New York ― Tamron Co., Ltd., a leading manufacturer of optical
equipment, announced the introduction of an exciting new lens, the 18-200mm
F/3.5-6.3 Di III[1] VC
(Model B011). The new high-power all-in-one
zoom lens is designed for the Sony mirrorless interchangeable-lens camera series.
Tamron, the zoom lens pioneer, brings 19 years of high-power zoom lens
development technologies to this new product. The lens will begin shipping in
the U.S. December 15, 2011.
With the 18-200mm Di III VC (Model B011), Tamron
has created a high-power all-in-one zoom lens that is compact and lightweight,
featuring a 62mm filter and weighing only 16.2 oz., while at the same time
delivering superlative image quality. This compact size lets users easily shoot
across an extended range - from wide-angle to full telephoto - with just one
lens. The focal length coverage is
18-200mm. Converted to the coverage of the 35mm format, this is equivalent to a
range of 27mm wide-angle up to 300mm full telephoto[2].
This allows the user to easily take wide-angle shots of expansive landscapes
and powerful telephoto images that enlarge the details of distant subjects—all
with one lens. In addition, by setting the lens at the telephoto end (200mm)
and moving in to the minimum focus distance of 19.6", flower petals,
jewelry and other small objects can be shot as expanded close-ups.
Product Features
n
Compact and lightweight
The high-power 18-200mm all-in-one
lens is a lightweight and compact zoom weighing 16.2 oz. with a 62mm filter, designed
for exclusive use on the E-mount lens system on Sony’s mirrorless
interchangeable-lens cameras.
n
Built-in stabilization enables easy
handheld shooting from 18mm wide angle to 200mm full telephoto
Equipped with Tamron’s acclaimed
VC (Vibration Compensation), and thanks to its light weight and compact size,
this lens allows easy handheld shooting of sharp images with no camera shake
over a wide range of settings, from everyday snapshots to memorable travel
scenes.
n
Stepping motor adopted for the AF drive, a construction
that accommodates contrast-detection AF and shooting video
The AF drive has a stepping
motor that is optimal for the Contrast-detection AF system employed by Sony’s
mirrorless interchangeable-lens cameras. This also gives the drive a quieter
operation, which is ideal for shooting video in which voices are recorded. In
addition, ease of operation is enhanced with the Direct Manual Focus (DMF)
function, which allows the user to make fine manual adjustments after initially
focusing by AF.
n
Striking appearance worthy of the Sony mirrorless
interchangeable-lens camera series design.
The metallic lens barrel
exterior is available in two colors: black and silver.

About the stepping motor
The B011’s autofocus mechanism
uses a stepping motor that is an ideal match for the Contrast-detection AF system
used in Sony’s mirrorless
interchangeable-lens camera series. The stepping motor’s actuator allows finely tuned
control of angular rotation, and since it drives the focusing mechanism
directly without an intermediate reduction gear, it also provides superbly
quiet performance.
About the VC (Vibration Compensation) system
Tamron’s VC mechanism employs
a three-coil system, whereby three driving coils activate the
shake-compensating VC lens group electromagnetically via three steel balls. The
VC lens elements are held in place only by contact with the steel balls,
achieving smooth movement with little friction. This provides a stable
viewfinder image with excellent tracking performance that eliminates the blur
from handheld shots for cleaner, crisper shots.
About the new VC mechanism (moving coil system)
Tamron’s conventional VC
(Vibration Compensation) unit has a moving magnet system with heavy magnets in
the vibration-compensating lens. However,
the new VC mechanism adopts a lightweight moving coil system that reduces the
load on the drive system. This allows the drive to be operated with smaller
coils and magnets, reducing the weight and size for the entire VC unit. In
addition, improvements to software and other elements of the VC mechanism used
in the 18-200mm Di III VC have made the mechanism even quieter.
About Tamron
Tamron is a leading manufacturer of photographic lenses.
Among its many optical and mechanical innovations since the founding of the
company in 1950, Tamron's development of mass-produced hybrid Aspherical
elements paved the way for today’s compact high power all-in-one lenses when,
in 1992, this technology was incorporated into the ground-breaking 28-200mm.
Tamron continues to lead in this category of lenses with the new 18-270mm Di II
VC PZD — the world's smallest and lightest 15X zoom lens featuring Tamron's
proprietary VC (Vibration Compensation) system for blur-free hand-held shooting
of photos in low light and at telephoto settings and PZD (Piezo Drive)
autofocus system for fast and quiet AF operation. Tamron has garnered
international acclaim for its extensive line-up of professional and consumer
lenses.

NOTE: When using Continuous AF (AF-C) Mode
-
Due to an inherent
characteristic of this TAMRON lens, when using the Sports Action mode on Scene
Selection, the continuous operation of the focus search function may cause some
fluctuation in the LCD monitor image. However, there will be no associated
problems on photos taken in this situation.
-
In other Shoot Modes (P, A, S,
M), when the focus mode is set to Continuous AF (AF-C), the same condition may
also arise. There will also be no
associated problems on photos taken in this situation.
- As an alternative to either of the above settings, you
can change the focus mode to Single-shot AF (AF-S) or Direct Manual Focus (DMF)
and continue shooting.

This lens was
developed, manufactured and will be sold based on the specifications for the
E-mount that was disclosed by Sony Corporation under Tamron’s license agreement
with Sony Corporation.
[1]
Di III (Digitally integrated design): A designation Tamron gives to lenses
engineered specifically for mirrorless interchangeable-lens cameras with no
internal mirror box or pentaprism, adopting an optical design that matches the
characteristics of the digital camera. (Note: These lenses cannot be used with
digital SLR cameras with built-in mirror box or conventional 35mm film SLR
cameras).
[2] As the Sony
mirrorless interchangeable-lens camera series
(NEX-3, NEX-C3, NEX-5, NEX-5N as of December 8, 2011) have an image sensor equivalent in size to
APS-C sensors, the angle of view is 27-300mm when converted to 35mm format.
The angle of view of the lens when used for video on the Sony digital HD video
camera recorder NEX-VG10 is 32.4 - 360mm when converted to the 35mm format.
