Tamron Announces Pricing and Delivery of New SP 70-200mm F/2.8 DI VC USD Telephoto Zoom Lens
The most compact full-size, high-speed
telephoto zoom lens, delivering leading-edge image quality and featuring
Tamron's proprietary VC (Vibration Compensation) and USD (Ultrasonic
Silent Drive) available starting November 30, 2012 in Canon mount.
November 6, 2012, Commack, NY
- Tamron USA, Inc. announced the release date of the new full-size,
high-speed telephoto zoom lens equipped with VC (Vibration Compensation) image stabilization, and USD (Ultrasonic
Silent Drive) that achieves
leading-edge image quality while boasting the most compact design in its
class. The SP 70-200mm F/2.8 Di VC USD will be available in Canon, Nikon and
Sony mounts. The lens will sell for approximately $1499 and will be
available in Canon mount starting November 30, 2012. Nikon and Sony mount to
- One special XLD (Extra Low Dispersion) glass in concert
with four LD (Low Dispersion) elements minimize chromatic aberrations.
This combined with a new optical design that delivers high contrast and
high resolution throughout the zoom range achieves leading-edge image
quality. Tamron's advanced multi-layer coating technology
dramatically improves lens performance by reducing flare and ghosting
for crisper, clearer images.
- The rounded diaphragm affords the photographer spectacular
blur effects, delivering the kind of rich expression only achievable
with a high-speed telephoto zoom lens.
- The most compact full-size, high-speed telephoto zoom lens
with VC (Vibration Compensation) image stabilization and USD (Ultrasonic
Silent Drive) in its class delivers superior mobility, enabling
photographers to capture the previously unattainable.
- Features USD (Ultrasonic Silent Drive) to power a speedy AF
drive together with a continuous manual focus mechanism.
- The VC (Vibration Compensation) image stabilization mechanism
reduces camera shake to deliver sharp images.
- Moisture-resistant construction helps prevent moisture from
penetrating the lens.
Stabilization and Focusing Systems
VC (Vibration Compensation)
is Tamron's proprietary image stabilization system. Tamron's VC is a
three-coil system, whereby three driving coils activate the
shake-compensating VC lens group electromagnetically via three ceramic balls.
The VC lens elements are held in place only by contact with the ceramic
balls, achieving smooth movement with little friction. This provides a stable
viewfinder image with excellent tracking performance. And as the VC lens may
be moved in parallel using only the motorized control, the mechanical
structure has been simplified, enabling the creation of a more compact lens.
VC System (moving coil method)
Tamron's original VC image
stabilization mechanism utilized a moving magnet system whereby a heavy
magnet was positioned near the moving VC lens element. In the new VC unit,
the positions of the magnet and the coil are reversed, and because of this
the VC optical lens element is attached to the coil. The new VC mechanism
employs a moving coil mechanism with a lightweight coil, and the lighter coil
reduces the load on the drive system. Thus, the lighter, more compact new VC
unit contributes to the lens's overall light weight and compact size.
In the ultrasonic motor, a
piezoelectric element arranged in a ring formation generates ultrasonic
vibrations in a metallic ring stator, and the vibration energy is used to
rotate a metallic ring rotor that is attached to the stator. The rotation
energy is in turn transferred from the metallic ring rotor to operate the
Companion to Tamron's Fast Standard Zoom
SP 24-70mm F/2.8 Di VC USD (Model A007) is a high-speed standard zoom lens
that is also equipped with four features: superior image quality, USD
(Ultrasonic Silent Drive), advanced VC (Vibration Compensation), and is
designed for full-size SLR cameras. By combining these two lenses, the focal
length will be extended from wide 24mm to telephoto 200mm. This lens was the
recipient of the 2012-2013 European Sounds and Imaging Association Best
Product Award: Lens.

telephoto zoom lenses for full-size SLR cameras, equipped with VC image
stabilization and USD. Current as of September 2012. (Source: Tamron)
2. VC (Vibration Compensation) is Tamron's
proprietary image stabilization mechanism.
3. USD (Ultrasonic Silent Drive) is
Tamron's proprietary ultrasonic motor drive.
4. The Sony mount does not include VC, as Sony digital
SLR bodies include image stabilization functionality. The Sony lens is
designated as "SP 70-200mm F/2.8 Di USD"
5. The XLD (Extra Low Dispersion) glass is made from
specialized high-grade, which offers greater chromatic aberration correction
properties than LD (Low Dispersion) elements.
6. This rounded diaphragm retains a nearly circular
shape even when taken two stops down from its fully open state.

8. Entire length is the distance between the tip
of the lens and the tip of the protrusion.

Coupler system refers to a system that uses a shaft to harness the AF motor
built into the camera body to operate the lens.
