Tamron to Ship New 28-300mm Di VC PZD All-in-One Lens on late June for $849
Tamron launches an advanced new all-in-one wide-angle to telephoto zoom lens for
full-frame DSLR cameras
28-300mm F/3.5-6.3 Di VC PZD (Model A010)
Innovative All-In-OneTM zoom integrates state-of-the-art optical design, PZD
(Piezo Drive) and Tamron's exclusive VC (Vibration Compensation) system
to achieve superb image quality in a remarkably compact, lightweight package.
une 19, 2014, Commack, NY - Tamron USA, Inc. has announced the
delivery date of the anticipated 28-300mm F/3.5-6.3 Di VC PZD (Model A010),
an advanced new All-In-OneTM zoom lens for full-frame DSLR cameras. The lens
will be available in the U.S. in both Canon and Nikon mount (Sony mount
availability to be announced) on June 26, 2014 at $849.
Since the launch in 1992
of the 28-200mm (Model 71D) high-power zoom lens - which featured a
revolutionary compact, lightweight design - Tamron has been continually
expanding its portfolio of world class optics to benefit consumers. Having
revolutionized the optical design of the previous 28-300mm (Model A20),
Tamron developed a powerful new, high-power zoom lens for full-frame DSLR
cameras that enhances image quality and incorporates the PZD (Piezo Drive)-a standing-wave
ultrasonic motor system optimized for swift, quiet AF-and the acclaimed VC
(Vibration Compensation) mechanism in an amazingly compact configuration.
Featuring a new,
sophisticated external finish, this lens complements the performance and style
of full-frame DSLRs, while delivering the practical advantages of an
All-In-OneTM zoom lens.
- State-of-the-art optical design
technology delivers superior image quality.
The advanced optical construction of this lens includes four elements of
LD (Low Dispersion) glass, three Molded-Glass Aspherical elements, one
Hybrid Aspherical element, one XR (Extra Refractive Index) glass
element, and one element of UXR (Ultra-Extra Refractive Index) glass,
which has greater refractive index than XR. The full use of specialized
glass elements in its design contributes to making this outstanding lens
as compact and lightweight as possible, while minimizing aberrations,
resulting in superior image quality. Particularly impressive is the
thorough compensation of chromatic aberrations at the telephoto end,
yielding images of enhanced clarity and crispness.
on portability - The lens is now even smaller and lighter.
In addition to
state-of-the-art optical design that facilitates downsizing of the lens body,
the mechanical design leads to a smaller overall lens compared to the
existing Tamron 28-300mm (Model A20). The incorporation of a highly
sophisticated multi-stack-cam layout that takes up far less space as well as
the PZD (Piezo Drive) AF, an autofocus drive system with a simpler, more
compact structure, make it possible to reduce the overall dimensions of this
lens. These technologies are the fruit of Tamron's more than 20 years of
research and development in the high-power zoom lens field.
- Advanced anti-reflection
The application of BBAR (Broad-Band Anti-Reflection) coatings for
suppressing reflections on lens element surfaces minimizes unwanted
flare and ghosting to deliver sharp, crisp, high-contrast images.
- Upgraded cosmetic design -
Elegant tungsten silver brand ring.
Tamron has upgraded the cosmetic design and finish of this lens to
create a more sophisticated, high-end look in keeping with the demands
of discerning full-frame DSLR users. Employing a sophisticated linear
pattern rubber grip on the zoom and focus rings and an elegant tungsten
silver brand ring, this newly designed model accentuates its visceral
presence with understated elegance and class.
- PZD (Piezo Drive) delivers
faster, quieter autofocus action.
The PZD (Piezo Drive), a standing-wave ultrasonic motor system, delivers
faster, quieter, more precise action when the autofocus is engaged. The
full-time manual focus system is easy and intuitive, enabling quick and
convenient manual focus at any time.
- Sharper images with VC
Tamron's acclaimed VC (Vibration Compensation) mechanism reduces image
blur caused by camera shake to deliver significantly sharper images even
when shooting handheld.
- Circular diaphragm facilitates
achieving spectacular blur effects
Using a circular diaphragm, this lens achieves spectacular background
blur effects that enable creative use of depth of field
- Moisture-resistant construction
for worry-free outdoor shooting.
Moisture-resistant construction helps prevent moisture from penetrating
Detailed Feature Explanation
PZD (Piezo Drive)
Ultrasonic motors are classified into two types depending on how
the energy used to move the drive is generated: traveling-wave motors and
standing-wave motors. Traveling-wave motors include the ring-type ultrasonic
motor that has been adopted for the 70-300mm F/4-5.6 VC USD (Model A005) and
other lenses. The PZD (Piezo Drive) adopted for the 18-270mm F/3.5-6.3 VC PZD
(Model B008) and the new Model B016 is classified as a standing-wave
ultrasonic motor system. The standing-wave ultrasonic motor system utilizes
ultrasonic-frequency voltage to extend and turn the piezoelectric
(piezoceramic) element, which causes the entire element to vibrate in an
"S" pattern known as a standing-wave motion. The vibration of the
element generates an elliptic motion at the metal tip, which is attached to
the tip of the piezoelectric element in contact with the rotor. Friction of
the metal tip with the rotor caused by this elliptic motion turns the rotor
to focus the lens. Innovations to reduce the number of parts and simplify operation
also contributed to the lens's reduced size and weight.
Tamron's proprietary VC (Vibration Compensation) system uses a
three-coil system. This system employs three coils that move the VC lens
elements electromagnetically via three ceramic ball bearings. The VC lens
 PZD (Piezo Drive) is a standing-wave type ultrasonic
motor system developed by Tamron. It delivers outstanding speed and quiet
operation in the AF mode. It also provides greater flexibility in design
compared with ring-type ultrasonic motors, thus contributing to reduced lens
 VC (Vibration
Compensation) is Tamron's proprietary tri-axial image stabilization
 The Sony mount does not include VC since Sony camera bodies
include built-in image stabilization. The name of the Sony mount model is
"28-300mm Di PZD" without the VC designation.
This circular diaphragm retains a nearly circular shape even
at two stops down from its maximum aperture.
