Tamron Developing 70-200mm Tele Zoom

SP 70-200mm F/2.8 Di VC USD for Canon, Nikon and Sony mounts


• The Ultrasonic Motor
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 focus lens.
 
Excellent Companion to Tamron's Fast Standard Zoom
Tamron's 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.

Notice of Classification Code Change for Nikon Mounts
Since the introduction by Tamron of the first Nikon mount lens featuring an internal AF motor, the 28-300mm Di VC (Model A20), all Nikon mount lenses with the internal AF motor had used the classification code "N II." Lenses using a coupler system[10] without an internal AF motor were designated as "N." Because future Nikon lenses will have the internal AF motor as a standard feature, Tamron has decided to simplify the designation and consolidate all Nikon mount lenses as "N," eliminating the "N II" designation for future models. This classification code change was made effective with the 18-270mm Di II VC PZD (Model B008).
 
The "N" classification lenses with coupler systems (no internal AF motor) are: SP 200-500mm Di (Model A08); and SP 180mm F/3.5 Di (Model B01).

[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"

About Tamron
Tamron is a recognized leader in the manufacture of precision optics offering a broad selection of meticulously engineered interchangeable lenses for professional photographers and photo enthusiasts. Founded in 1950, Tamron's passion for innovation brought forth the ground-breaking development of mass-produced hybrid Aspherical elements, giving way to enormously popular compact, wide-range zoom lenses. Dynamic research and development , committed to advanced optical engineering, has produced a stream of award-winning Tamron lenses and defined the All-in-One zoom lens category, exemplified by 2010's 18-270mm Di II VC PZD. Astonishingly compact and lightweight, this 15X zoom features proprietary VC (Vibration Compensation) technology, effectively counteracting image-degrading blur caused by camera shake along with a fast, quiet PZD (Piezo Drive) autofocus mechanism. Tamron lenses deliver a superb fusion of performance and value, enabling today's high-resolution digital SLR cameras to perform at their peak. Tamron's lenses have received numerous prestigious awards from around the world, including 14 EISA (European Imaging & Sound Association) awards, 7 of which were awarded consecutively since 2006.
