The World’s Lightest, Smallest 15x Zoom*, with Tamron’s First PZD (Piezo Drive)
The acclaimed Tamron 18-270mm VC ultra zoom for APS-C format DSLRs has reached an astonishing new level of compactness, performance, and speed with the addition of PZD (Piezo Drive), an innovative ultrasonic autofocus motor based on an advanced piezoelectric design. The result is a lens that’s considerably lighter, and noticeably shorter and slimmer (filter diameter: 62mm) than any previous lens in its class, and provides faster, quieter auto-focusing.
Signature features that have made this amazingly versatile lens the world standard in its class have been retained. They include a 28-419mm equivalent (15X) zoom range, an improved, lightweight, compact Vibration Compensation (VC) system, macro focusing to 0.49m (19.3 inches) throughout, and, of course, superlative imaging performance.
The new PZD (Piezo Drive) piezoelectric drive marks another Tamron first in its autofocus SLR lenses, an internal standing wave ultrasonic motor system. Innovations to reduce parts and simplify operation also contributed to the lens’s reduced size and weight. Lighter and smaller than other autofocus drives, the piezoelectric drive uses a standing wave, instead of the traditional traveling wave, to turn and extend the piezoelectric element. Thus the entire element moves in a standing wave pattern, moving the metal tip (the contact surface) in an elliptic motion. The friction of this movement moves the rotor for a smooth, precise autofocus.
Tamron’s celebrated VC (Vibration Compensation) just got even better. It still offers great handheld and telephoto shots. It still delivers the renowned VC (Vibration Compensation) stable viewfinder image, and excellent traceability. It’s still based on a moving three-coil mechanism that activates the lens group electromagnetically through three steel balls. But technology must evolve. Previously, the heavy magnet was positioned near the lens element and worked very well in this placement. In the new VC (Vibration Compensation) mechanism, we’ve reversed the positioning of the magnet and connected the lens to the coils. This innovative new position thus achieves less load on the drive and combined with lighter coils, contributes to a lighter, more efficient lens.
* VC is an abbreviation for Vibration Compensation, and is also available in the18-270mm (B003), 28-300mm (A20), 17-50mm (B005) and the 70-300mm (A005) models.
The Tamron AF18-270mm f/3.5-6.3 Di II VC PZD AF Lens for Nikon is a 15x high power zoom lens designed exclusively for digital SLR cameras using the more compact (APS-C) digital size image sensors. The focal length of this lens is equivalent to approx. 28-419mm in 35mm format. Designed as an "all-in-one" lens, it will meet almost all photographic opportunities without changing lenses.
