Tamron 18-270mm Di II VC PZD Lens
High-power zoom weighs just 15.9 ouncesA standing wave ultrasonic motor utilizes high-frequency voltage to extend and turn the Piezoelectric (Piezoceramic) element, thus moving the entire element in a standing wave movement. The metal tip is the contact point of the element to the rotor, and moves in an elliptic motion from the swiveling motion of the moving element, and the friction from this motion turns the rotor. Standing wave ultrasonic motors have the distinct advantage of being smaller than their traveling wave counterparts, and therefore allow a more compact SLR lens size.
• VC (Vibration Compensation)
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.
• New VC Mechanism (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.
Notice of Classification Code Change for Nikon Mounts
Since the introduction by Tamron of the first Nikon mount lens featuring a Built-in AF motor (AF28-300mm F/3.5-6.3 XR Di VC Model A20) all Tamron Nikon mount lenses with the Built-in AF motor had a model number designation of “NII.” Lenses using a coupler system without a Built-in AF motor are currently designated as “N.” As future Tamron lens introductions for Nikon mount will have the Built-in AF motor as a standard feature, Tamron has decided to simplify the designation and consolidate all Nikon mount lenses as “N,” eliminating the “NII” designation for future models. This model designation change will be effective with the 18-270mm F/3.5-6.3 Di II VC PZD (Model B008) introduction.
