    10 December 2010, Sigma announced the release of a compact, lightweight lens with a 15 x zoom ratio, equipped with a filter 62 mm diameter, VC (Vibration Compensation) image stabilization and before standing wave ultrasonic motor system of the EF lens SLR, the PZD (Piezo drive). 18-270 mm di II VC PZD (model B008) (hereinafter referred to as the 18-270 mm di II VC PZD) of F/3.5-6.3 DSLR lens for Canon and Nikon mount will be released in Japan on December 20, 2010, and a mounting compatible Sony is scheduled for a later date.

    18-270 mm di II VC PZD boasts the highest zoom range of the world to 15 x magnification for a lens with its compact size and light weight, with the added value of image stabilization of Sigma owns VC. 450 g, measure 88 mm in length (from Monte viso to the tip of the lens) and 74.4 mm diameter 62 mm filter, is something compact and simple to carry.

    Autofocus silent, high speed in a compact lens through integration of new technology of autofocus PZD (Piezo drive of Sigma).

    This lens has a minimum distance of focus of 0.49 m over the entire zoom range and a maximum magnification ratio of 1: 3.8.

    Tamron’s new PZD (Piezo Drive) autofocus technology delivers silent, high-speed autofocus in a compact lens

    Ultrasonic motors are divided into two categories depending on the principle that generates the energy to go the drive: traveling wave motors and standing wave motors. Traveling wave motors include the ring type ultrasonic motor used in the recently launched 70-300mm F/4-5.6 VC USD as well as other lenses, but this lens employs a newer technology, the PZD (Piezo Drive), which functions on the standing wave principle.

    A 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 small friction. This provides a stable viewfinder image with brilliant 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, 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 an internal AF motor, the AF28-300mm F/3.5-6.3 XR 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* without an internal AF motor were designated as “N.” As future lens introductions for Nikon will have the internal AF motor as a standard feature, Tamron has chose to simplify the designation and consolidate all Nikon mount lenses as “N,” eliminating the “N II” designation for future models. This classification code change will be effective from the 18-270mm F/3.5-6.3 Di II VC PZD (Model B008).

    The “N” classification lenses with coupler systems are: AF 55-200mm F/4-5.6 Di II (Model A15); AF28-300mm F/3.5-6.3 XR Di (Model A061); SP AF200-500mm F/5.6-6.3 Di (Model A08); and SP AF180mm F/3.5 Di (Model B01).

    *1For SLR high-zoom-ratio lenses with 15x magnification capability. Current as of December 2010. (Source: Tamron).
    *2 PZD (Piezo Drive) is a standing wave ultrasonic motor system developed by Tamron. The motor is quicker and quieter than DC motors when the AF drive is operated, and compared with ring-type ultrasonic motors, it has an actuator that facilitates lens design and reduced size.
    *3 Di II (Digitally Integrated Design): Di II lenses provide an optimized optical design for exclusive use with DSLRs with APS-C size sensors. Di II lenses cannot be used with DSLRs with an image sensor larger than APS-C size, or with 35mm film SLR cameras.
    *4The Sony mount version is not equipped with the VC mechanism as the bodies of Sony’s DSLRs have a built-in image stabilization function. Consequently, the Sony mount version is referred to as 18-270mm F/3.5-6.3 Di II PZD and does not include the VC designation.
    *5Coupler system refers to a system that uses a shaft to harness the AF motor built into the camera body to operate the lens. The “N” classification lenses with coupler systems are: AF 55-200mm F/4-5.6 Di II (Model A15); AF28-300mm F/3.5-6.3 XR Di (Model A061); SP AF200-500mm F/5.6-6.3 Di (Model A08); and SP AF180mm F/3.5 Di (Model B01).
