TAMRON AF 18-270mm f/3.5-6.3 Di II VC PZD

B008TSN

All that potential, in the palm of your hand. The light and compact lens packs a 15x zoom punch.

In addition to being a compact and lightweight lens with 15x magnification, the Tamron 18-270mm high-power zoom lens boasts the PZD (Piezo Drive) internal autofocus drive, a standing wave ultrasonic motor system. Agile performance is virtually guaranteed with an unshakeable VC (Vibration Compensation). All that, and with a Φ62mm filter diameter and weighing in at 450g, this lens is the cumulation of uncompromising research and development to make a lightweight, compact, all-in-one super zoom lens. The trailblazing PZD delivers smooth, quick autofocus. Combined with VC, this is a winning partnership delivering clear, stable shots even in low light or at the telephoto end. Easing your ability to capture clean, clear images of high resolution. The result: express yourself without limits. Whether you are toting it to a casual picnic or an off-road mountain biking expedition, we have engineered a high-powered zoom lens that's not only versatile but also light and compact.

A lightweight, compact lens with a high 15x zoom ratio

From wide to telephoto, this 15x high-power zoom lens covers a vast focal range and comes in a light, compact package. At the telephoto end, the 18-270mm is ideal for sports shots or when using distance to capture wildlife in habitat or natural expressions on subjects who normally would be overly conscious of the camera. Whether on vacation or in your own back yard, the wide end gives you the tools to shoot expansive landscapes. Every angle for photographic expression is all in one lens that delivers sharp, clear photos.

The lens construction comprises 13 groups and 16 elements. Use of the hybrid aspherical lens with low dispersion glass has helped achieve a compact design and improved optical performance. Also, Tamron's unique PZD autofocus drive and the VC mechanism is contributing to downsizing.

Super smooth and accurate PZD

The PZD piezoelectric drive is 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.

VC (Vibration Compensation)

Focal Length: 18mm　Exposure: F/4　1/10sec

With VC, the photographer can shoot at a shutter speed up to four stops slower.

VC (Vibration Compensation) is Tamron's proprietary image stabilization system. It employs three driving coils that electromagnetically activate a shake-compensating VC lens group. Since the VC lens elements are held in place only by three ceramic ball bearings, there is smooth movement with little friction. Even when shooting long-range or under low light, the viewfinder image remains stable and tracking response is excellent.

Minimum object distance of 0.49m (19.3 in) with macro capability 1:3.8

The minimum object distance is 0.49m (19.3 in) through the entire zoom range and with a macro capability of 1:3.8 allows you to enjoy serious, high-quality macro photography with unaccustomed convenience. With an optical system designed exclusively for optimum performance on DSLR cameras with APS-C size image sensors, the angular coverage range of this lens is impressive. And even though it has built-in VC, it still delivers a close minimum focus across the entire zoom range. From macro to telephoto this is a lens worthy of your creativity. Light, compact, smooth, and accurate at every angle.

* APS-C size image sensors are smaller than the 35mm film format. This lens can produce full-screen images of almost the same scale (approx. 3.15 in x approx. 2.17 in) as those taken with a 35mm format camera with a lens of maximum zoom ratio of 1:2.5.

Cleaner, crisper images without flare or ghosting

The BBAR (Broad-Band Anti-Reflection) coatings reduce the lens reflection and dispersion that cause ghosting and flare. The coatings enhance light transmission in both the short and long wavelength ranges, ensuring excellent performance in all photographic conditions. Additionally, internal surface coatings are applied to cemented surfaces of all lens elements to deliver sharp, high-contrast images and flawless color reproduction.

Equipped with Fluorine Coating for protection and safe cleaning

The front surface of the lens element is coated with a protective Fluorine Coating that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
