All that potential, and in the palm of your hand. The world's lightest, smallest*1 that packs a 15x zoom punch.
In addition to being the most compact and lightest lens in the world*1 with 15x magnification, the Tamron 18-270mm high-power zoom lens boasts the PZD (Piezo Drive) internal autofocus drive, Tamron's first standing wave ultrasonic motor system. Agile performance is virtually guaranteed with an unshakeable new*2 VC (Vibration Compensation). All that, and with a Φ62mm filter diameter and weighing in at 450g*3, this lens is the cumulation of uncompromising research and development to make a lightweight, compact, all-in-one super zoom lens.
The trailblazing PZD (Piezo Drive) delivers smooth, quick autofocus. Combined with VC (Vibration Compensation), this is a winning partnership delivering clear, stable shots even in low light or at the telephoto end. The overall lens size is reduced, easing your ability to capture clean, clear images of high resolution.
The result: express yourself without limits. Whether you're toting it to a casual picnic or an off-road mountain biking expedition, we've engineered a high-powered zoom lens that's not only versatile but also light and compact. The new 18-270mm F/3.5-6.3 Di II VC PZD (Model B008).

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 it does it 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 and all in a lens that delivers sharp, clear photos.
In addition, this lens is packed with the best Tamron technologies, which have enabled a significant reduction in body size. The lens construction comprises 13 groups and 16 elements, which is two elements fewer than the previous model, while use of the hybrid aspherical lens with low dispersion glass has helped achieve a compact design and improved optical performance. In addition, the new PZD autofocus drive and the new VC mechanism were developed as downsizing technologies exclusive to Tamron. This has resulted in a compact lens that is 100 grams lighter and 24% smaller in volume compared with the previous model.
Super smooth and accurate, with a first for Tamron
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.
An all new VC (Vibration Compensation) Low light and telephoto was never this.
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 Sony mount does not include the VC image stabilization functionality, as the body of Sony digital SLR cameras includes image stabilization functionality.
Designed exclusively for APS-C sized digital SLR cameras, this all-in-one zoom covers every angle. Its minimum focal distance of 0.49m (19.3 in) through the entire zoom range and macro capability to 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 digital SLR cameras with APS-C size image sensors, the angular coverage range of this lens is impressive. And even though it has built-in VC (Vibration Compensation), 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. 8cm x approx. 5.5cm) as those taken with a 35mm format camera with a lens of maximum zoom ratio of 1:2.5.
The new 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.

MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.
Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.
Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
