Tamron 18-270mm f/3.5-6.3 Di II VC PZD Macro Lens (Canon EOS) Lightweight Compact 15x Zoom with Vibration Compensation and Low Light Telephoto Capabilities. 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 thats considerably lighter and noticeably shorter and slimmer 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. Key Features: 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 PZD autofocus drive and the 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. PZD (Piezo Drive) The 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 lenss 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) Tamrons 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. Its 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 VC (Vibration Compensation) mechanism Tamron reversed the positioning of the magnet and connected the lens to the coils. This innovative position thus achieves less load on the drive and combined with lighter coils contributes to a lighter more efficient lens. Minimum focus distance of 0.49m (19.3 in.) throughout the zoom range with macro capability to 1:3.8 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. 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.
