Are you looking For Tamron AF 18-270mm f/3.5-6.3 Di II VC LD Aspherical IF Macro Zoom Lens with Built in Motor for Nikon DSLR Cameras... Product Description Style: Nikon From the Manufacturer With the advent of the latest 15x zoom lens from Tamron, the pioneer of high power zoom lenses, the high power zoom lens has steadily evolved from a 7.1x zoom to the worlds largest zoom ratio of 15x by combining advanced high power zoom design technologies accumulated by Tamron since 1992. The lens covers an angle of view equivalent to that of a 28mm wide-angle to a 419mm ultra telephoto with just one lens, letting the user capture once-in-the-lifetime images of panoramic landscape images or close-up pictures of children smiling, without having to get too close to the subject and without having to change lenses. World’s first 15X all-in-one zoom with built-in vibration compensation Tamron 18-270mm Lens Features Di II Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm. 15x Zoom Ratio This lens covers an extremely broad range of focal lengths, from an extra-wide 18mm length to a telephoto 270mm length (the 35mm equivalent of 28mm to 419mm). The resulting 15x zoom ratio is the worlds largest, representing a wide cross section of Tamron high-power zoom design technologies. Plus, the vibration compensation works throughout the entire zoom range, giving you the freedom to create a wide variety of images. The lens lets users capture once-in-a-lifetime panoramic landscape images or close-up pictures of children smiling, all without getting too close to the subject or changing lenses. Other details include a macro magnification range of 1:3.5, a minimum focusing distance of 19.3 inches, and a 72mm filter diameter. The lens, which measures 3.1 inches in diameter and 3.9 inches long, carries a six-year warranty. 18mm zoom - 270mm zoom Vibration Compensation (VC) Shake can ruin your photos, particularly when taking telephoto shots or shooting in low light conditions.Simply flip the VC switch on and youll notice the difference immediately. VC delivers blur free - handheld images for incredible results VC mechanism employs a three-coil system Lens element compensates for vibration using 3-steel balls (making movement quiet & smooth) Exceptional images at slower shutter speeds – reduces the need for a tripod Bring out contrast to motion & stillness Eliminate the need to shoot with a Flash VC Off - VC On Low Dispersion (LD) Glass for Greater Lens Sharpness Add sharpness to your image with Low Dispersion (LD) glass lenses Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.) Internal Focusing (IF) System Internal focusing provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron’s Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions. Zoom Lock (ZL) Another original Tamron mechanical engineering concept is the Zoom Lock (ZL), a simple convenience feature that prevents undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap. Anomalous Dispersion (AD) for Better Color Correction Anomalous Dispersion Anomalous dispersion (AD) glass is a special type of optical glass that is used to achieve more precise control of chromatic aberrations, thereby enhancing overall imaging performance. Glass of this type provides an abnormally large partial dispersion ratio (amount of diffraction) for light of specific wavelength ranges (colors) within the visible spectrum. By combining AD glass having these special characteristics with elements made of normal glass having different dispersion characteristics, it is possible to control the dispersion factors of a specific wavelength. This enhanced level of control results in much lower levels of on-axis (central) chromatic aberration for telephoto lenses (or zooms used at tele-photo settings) and a significant reduction of lateral (peripheral) chromatic aber-ration for wide-angle lenses (or zooms used at wide-angle settings.) Aspherical Lens Elements (ASL) Tamron uses several hybrid Aspherical lens elements in many lenses bearing the Aspherical designation. These innovative optics allow us to achieve the ultimate in image quality, and at the same time produce lenses that offer remarkable zoom ranges in extraordinarily compact packages. By perfecting theses cutting-edge advances for series production, Tamron has advanced the state of optical design, and virtually eliminated spherical aberration and image distortion from the high-power-zoom series.Through the effective application of Hybrid Aspherical Technology, one lens element can take the place of multiple elements without compromising performance. This is what allows us to produce remarkably compact long-range lenses that deliver a uniformly high level of image quality at all focal lengths and apertures.
