Lightness joins Tamron 18-200mm F/3.5-6.3 XR Di-II's bundle of remarkable features plus its Tamron Di-II identity (engineered wth image sensors). Equipped with 11.1x zoom, F/22 minimum aperture, ø62 filter diameter, and an internal focusing (IF) system that internally improves minimum focus, this lens is ideal for photography on the go. Equipped with XR (Extra Refractive Index) glass that can bend light rays at steeper angles, low dispersion (LD) glass elements that reduce chromatic aberration, and hybrid aspherical lens elements, the 18-200mm F/3.5-6.3 XR Di-II image quality for portability. It is compatible only with APS-C DSLR Cameras.


Product Features in Detail

Tamron Di-II
These lenses are engineered expressly for digital SLR cameras* with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm. Rendering an ideal image circle for APS-C sensors, Di-II lenses are also include properties to optimize digital imaging performance.

Special Glass for Better Performance and More Compact Lens Designs
XR (Extra Refractive Index) glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimizing optical aberrations. This has allowed Tamron to develop a line of shorter, smaller-diameter, lighter lenses without sacrificing lens speed, and actually upgrading image quality compared to older designs. XR glass is costlier than conventional glass but it yields enhanced optical power distribution, making possible many of the outstanding and innovative lens designs that bear the XR designation. XR glass, with its superior light-bending power, makes it possible to design a short-barrel lens with the same light-gathering ability (aperture value) as a long-barrel lens—even with a smaller lens diameter. By using this principle Tamron has been able to shorten the length of the entire optical system and produce lighter, more compact lenses of the same speed, and also to provide greater zoom ranges in lenses that are much more convenient to carry and hand-hold.

Low Dispersion (LD) Glass for Greater Lens Sharpness
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 low dispersion 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).

Hybrid Aspherical Elements Provide the Ultimate in Image Quality and Compactness
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.

Internal Focusing (IF) System
Internal focusing (IF) 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.

Dedicated for digital SLR cameras
By incorporating an optical design for exclusive use with digital SLR cameras with smaller-size imagers, this high-power zoom lens provides the same focal length, when converted to a 35mm format, equivalent to Tamron's 28-300mm. Therefore, you can meet virtually every photographic opportunity with this single zoom lens without changing lenses. When paired with a wideangle zoom, you can thoroughly enjoy digital SLR photography with a combined equivalent focal length coverage of 27-300mm.

More compact lenses with superior image quality
XR (Extra Refractive Index) glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimising optical aberrations. With its superior light-bending power, XR glass makes it possible to design a short-barrel lens with the same light-gathering ability (aperture value) as a long-barrel lens – even with a smaller lens diameter. By using this principle Tamron has been able to shorten the length of the entire optical system and produce lighter, more compact lenses of the same speed, and also to provide greater zoom ranges in lenses that are much more convenient to carry and hand-hold.

Enhanced peripheral illumination
Peripheral light fall-off is minimised when compared with that of conventional lenses for film cameras so that images are uniformly bright from the centre to the periphery.

Outstanding resolution
Since the lens is designed exclusively for digital SLR photography, it provides high image quality in terms of resolution, contrast and flatness of image field.

Internal surface coating to reduce ghosting and flare
Tamron has adopted various countermeasures against the problem of ghosting and flare caused by aberrations. Internal surface coatings (i.e., multiple-layer coatings on cemented surfaces of plural elements) and new multiple-layer coating technology on ordinary elements, minimise reflections as light enters through the front element and reduce image-degrading effects caused by the imaging sensors themselves.
