The world's smallest, most lightweight 28-200mm high magnification zoom lens. With a minimum focal distance over the entire zoom area of 49cm, and a maximum magnification of 1:4 (at 200mm), this remarkable lens achieves high magnification zoom performance with the compact size of a standard zoom lens. Through XR (Extra Refractive Index) glass and efficient use of aspherical lenses, Tamron has achieved a 25% reduction in size and a 27% reduction in weight over the previous model (Model 371D), along with a decrease in filter diameter by two-steps ø72mm- ø62mm) without compromising the superior image quality characteristic of Tamron 28-200 lenses.

A standard zoom lens from a wide 28mm to a medium telephoto range of 80mm. The use of aspherical elements in the front group reduces the number of elements required, and the use of strong engineering plastic in the barrel makes the body a light 237g. Consequently, it is easy to carry.

Introducing in the third in our series of high power zoom lenses, following on the successes of the 28-200mm and the 28-300mm mega-zoom lenses. The new zoom lens from Tamron covers everything from the 24mm real wideangle that professionals and serious amateurs demand to 135mm telephoto suitable for portraits-all in one compact package. The first SP lens among Tamron's high power zoom lenses, the lens represents a new concept in high power zoom lenses, achieving outstanding performance characteristics worthy of the name SP (Super Performance).

The AF18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro is the ultimate high power zoom boasting the world's greatest zoom ratio of 13.9X, a milestone that Tamron, the pioneer of high power zoom lenses, has achieved by commanding its technologies to further expand the capabilities of high power zoom lenses.To prevent the lens from becoming bulky, the design concept of the AF18-200mm F/3.5-6.3 XI Di-II LD Aspherical (IF) Macro (Model A14), a popular lens among the world's digital SLR users since it is the ideal high power zoom lens, was the basis for this new lens that features an expanded focal length to 250mm at its tele-end. With the new AF18-250mm zoom lens that provides enhanced image quality, Tamron has achieved an astounding 13.9X zoom power, the world's greatest in the class of zoom lenses; yet the increase in size is confined to a mere 0.2mm more in its maximum diameter and just 0.6mm in overall length, in a lens that offers a 388mm ultra telephoto focal length (diagonal angle of view of 6? 23') when converted to the 35mm film format.

With Extra-low Dispersion (ED) glass lens element and two aspherical lens elements, the lens offers more true-to-life image reproduction. The image circle in DA-series lenses is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in PENTAX digital SLRs to optimize camera performance. The new design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications.

Maintaining the high performance of the previous model, Tamron's new 28-300mm zoom lens now features our "Di" design, making it the ideal lens for use with both digital and film cameras. The "Di" design is achieved by applying a new optical design to its coated surfaces, and by further enhancing our already stringent quality control system. Whether you shoot film or digital, the lens provides high image quality for both platforms. When used with APS-C size digital SLR cameras, the lens provides an angle of view equivalent to approximately 44-465mm, covering the standard to ultra telephoto range with no sacrifice of quality or aperture range.
