With Tamron SP 28-75mm F/2.8 XR Di, one doesn't have to worry about sacrificing optimum photographic quality to capture special sights and ambience, especially if optical performance is the priority. With its Hybrid Aspherical Elements, combined with its F/32 minimum and F2.8 maximum apertureø67 filter diameterLD (Low Dispersion) glass, Special XR (Extra Refractive Index) glass can bend light rays at steeper angles, and an internal focusing system that provides a better minimum focus, this lens claims the seat for the ultimate in image quality, sharpness, and compactness. It is compatible with APS-C and Full Frame Sensor DSLR Cameras.


Product Features in Detail

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.

Far superior image quality – while reducing lens size and weight
Tamron uses several hybrid aspherical lens elements in its lenses bearing the Aspherical designation. The benefits are two-fold: first, their non-spherical shapes virtually eliminate spherical aberration and image distortion. Second, as one hybrid aspherical lens element can take the place of multiple elements without compromising performance, they allow the lens to be much more compact.

Tamron XR technology creates the world's lightest and most compact fast standard zoom lens
Enabling unprecedented reductions in size, Tamron's XR technology was first used to create the AF28-200mm XR Super Zoom (Model A03) released in 2001, then the world's lightest 28-200mm zoom, and the AF28-300 XR Ultra Zoom (Model A06) released in 2002 as the world's lightest and most compact* 28-300mm zoom lens. Now compactness and light weight are combined with high SP-characteristic performance in this unprecedented "standard zoom" lens.

An innovative combination of optical technologies
The revolutionary use of XR (eXtra Refractive index) glass enables reduction in size while at the same time compensating for aberrations, resulting in the optimisation of overall optical power distribution. Through an optimal arrangement of four hybrid aspherical elements, compositional capabilities have been maintained while achieving a reduction in the dimensions of the overall optical configuration. The use of three LD (Low Dispersion) elements ensures superb image quality.

Structural innovations enable significant downsizing, reduction in zoom torque and torque fluctuation
Thanks to mechanical innovations that enable a very complex structure to be compressed into a compact barrel, the maximum lens diameter has been downsized considerably to a mere 73mm (2.9"). Handling is enhanced with the reduction of zoom torque and improved torque fluctuation. Tamron has also implemented advancements in manufacturing technology, enabling the production of lighter, stronger and higher precision parts.

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.

Sharpens edges by reducing 'colour fringing'
Chromatic aberration occurs when a lens element refracts different wavelengths of a ray of light – its rainbow colours – at very slightly different angles. This results in the 'colour fringing' that reduces the sharpness of an image. LD elements are made from special glass materials with extremely low dispersion indices (i.e. the refraction of a ray of light into rainbow colours is extremely narrow). Thus they effectively compensate for chromatic aberration at the centre of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (toward the edges of the field) that often occurs at short (wideangle) focal lengths.
