SP AF17-35mm F/2.8–4 XR Di LD Aspherical (IF)
Model A05  

Wideangle zoom lens with Di technology – ideal for use with both film and digital SLRs

This zoom lens covers a wide focal length of 17mm, considered ideal for digital SLRs. Their smaller formats and narrower angle of view than film-based SLRs make the wide focal lengths of typical wideangle zooms insufficient for many applications. Accordingly, there is an increasing demand for lenses with a wider angle of view. At the same time, these types of wideangle lenses are well accepted for use with conventional SLRs for their ability to add an interesting twist to photographic expression.

MAJOR FEATURES

Di technology guarantees high-quality digital images
Featuring Di (Digitally Integrated Design), the optical system designed to meet the performance characteristics of digital cameras, the lens lets you take high quality pictures with digital, as well as film-based 35mm format SLRs.

Attractive and useful focal length, 17-35mm
This lens provides a desirable wideangle focal length that is useful and fun for conventional SLR photography and acts as "wide-to-standard" zoom, equivalent to 25.5mm to 52.5mm on a Nikon DX-format SLR.

Consistent MOD of 30cm throughout the zoom range
With its maximum magnification ratio of 1:5.4 at the 35mm setting, this ultra-wideangle zoom enables creatively dramatic close-up shots, with a very near main subject emphasised and exaggerated against a wide background. The impressive MOD of only 30cm throughout the zoom range is the best in this class of lens.

Fast maximum aperture of f/2.8 at wideangle zoom
The maximum aperture of f/2.8 at the 17mm setting offers the advantage of shooting in dimly-lit conditions and helps to prevent the camera-shake that leads to blurred subjects. The fast aperture also allows more opportunity for selective focus, especially at the wideangle position, where depth of field is commonly deeper.

Aberrations corrected through the use of compound aspherical and LD elements
Image distortion, spherical, and other aberrations have been effectively corrected and eliminated through the use of three large compound aspherical elements, enabling high-definition photographs at any focal length. Moreover, colour anomalies such as chromatic aberration - characteristic of many wideangle lenses - have been diminished through the use of an LD element. This special glass compensates for lateral aberration, providing sharp and correctly coloured images even at the corners.

Maximum shading with supplied flower-shaped hood
The large-size flower-shaped hood, provided as standard accessory, is shaped to most efficiently and effectively cut flare from outside the lens' angle of view.

The form and texture of the lens indicate the SP* series' high performance and precision
The high-performance, precision "look" of this lens is fitting for the Tamron SP series. Finishing touches like the graphic display on the lens that features a more visible font, the finish of the lens barrel that utilizes a high quality, delicately wrinkled enamel that is not only durable but offers a comfortable feel, and more all add up to make a lens that handles and functions superbly in the field.

*SP: "Super Performance" - a line of high-performance lenses featuring high design specifications. In designing the SP series, the first and foremost priority is put on superior specifications and outstanding performance free from cost restraints. Therefore, SP lenses featuring impressive and innovative designs are concept models among Tamron lenses.
