Setting high-performance DSLRs free with SP engineering, strengthened by F/2.8 maximum aperture advantages.
17mm (27mm full frame)
28mm (43mm full frame)
50mm (77mm full frame)
The Tamron SP designation is reserved for lenses developed with special emphasis on extraordinary photographic performance. Engineers are free to innovate in an uncommon atmosphere where optical performance comes before price, resulting in lenses that satisfy the demands of discerning photographers.
One of two Tamron 17-50mm F/2.8 offerings, the image integrity and compositional options afforded by the SP 17-50mm F/2.8 Di-II's wide-to-moderate-telephoto zoom characteristics are prized by experienced photographers. Both versions of the SP 17-50mm F/2.8 stem from the long-successful SP 28-75mm F/2.8—originally designed for 35mm film SLRs. Later refined to meet the needs of high-resolution digital SLRs with APS-C-format sensors, and like its further refined variant (the SP 17-50mm F/2.8 XR Di-II VC, model B005), the 17-50mm renders a picture angle range approximating a 26-78mm lens on a full frame DSLR or a 35mm SLR. A fast and constant F/2.8 maximum aperture benefits photographers in several ways, including the ability to render cluttered backgrounds well out of focus, expanded low-light shooting freedom and a brighter viewfinder image. With its mildly less complex optical formula and without tri-axial VC (Vibration Compensation), the SP 17-50mm F/2.8 Di-II (model A16) stands out as a remarkable value and a favorite of passionate photographers.
Di-II lenses are performance-engineered expressly for digital SLR cameras with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm.
- Enjoy being able to switch from streetscapes and interiors to portraits and headshots, without switching lenses.
- Demand optical performance and handling characteristics designed to meet the needs of professional and experienced non-professional photographers.

The Risk of Purchasing Gray Market Products:
In looking for our products, you may find that products not supplied through our regular channel are sold in your market. Such products are generally called "gray-market products" and may involve quality problems.
Interchangeable lenses are precision optical and mechanical products. Therefore, if handling during transportation or storage is not adequate, defects or malfunctions may occur. As for our products supplied through our regular distribution channel, meticulous care is taken in transportation and storage in order to ensure quality protection. However, in the case of gray-market products, it is more likely that they are handled inadequately during transportation or storage; are exposed to undesirable conditions such as high temperatures, vibration, shock, high humidity, dust, dirt and so on; or that they have been mixed up with used products since they are not under our strict control. Therefore, we are unable to warrant the quality of gray-market products.
Always look for Tamron products that are supplied through our authorized distribution channel. By purchasing Tamron products from an authorized dealer, you can ensure the quality of the product, which will be also covered by Tamron USA's Six-Year Limited Warranty, the only warranty accepted by Tamron USA, Inc. in the USA as of October 1, 2007.
