Tamron A16 SP 17-50mm f/2.8 Di II LD Aspherical (IF) Canon Mount Lens
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 compact size and unmatched sharpness the SP 17-50mm F/2.8 Di-II (model A16) stands out as a remarkable value and a favorite of passionate photographers.
