• SP AF 28-75mm F/2.8 XR Di LD Aspherical [IF] MACRO

Fast, ultra-compact mid-range zoom

High resolution full-frame digital SLRs demand the optical quality for which the SP 28-75mm F/2.8 XR Di is famous. Another in Tamron's selection of fast and constant F2.8 maximum aperture optics, its speed benefits photographers in several ways, including the ability to render cluttered backgrounds well out of focus, added low-light shooting freedom and a brighter viewfinder image. Featuring XR (Extra Refractive Index) and LD (Low Dispersion) glass in an optical formula employing 16 elements and 14 groups—assuring sharpness, optimal contrast and color accuracy, rendering striking images. Sophisticated aspherical element design and internal focus contribute to barrel size that belies a typically large F2.8 optic. With both an ideal picture angle range, fast aperture and outstanding optical properties, it's no wonder that so many SP 28-75mm F/2.8 lenses can be found in the bags of noted wedding and corporate shooters.

The designation “Di” (Digitally Integrated Design) marks a generation of lenses, which have been specially adapted to the higher requirements of digital SLR cameras (APS-C and full frame).
