Tamron SP AF 90mm F/2.8 Di Macro

Manufacturer description: The SP 90mm F/2.8 Di enjoys enviable DNA from Tamron's original SP 90mm F/2.8, further refined for the demands of high-resolution digital imaging. Extraordinary 1:1 (life-size) close up capacity, combined with what many consider an ideal portraiture focal length (when used on full-frame DSLR or 35mm SLR cameras) this prime optic was nicknamed "the portrait macro." Equally at home on APS-C DSLRs, rendering a picture angle equivalent of the 140mm lens on a full-frame DSLR or 35mm SLR camera, photographers appreciate the resulting increase in front element-to-subject distance and close-up photography. In addition, this 135mm-like picture angle is well-suited for environmental portraiture. Extraordinary sharpness, striking contrast and a remarkable absence of distortion combine to produce images of exceptional caliber.
