Additional information:

The Tamron SP AF  11-18 mm  f/ 4.5-5.6  Di II LD Aspherical (IF) A13 (Model A13) is a wide-angle zoom lens  for digital SLR APS-C (max. 16 x 24 mm) cameras.

The lens employs an extended focal length of 17 mm (small format equivalent) preferred by professional users of DSLR cameras.

In order to minimize chromatic aberrations  along the axis and at the borders of the frame the Tamron SP AF 11-18mm f/4.5-5.6 Di II LD Aspherical (IF) lens utilizes one HID (High Dispersion) and one LD (Low Dispersion) glass elements.

 

The precise 7-blade aperture, one molded and two hybrid aspherical elements compensate for spherical and chromatic aberration and distortion, which ensures perfect optical performance of the lens.
