Tamron SP 20-40mm F/2.7-3.5 Aspherical IF AF Lens For Nikon
This fast ultra wide-angle zoom is a logical option as a standard lens with its 40mm focal length. Thanks to a large 42.5mm diameter compound aspherical element in the front group, and another aspherical element in the rear group, distortion and somatic aberrations at the wide-angle setting are eliminated. Use of a polarizing filter is possible thanks to the internal focusing system and large 77mm filter diameter. A flower-shape bayonet-type lens hood is supplied as a standard accessory.
