Not compatible with 35mm or FX-format "full-frame" digital SLR cameras. AF not supported by D40 and D60 cameras.
The Tamron AF11-18mm f/4.5-5.6 Di-II LD Aspherical (IF) is an ultra wide-angle zoom lens designed exclusively for digital SLR cameras using the more compact (APS-C) digital size image sensors. The focal length of this lens is equivalent to approx. 16.5-27mm in 35mm format. The lens provides reliable performance in a compact size to meet the needs of digital SLR camera users pursuing creativity in wideangle photography.
The lens uses a new optical system specially designed for digital SLR cameras, in addition to the use of a glass-molded aspherical element having a large clear aperture, hybrid aspherical elements, and elements using such special glass materials as high index/high dispersion glass and low dispersion optical glass, for outstanding optical performance.
Note: Di-II lenses cannot be used with digital SLR cameras using image sensors that are larger than that of an APS-C size imager, or with 35mm film SLR cameras.
Note! AF not supported by D40 and D60 cameras.
