New Tamron SP AF 11-18mm F/4.5-5.6 Di-II LD ASPHERICAL (IF) lens

Mr. Morio Ono, President of Tamron Co., Ltd., announced the successful development of the SP AF11-18mm F/4.5-5.6 Di-II LD Aspherical (IF) (Model A13), a new high performance ultra wide-angle zoom lens designed exclusively for digital SLR cameras using APS-C size image sensors.

The new SP AF11-18mm F/4.5-5.6 Di-II LD Aspherical (IF), an ultra wide-angle zoom lens, is Tamron's first lens designed for exclusive use with digital SLR cameras using APS-C size image sensors. The lens provides reliable performance in a compact size to meet the needs of digital SLR camera users pursuing creativity in wide-angle 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. "Di (Digitally Integrated design)-II " is the designation Tamron puts on lenses designed for exclusive use with digital (APS-C size) SLR cameras, featuring optical systems optimized to meet the performance characteristics of digital cameras. "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.
