"The SP AF17-35mm F/2.8-4 Di is TAMRON's new ultra-wide zoom lens featuring lan ultra-wide focal length of 17mm considered ideal for Digital SLR use.
Since most Digital SLRs have APS-C sized sensors, the angle of view is narrower than that of conventional SLRs making the typical wide end of wideangle zooms insufficient for many applications.
Accordingly, there is an increasing demand for lenses with an ultra-wide angle of view to compensate for the imager multiplier factor. At the same time, ultra-wideangle lenses are well accepted for use with conventional SLRs for their ability to add an interesting twist to photographic expression.
SP Super Performance is a line of high performance lenses featuring high design specifications. Di: Digitally Integrated Design by Tamron uses optical systems designed to meet the performance characteristics of digital SLR cameras.
