Tokina AT-X 16.5-135 DX, is a 16.5-135mm f/3.5-5.6 AF lens designed exclusively for digital SLR cameras with APS-C sensors.* This lens gives the digital photographer an ultra wide-range zoom lens that has the equivalent angle of view to a 25-200mm.
This Tokina compact super wide zoom range begins at 16.5mm and offers the photographer a wider angle of view than most lenses in its class that start at 18mm. This makes the lens better suited for scenic and travel photography in addition to being a great standard lens for most general photography situations.
The AT-X 16.5-135 DX’s optical design benefits from the latest advances in the industry. Three aspherical elements, one all glass precision-molded element and 2 compound elements yield high contrast. Additionally two Super-low Dispersion (SD) glass elements correct chromatic aberration.
The AT-X 16.5-135 DX has a newly designed high-precision mechanical zoom cam system minimizes play and eliminates zoom creep.
