Nikon AF-S DX Nikkor 12-24 mm f/4g zoom zoom if-ed con enfoque automático para cámaras Nikon DSLR

Amazon.com Enjoy a wider angle of view with the Nikon 12-24mm autofocus zoom lens, which is optimized for Nikon digital SLR cameras. The lens offers such features as a 2x zoom ratio, an exclusive Silent Wave Monitor that allows for accurate and quiet high-speed autofocusing, two Extra-Low Dispersion (ED) glass elements for minimized chromatic aberration, and three aspherical lens elements for low distortion. Nikon's D-type design, meanwhile, provides precise distant information for the flash and ambient light exposure processes. Perhaps the nicest feature, however, is the small image circle--the size of the image that's projected by the lens onto the sensor--which produces an optimal image from the center to the edge to the corner. Other details include a variable angle of view from 99 degrees (at 12mm) to 61 degrees (at 24mm), a rounded diaphragm that makes out-of-focus elements appear more natural, and an 11.8-inch close focus distance throughout the zoom range. All Nikon lenses carry a five-year warranty.
