Nikon 12-24mm f/4G ED IF AF-S DX Nikkor Zoom Lens
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.Focal length: 12-24mmMaximum aperture: f/4Picture angle (Nikon digital SLR): 99 to 61 degreesLens construction: 11 elements in 7 groupsLens drive: Silent Wave MonitorExtra-Low Dispersion (ESD) lens: 2 elementsAspherical lens: 3 elementsFocusing: Internal Focusing (IF) typeMinimum shooting distance: 11.8 inchesMaximum reproduction ratio: 1:8.3Minimum F stop: 22Aperture blades: 7 (rounded)Lens hood: HB-23 (included)Filter size: 77mmIncluded accessories: HB-23 hood, 77mm lens cap, rear capDimensions: 3.2 inches in diameter, 3.5 inches longWeight: 1.07 pounds
