The Nikon AF-S DX NIKKOR 17-55mm f/2.8G IF-ED is a high-performance, wide-angle to standard zoom lens designed exclusively for Nikon's DX-format digital SLR cameras. With a constant maximum aperture of f/2.8, this lens is particularly useful in low-light situations and provides a shallow depth of field for creative portraits. The 17-55mm focal length range is equivalent to 25.5-82.5mm in the 35mm format, making it a versatile choice for a variety of photographic applications, including landscapes, photojournalism, and everyday photography. The lens features a Silent Wave Motor (SWM) for fast, quiet, and accurate autofocus, and Internal Focusing (IF) design that keeps the lens compact and the front element from rotating, which is convenient when using polarizing filters. The optical design incorporates three Extra-low Dispersion (ED) glass elements to minimize chromatic aberrations and three aspherical lens elements to reduce distortion, ensuring high resolution and contrast throughout the zoom range. The Super Integrated Coating (SIC) minimizes flare and ghosting, resulting in sharp, clear images with excellent color balance. Built to professional standards, the lens has a rugged construction with dust and moisture resistance, making it a reliable tool for photographers working in challenging environments. Its nine-blade rounded diaphragm creates a natural-looking blur for out-of-focus elements, enhancing the aesthetic quality of the images.
