Like all DX format lenses, the smaller image circle makes it usable on APS-C-sized image sensors only. If used on a 35mm film SLR or older FX DSLRs, vignetting will occur;[3] however, the lens can be used on a modern FX DSLR because the camera can be automatically or manually set to "DX Crop Mode", eliminating vignette, but also reducing the image area from an FX-size sensor to a DX-size sensor.[4]
Much like its counterpart, the lens is designed to be an all-in-one solution to eliminate a photographer's need to change lenses in different scenarios and reduce the amount of gear the photographer needs to carry.[5] The main differences from the f/3.5-6.3G are its heavier (830 g/29.3 oz. vs. 550 g/19.4 oz.), larger (length 120 mm/4.7 in. vs. 99 mm/3.8 in.) (diameter 83 mm/3.3 in. vs. 78.5 mm/3.0 in.), it takes larger filters (77 mm vs. 67 mm), and its aperture is slightly faster (5.6 vs. 6.3).[6][7]
The lens (and the f/3.5-6.3G, since it has the same focal length) has the largest zoom range of any other lens (interchangeable camera lenses only) currently manufactured.[1]
Features edit
The lens is equipped with the following features:[8]
Nikon's Silent Wave Motor for quick and almost completely silent autofocus operation (denotes the "AF-S" on the lens body).[9]
VR II[10] for image stabilization and has two stabilization modes for different conditions (denotes the "VR" on the lens body).
Nikon's Extra-low Dispersion (ED) glass to remove chromatic aberrations (denotes the "ED" on the lens body).[11]
Aspherical elements to remove other kinds of aberrations that may occur.[12]
Lens elements are made with Nikon's multiple layer Super Integrated Coating (SIC) for improved color in photographs as well as reducing ghosting and flaring.[13]
Nikon's Internal Focusing (IF) to prevent the lens from changing size during focusing operation.[14]
