The 18-300mm f/3.5-5.6G ED VR (not to be confused with its less-expensive alternative, the 18-300mm f/3.5-6.3G ED VR) is a telephoto superzoom lens manufactured by Nikon for its line of DX DSLR cameras. 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; 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.
