❚❚ The AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR The AF-S DX NIKKOR 18-105 mm f/3.5-5.6G ED VR is for use exclusively with Nikon DX format digital cameras. Superior optical performance and image rendering are ensured by the use of aspherical lens elements and elements made using extra-low dispersion (ED) glass to correct chromatic aberration. A rounded aperture produces soft, esthetically-pleasing blurring of point light sources in out-of-focus areas of the image (bokeh). If the camera is equipped with an AF-ON button, vibration reduction will not be activated when the AF-ON button is pressed. A Using the Built-in Flash When using the built-in flash, be sure the subject is at a range of at least 0.6 m (2 ft.) and remove lens hoods to prevent vignetting (shadows created where the end of the lens obscures the built-in flash). Camera D5000, D3100, D3000 D700, D7000, D300 series, D200, D100, D80 D90, D70 series D50 D60, D40 series Zoom position 18 mm 24 mm Minimum distance without vignetting 2.5 m/ 8 ft. 2in. 1.0 m/ 3 ft. 3in. All No vignetting at any focus distance 18 mm 24 mm 18 mm 24 mm 18 mm 24 mm 35 mm 1.5 m/ 4 ft. 11in. No vignetting at any focus distance 1.0 m/ 3 ft. 3in. No vignetting at any focus distance 2.5 m/ 8 ft. 2in. 1.0 m/ 3 ft. 3in. No vignetting at any focus distance Because the built-in flash units for the D100 and D70 can only cover the angle of view of a lens with a focal of 20 mm or more; vignetting will occur at a focal length of 18 mm. D Lens Care • Keep the CPU contacts clean. • Use a blower to remove dust and lint from the lens surfaces. To remove smudges and fingerprints, apply a small amount of ethanol or lens cleaner to a soft, clean cotton cloth or lens-cleaning tissue and clean from the center outwards using a circular motion, taking care not to leave smears or touch the glass with your fingers. • Never use organic solvents such as paint thinner or benzene to clean the lens. • The lens hood or NC filters can be used to protect the front lens element. • Attach the front and rear caps before placing the lens in its flexible pouch. • When a lens hood is attached, do not pick up or hold the lens or camera using only the hood. • If the lens will not be used for an extended period, store it in a cool, dry location to prevent mold and rust. Do not store in direct sunlight or with naphtha or camphor moth balls. • Keep the lens dry. Rusting of the internal mechanism can cause irreparable damage. • Leaving the lens in extremely hot locations could damage or warp parts made from reinforced plastic. n 316
