II TheAF-SDXNIKKOR 18-105 mm f/3.5-5.6GED 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.
M 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 Zoom position Minimum distance without vignetting
D5000, D3100, D3000
18 mm 2.5 m/ 8 ft. 2 in.
24 mm 1.0 m/ 3 ft. 3in.
D700, D7000, D300 series,
D200,D100, D80
All No vignetting at any focus distance
D90, D70 series
18 mm 1.5 m/ 4 ft. 11 in.
24 mm No vignetting at any focus distance
D50
18 mm 1.0 m/ 3 ft. 3in.
24 mm No vignetting at any focus distance
D60, D40 series
18 mm 2.5 m/ 8 ft. 2 in.
24 mm 1.0 m/ 3 ft. 3in.
35 mm 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.
C 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 foran 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.
