Focal Length - Nikon D3200 Reference Manual

II TheAF-SDXNIKKOR 18-55mm f/3.5-5.6G VR
The AF-S DX NIKKOR 18-55mm f/3.5-5.6G VR is for use exclusively with Nikon DX
format digital cameras. In the case of the AF-S DX NIKKOR 18-55 mm f/3.5-5.6G VR,
changes to zoom can alter maximum aperture by up to 1 1/3 EV. The camera however
automatically takes this into account when setting exposure, and no modifications to
camera settings are required following adjustments to zoom.
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).
Because the built-in flash units for the DIO0 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.
I_ 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.
