S. A. only. M/A (Autofocus with Manual Override) To focus using autofocus with manual override (M/A): z Slide the lens focus-mode switch to M/A. x Focus. If desired, autofocus can be over-ridden by rotating the lens focus ring while the shutter-release button is pressed halfway (or, if the camera is equipped with an AF-ON button, while the AF-ON button is pressed). To refocus using autofocus, press the shutterrelease button halfway or press the AF-ON button again. ¦ Depth of Field The depth-of-fi eld indicators on the lens show the approximate depth of fi eld. If the camera off ers depth-of-fi eld preview (stop down), depth of fi eld can also be previewed in the viewfi nder. See the depth of fi eld table for more information. 1.5 7 4 2 0.8 Focus distance mark Depth-of-fi eld indicators ¦ Aperture Aperture is adjusted using camera controls. ¦ Built-in Flash Units When using the built-in fl ash on cameras equipped with a built-in fl ash unit, shoot at ranges of 0.6 m (2 ft) or more and remove the lens hood to prevent vignetting (shadows created where the end of the lens obscures the built-in fl ash). ¦ The Lens Hood The lens hoods protect the lens and block stray light that would otherwise cause fl are or ghosting. Attaching the Hood Align the lens hood mounting mark (.) with the lens hood alignment mark ( ) and then rotate the hood (w) until the . mark is aligned with the lens hood lock mark (—.). When attaching or removing the hood, hold it near the symbol on its base and avoid gripping it too tightly. Vignetting may occur if the hood is not correctly attached. The hood can be reversed and mounted on the lens when not in use. ¦ Focusing Screens The following cameras support a variety of focusing screens for use in different situations. Screen Camera A B C E EC-B EC-E G1 G2 G3 G4 J L M U F6 . . — . — — — — — . . . F5+ DP-30 . . . . . . . . F5+ DA-30 . . . . .

( ): Figures in parentheses give the exposure compensation for center- weighted metering. Select “Other screen” for Custom Setting b6 (“Screen comp.”) when adjusting exposure compensation for the F6; note that with screens other than B or E, “Other screen” must be selected even when the value for exposure compensation is 0. Exposure compensation for the F5 can be adjusted using Custom Setting 18; see the camera manual for details. Empty cell: Not suited to use with this lens. Note that type M screens can however be used for photomicrography and macro photography at magnifi cations of 1 : 1 or higher. Note: The F5 supports matrix metering with A, B, E, EC-B/EC-E, J, and L focusing screens only. ¦ Lens Care • Do not pick up or hold the lens or camera using only the lens hood. • Keep the CPU contacts clean. • Should the rubber lens-mount gasket be damaged, cease use immediately and take the lens to a Nikon-authorized service center for repair. • Use a blower to remove dust and lint from the lens surfaces. To remove smudges and fi ngerprints, 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 fi ngers. • Never use organic solvents such as paint thinner or benzene to clean the lens. • The lens hood or NC fi lters can be used to protect the front lens element. • Attach the front and rear caps before placing the lens in its fl exible pouch. • 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. ¦ Supplied Accessories • 58 mm snap-on Front Lens Cap LC-58 • Rear Lens Cap LF-4 • Bayonet Hood HB-47 • Flexible Lens Pouch CL-1013 ¦ Compatible Accessories • 58 mm screw-on fi lters ¦ Specififi cations Type Type G AF-S lens with built-in CPU and F mount Focal length 50 mm Maximum aperture f/1.8 Lens construction 7 elements in 6 groups (including 1 aspherical lens element) Angle of view • Nikon fi lm SLR and FX-format D-SLR cameras: 47° • Nikon DX-format D-SLR cameras: 31° 30.
