Standard Manual Focus Wide angle Lens
For Landscapes and General Photography

Nikon 28mm f/2.8 AIS Manual Focus LensConsisting of 8 elements in 8 groups, this retro-focus wide-angle lens is lightweight and compactly designed. Spherical and coma aberrations are well corrected to ensure uniformly sharp images of high contrast over the entire film plane even at full aperture.

Adopting the Nikon’s Close-Range Correction System, this lens also offers high performance even in close-up shooting. In addition, the application of multilayer anti-reflection coating (known as Nikon Integrated Coating, or NIC) on air-to-glass surfaces minimizes flare and ghost, making for improved contrast and neutral color rendition.

The lens offers “automatic maximum aperture indexing” (Al) with suitably equipped cameras (except F-401/N4004*), via the meter coupling ridge provided. The ridge and the auto diaphragm function together permit full aperture exposure measurement ; the lens is also fitted with a meter coupling shoe to permit the same operation with Nikon cameras which lack the Al facility.

An “aperture-direct-readout” scale is engraved on the lens to allow direct reading of the aperture setting in suitably equipped camera finders. The fast lens speed of f/2.8 makes picture framing, composing and focusing easy. The lens is especially suitable for architectural photography and other applications where special effects are desired. *The Nikon N4004 is sold exclusively in the U.S.A.

• When mounting the lens on a camera body with a meter coupling lever (Al type), make sure that the lever is correctly positioned; when mounting on a camera body without this lever (non-Al type), “manual” maximum aperture indexing is required. In both cases, refer to the camera's instruction manual.

• When the lens is used with the Nikon F-401/N4004, the camera meter coupling function does not operate and the exposure indicator LEDs do not appear. Recommended Focusing Screens (see the reverse) Various interchangeable focusing screens are available for Nikon F6-,F5-,F4- and F3-series cameras to suit any type of lens or picture-taking situation. Those which are recommended for use with this lens are listed in the table  For details, also refer to the specific camera's instruction manual.

Lens Care

• Clean lens surface with a blower brush. To remove dirt and smudges, use a soft, clean cotton cloth or lens tissue moistened with lens cleaner (separately available). Wipe in ca circular motion from center to outer edge, taking care not to leave traces and not to touch the other lens parts. • To protect the lens surface from dirt or damage, the use of an NC filter is recommended at all times. The lens hood also helps to protect the lens.

• To protect the lens surface from dirt or damage, replace both the front and rear caps whenever the lens is not in use. • Do not splash water on the lens or drop it in the water because this will cause it to rust and malfunction.

• If you will not use the lens for a long time, protect it from rust and mold by storing it in a cool, dry place. Also, do not store in direct sunlight, and keep it away from naphthalene or camphor.

• Reinforced plastic is used for some parts of the lens exterior; to avoid damage, never leave the lens in an excessively hot place.

Features

AI-S - The descendant of AI, AI-S lenses added a pair of mechanical features necessary for both automatic and semi-automatic exposure functions of the Nikon F4, F501/N2020, F301/N2000 and FA camera

AI - Manual focus lens featuring "Automatic Indexing" light meter connection, unveiled in 1977. Supplementing the pre-AI meter prong, also an AI lens adds a ridge to the aperture ring that programs the aperture setting in relation to the maximum aperture,

CRC - Close-Range Correction is another Nikon extremely significant focusing break-through, as it allows advanced image perfection at close focusing range and expands the focusing distance.

FX-format
The leading factor setting the Nikon FX apart from other sensors is the large size of the pixels, which allows for more light collection.

• 74-degree picture angle for superlative flexibility.

• Compact, lightweight wide-angle lens.
