FOREWORD

The Nikkor 13mm f/5.6 is a super-wideangle lens with an optical con- struction of 16 elements in 12 groups. As this unit is a true wideangle lens, it reproduces straight lines accurately and without the pronounced curvature effects common to fisheye lenses. Also, the optics are corrected for evenness of illumination across the full frame, and employ the Nikon close focus correction system (the rear elements are "floating") for optimum performance at the 0.3m (1 ft) minimum focusing distance. The retrofocus- type configuration of the lens enables all normal reflex mirror functions for full thru-the-lens operating convenience. Enhancing the high optical quality of this lens is Nikon Integrated Coating (NIC) on air-to-glass lens surfaces; flare and ghost are fully controlled for excellent image contrast and out- standing color rendition. Included with the lens is a set of four bayonet- mount filters; to attach a filter to the special mount provided at the rear of the lens (one filter must always be in place), simply push the filter into the mount and turn approximately 60° counterclockwise to lock. With its exceptional depth of field and wide picture angle (118°), the Nikkor 13mm f/5.6 can be used indoors and outdoors to achieve unusual and dramatic photographic effects.

The lens offers "automatic maximum aperture indexing" (Al) with suitably- equipped cameras, via the meter coupling ridge provided. The ridge and the auto diaphragm function together to permit full aperture exposure measure- ment; 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.

MOUNTING THE LENS

Fit the bayonet mount on the camera over the bayonet mount on the lens, aligning the index on the lens with the mounting index on the camera. Twist the camera clockwise until it clicks into place.

To remove the lens, press the camera's lens release button and twist the camera counterclockwise.

Note: When using the camera with a meter coupling lever (Al type), make sure that the camera's meter coupling lever is correctly positioned; when using a camera without this lever (non-AI type), "manual" maximum aperture indexing is required. In both cases, refer to the camera's instruction manual.

13mm specifications

Nikon has long been a leader in photography equipment, and their 13mm lens stands out as a powerful tool for both amateur and professional photographers. The Nikon 13mm lens is known for its ultra-wide-angle capabilities, making it an ideal choice for landscape photography, architecture, and astrophotography.

One of the main features of the Nikon 13mm lens is its exceptional field of view. With a focal length of 13mm, it captures stunning perspectives that other lenses cannot. This allows photographers to fit more into the frame, ideal for capturing vast landscapes or intricate architectural details. The lens provides a wide aperture, which not only enhances low-light performance but also creates beautiful depth of field effects, allowing for creative compositions.

The lens incorporates Nikon's advanced optical technologies, including ED (Extra-low Dispersion) glass elements that significantly reduce chromatic aberration. This results in remarkably sharp images with vibrant colors. The inclusion of aspherical lens elements helps to minimize distortion and maintain image quality even at the edges of the frame.

Additionally, the Nikon 13mm lens boasts a robust build quality. It is designed to be weather-sealed, making it resistant to dust and moisture, which is particularly beneficial for outdoor photographers. The focus mechanism is smooth and precise, featuring Nikon's Silent Wave Motor (SWM) technology. This means fast, quiet, and accurate autofocus, allowing photographers to capture fleeting moments without disturbing the surroundings.

The lens's compact and lightweight design enhances portability, making it easier to carry on long shoots or hikes. It is compatible with various Nikon camera bodies, maintaining the company's commitment to versatile and user-friendly equipment. With its wide angle and high-quality optics, the Nikon 13mm lens empowers photographers to push creative boundaries.

Whether you are a landscape enthusiast aiming for sweeping vistas or an architect wanting to capture stunning structures in their entirety, the Nikon 13mm lens is an invaluable addition to your photography toolkit. Its advanced features and technologies make it a top choice for anyone looking to elevate their photographic artistry. In a competitive market, the Nikon 13mm lens represents a perfect blend of quality, functionality, and innovation.
