English Deutsch Francais Introduction Thank you for purchasing the AF DX Fisheye-Nikkor ED 10.5mm f/2.8G. Optical performance of DX Nikkor lenses is optimized for the Nikon D2H, D1-Series, D100 and D70 by reducing the size of the image circle as compared with normal 35mm lenses. This results in lenses with reduced weight and more compact size for much easier handling. • DX Nikkor lenses are specially designed for use with Nikon Digital SLR cameras (D2H, D1-Series, D100 and D70). These lenses can be attached to film-based 35mm SLRs, but will not work properly due to the reduced size of the image circle. Before using this lens, please read these instructions and the notes on safety operations in your camera’s instruction manual. Also, keep this manual handy for future reference. Major features •The DX Fisheye-Nikkor lens is specially designed for use with Nikon digital SLR cameras. It features a 180° angle of view as measured across the diagonal of the frame and provides highquality images from infinity to the closest focusing distance of 0.14m (0.5 ft.), due to Nikon’s original near-distance correction system. •More accurate exposure control is possible when this is mounted on a Nikon camera having 3D Matrix Metering capability, because subject distance information is transferred from the lens to the camera body. •The use of an extra-low dispersion (ED) lens element ensures superb optical performance, while a 7-blade diaphragm produces an aperture that is nearly circular for excellent rendering of out-offocus highlights. Setting the aperture Because this lens does not have an aperture ring, you must set the aperture on the camera body. Focusing and depth of field •With D2H, D1-Series, D100 and D70 digital SLR cameras, both autofocus and manual focus are possible. To focus manually, rotate the focus ring until the image in the viewfinder appears sharp and clear. •If your camera has a depth of field preview (stop-down) button or lever, depth of field can be observed while looking through the camera viewfinder. It is also possible to determine the depth of field by using the depth-of-field table. Getting good results with autofocus Refer to “Notes on using wide or super-wide angle AF Nikkor lenses” on the back of this sheet. Composing (Fig. A) Using a fisheye lens requires much more thought about picture composition than with a conventional lens. This lens not only produces extreme barrel distortion but also exaggerates the relative size of objects to conform to its format: objects near the center appear larger than those at the edges and they show less barrel distortion. The entire field of view is pushed into the distance and spatial relations are transformed, and with a slight shift of the camera, new distortions are created. Be careful not to accidentally include unwanted objects in the picture, such as the legs of your tripod or your own hands or feet. •Use optional Nikon Capture (4), a powerful digital postproduction tool, to convert the images taken by this fisheye to the regular wide-angle lens projection system. For more details, see the instruction manual provided with Nikon Capture 4. •Slight vignetting may occur in the four corners of the frame when shooting at its closest distance or minimum aperture. Taking flash pictures with cameras having built-in flash Avoid taking flash pictures with cameras having a built-in flash, because the flash will not cover this lens’s 180° picture angle. Filters (Fig. B) A regular filter cannot be attached to the front of the lens. Use a gelatin filter by cutting it to an appropriate size as shown in Fig. B. Then insert it into the filter holder at the back of the lens. Rotate the focus ring to the infinity (.) setting to make insertion easier. Lens care •Be careful not to soil or damage the CPU contacts. •Clean the lens surfaces with a blower brush. To remove dirt and smudges, use a soft, clean cotton cloth or lens tissue moistened with ethanol (alcohol) or lens cleaner. Wipe in a circular motion from center to outer edge, taking care not to leave traces or touch other parts of the lens. •Never use thinner or benzene to clean the lens as this might damage it, result in a fire, or cause health problems. •When storing the lens in its lens case, attach both front and rear caps. •When the lens will not be used for a long time, store it in a cool, dry place to prevent mold. Also store the lens away from direct sunlight or chemicals such as camphor or naphthalene. •Do not get water on the lens or drop it in water as this will cause it to rust and malfunction. •Reinforced plastic is used for certain parts of the lens. To avoid damage, never leave the lens in an excessively hot place. Supplied accessories •Exclusive front lens cap •Rear lens cap LF-1 •Flexible lens p...
