User manual NIKON AF DX FISHEYE-NIKKOR 10.5MM F-2.8G

[. . . ] Before using this lens, please read these instructions. 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. [. . . ] 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 the optional photo finishing software, Capture NX/Nikon Capture 4, powerful digital postproduction tools, 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 the software. 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. 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. Then insert it into the filter holder at the back of the lens.
