[. . . ] , the residual chromatic aberration) across the full 400 to lOOOnm wavelength range, thus ensuring exceptional image sharpness and contrast at all apertures, including full aperture. In fact, the degree of correction obtained enables the elimination of the requirement for corrective refocusing for infrared photography. The application of Nikon Integrated Coating (NIC) to air-to-glass lens surfaces further enhances performance by increasing image contrast and color rendition. [. . . ] To prefocus the lens using the engraved distance scale settings, rotate the focusing/ zooming control ring until the desired camera-to-subject distance setting (as measured or estimated) is lined up opposite the distance scale index line engraved on the lens barrel. In high or low temperatures, the focal length of the lens might be slightly different when compared with what it is in ordinary temperatures. In this case, you can rotate the focusing ring of the lens slightly beyond the infinity position to focus accurately. Recommended focusing screens Various interchangeable focusing screens are available for F2 and F3 Nikon cameras to suit any type of lens or picture-taking situation. Those which are recommended for use with this Zoom-Nikkor ED 180-600mm f/8 lens are listed below.

To facilitate setting the lens at a desired focal length, reference marks corresponding to focal length settings of 180mm, 200mm, 250mm, 300mm, 350mm, 400mm, 500mm and 600mm are provided. , the zone of acceptable image focus) can be checked by reading the curved, color-coded depth-of-field indicators engraved on the lens barrel. The pairs of colored lines on either side of the white distance index line correspond to f/numbers of the same color on the aperture scale. You can also observe the depth of field through the viewfinder by simply pressing the depth-of-field preview button on the camera body. 5 ft) to infinity (°°) Focusing/Zooming control: Via a single control ring; reference marks for focal length settings of 180mm, 200mm, 250mm, 300mm, 350mm, 400mm, 500mm, and 600mm are provided; ring locking screw also provided Aperture scale: f/8 ~ f/32 on both standard and aperture-direct-readout scales Diaphragm: Fully automatic Exposure measurement: Via full-aperture method; meter coupling ridge provided for AI cameras Tripod mounting: Via socket in tripod mounting collar; collar rotatable on lens to permit vertical and horizontal format picture-taking; clickstops provided at each 90° of rotation; collar locking screw provided Attachment size: 95mm (P = 1. [. . . ] €¢ To protect the lens surface from dirt or damage, the use of a UV filter is recommended at all times. €¢ Keep the lens cap in place whenever the lens is not in use. €¢ Attach both the front and rear caps when the lens is stored separately.
