[. . . ] 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 outstanding color rendition. Included with the lens is a set of four bayonetmount 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.

The image on the film, however, shows no trace of this. Note: Light transmission properties vary somewhat with focusing screen type, thus occasionally requiring exposure correction to compensate for the combined effects of the lens/screen/camera combination in use. The numbers listed in certain columns of the combination table above (i. , —1 and — H) denote the amount of correction necessary in f/stops. To adjust the camera's Photomic finder for the indicated f/stop correction, lift and turn the film-speed index ring until the ASA/ISO value for the film in use is aligned with the appropriate mark engraved on the ring. In the example figure shown, ASA/ISO 100 is aligned with the —'/2 mark to provide the correction required when using the Type H2 screen with a Photomic finder-equipped F2 Nikon camera and mounted Nikkor 13mm f/5. LENS USE • Due to the unique optical construction and wide picture angle of the Nikkor 13mm f/5.
