User manual NIKON AF NIKKOR 50MM F-1.8D

[. . . ] You are now the proud owner of the AF Nikkor 50mm f/1. 8D, a lens that will provide you with years of exciting picture-taking opportunities. [. . . ] : Acceptable focusing The in-focus image in the central spot may prove to be slightly out of focus on film. When using screens other than type B or E, "Other screen" must be selected even when the required compensation value is "0" (no compensation required). See instruction manual of the camera body for more details. Since type M screen can be used for both macrophotography at a 1:1 magnification ratio and for photomicrography, it has different applications than other screens. When using the B/B2/B3, E/E2/E3, and K/K2/K3 focusing screens in cameras other than those listed above, refer to the columns on the F4 + DP-20's B, E and K screens, respectively. For programmed auto or shutter-priority auto exposure shooting, use the minimum aperture lock lever to lock the lens aperture at f/22. 1 Set the lens to its minimum aperture (f/22) by aligning it with the aperture index. 2 Slide the lock lever toward the aperture ring, so the two orange dots are aligned. To release the lock, slide the lever in the opposite direction. Taking flash pictures with cameras with a built-in flash All Nikon cameras with a built-in flash are usable and no vignetting occurs. To remove dirt and smudges, use a soft, clean cotton cloth or lens tissue moistened with lens cleaner. Wipe in a circular motion from the center outward. [. . . ] the Macro Adapter Ring BR-3 is used to connect the reverse lens to the copying adapter. The figures shown here represent the ranges obtained with the subject on the baseplate, using the lens without any close-up attachment. [. . . ]
