[. . . ] No reproduction in any form of this manual, in whole or in part (except for brief quotation in critical articles or reviews), may be made without written authorization from NIKON CORPORATION. [. . . ] 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). 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. â· 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 for the B, E and K screens. The first values are for the PK-11A ring used alone and the other ones for the PK-11A--PK-13, PK-11--PK-13, or PK-1--PK3 rings used together. [. . . ] *** The figures shown here represent the ranges obtained with the subject on the baseplate, using the lens without any close-up attachment. [. . . ]
