Nikon S2J00200401 user manual AF Micro Nikkor Lenses, Shutter-Speed and Aperture Lock

AF Micro Nikkor Lenses

When the sub-command dial is used to set aperture, the exposure ratio need not be taken into account provided that an external exposure meter is used. Compensation that takes the exposure ratio into account is only necessary when the lens aperture ring is used.

Shutter-Speed and Aperture Lock

Shutter-speed and aperture can be locked at the selected setting ( pg. 94).

12—Assign Command Dial ( pg. 166)

This setting can be used to reverse the roles of the command dials so that the main command dial controls aperture while shutter speed is assigned to the sub-command dial.

22—Aperture Setting ( pg. 173)

Use this setting when you want to adjust aperture using the lens aperture ring. Note that aperture for type G lenses is always set using the command dials, regardless of the option chosen for Custom Setting 22.
