Manual Exposure Control

In the manual exposure mode, you can shoot at any combination of flstop and shutter speed from 1/2000 to 8 sec ., enabling you to select your desired shutter speed. Manual exposure is also required when stop-down exposure measurement is necessary or when you want to use the B, T, or X setting.

Except at the B, T. and X settings, the shutter speed you set is shown in the viewfinder immediately after the shutter release button ® is depressed halfway. As before, the - symbol at the upper right of the number indicates shutter speeds from 1 to 8 sec. Also the letter M appears to the left of the number, indicat- ing the manual exposure mode. Above the M, the following symbols appear : -, +, and - + which indicate underexposure, overexposure, and correct exposure, respectively. To obtain correct exposure, simply turn the shutter speed dial @ andlor aperture ring until the - + symbol appears. The LCD stays on approx . 16 sec. after you remove your finger from the button .

Intermediate settings on the shutter speed dial cannot be used while those on the lens aperture ring ~ can be. Therefore, stop the lens aperture down or open it up to the appropriate inter - mediate setting when fine adjustment of the exposure is necessary.

When making blank exposures with the shutter speed dial set between 11125 and 1/2000 sec. , the shutter fires at 1/80 sec. with M 80 displayed until the frame counter reaches one .

At the B or T setting, an M- appears in the viewfinder.

At X, an M+ 80 appears. However, the + does not mean over- exposure, because the meter does not function at this setting ; as soon as a dedicated Nikon Speedlight is attached to the F3AF and turned on , the + disappears from the display, leaving just M 80.
