Front-Curtain Sync

The flash fires an instant after the front curtain of a focal plane shutter has completed its travel across the film plane. This is the way the F5 operates with the flash sync mode at Normal Sync. (See “Rear-Curtain Sync”.)

ISO film speed

The international standard for representing film sensitivity. The higher the number, the greater the sensitivity, and vice versa. A film speed of ISO 200 is twice as sensitive as ISO 100, and half that of ISO 400 film.

G-type AF Nikkor lenses

G-type AF Nikkor lens has no aperture ring; aperture should be selected from camera body. Unlike other CPU Nikkor lenses, aperture does not need to be set to minimum (largest f- number). G-type AF Nikkor lenses send Distance Information to the F5’s microcomputer. Used for 3D Color Matrix Metering or 3D Multi-Sensor Balanced Fill-Flash (with Nikon SB-50DX/ SB-28/SB-28DX/SB-27/SB-26/SB-25 Speedlight).

Guide number

The guide number indicates the power of a flash in relation to ISO film speed. Guide numbers are quoted in either meters or feet. Guide numbers are used to calculate the f/stop for correct exposure as follows:

guide number

f/stop = ———————————

flash-to-subject distance

Using a selected aperture, we can calculate the required flash- to-subject distance with the formula:

guide number

flash-to-subject distance = ———————

f/stop

Useful for determining the maximum flash-to-subject distance for flash photography.

LCD

Liquid Crystal Display. The F5 has three: the panels on top and at the rear of the camera body, and inside the viewfinder.

Manual flash

Flash output is controlled manually in manual flash mode, unlike in auto flash mode, where flash output power varies automati- cally according to the selected aperture. Some Speedlights, including the Nikon SB-50DX, SB-28/28DX, SB-27, SB-26, SB- 25, SB-24 and SB-20, provide selectable manual outputs (full, 1/2, 1/4, 1/8, 1/16, etc.), while others provide full manual output only.
