An f/stop is a number used to represent the amount of light which is allowed to pass through the lens. The diaphragm is the mechanical iris inside the lens which is opened or closed according to the setting of the aperture ring.

The aperture is the hole or opening formed by the diaphragm blades.

•The camera and its FD lenses are designed for automatic exposure with light measurement done at the maximum aperture. Manual stopped-down metering is not recommended with FD lenses. If you wish to set the aperture manually, take the meter reading before removing the aperture ring from the 'A' mark.

G Selecting a Shutter Speed

The amount of light striking the film is controlled by the lens diaphragm, whereas the length of time that light is allowed to strike the film is controlled by the focal plane shutter. The shutter consists of two opaque "curtains" which travel over the opening and allow the light coming through the lens to reach the film. The length of time the curtains remain open determines the exposure time for your picture. On the shutter speed dial, shutter speeds from 1/1000 – 1 sec., and B, are marked in white (with the exception of the orange "125" for electronic flash synchronization), while the speeds from 2 – 30 seconds are marked in yellow. To set the shutter speed, rotate the dial in either direction until the
