Manual Program Shift
With the
OM77AF
, the photographer is free to select
a desired aperture or shutter speed with the assur-
ance of a perfect exposure. For instance, when
using a 50 mm F1.8 AF lens, the initial setting of
aperture and shutter speed is in accordance with
the Standard Program (Program chart ). By using
the shift-knob, the photographer is free to shift the
program line by 1/2-stops to reach
a desired shutter
speed or aperture. In this way, and with no need of
any physical adjustment, the program can be used
as an aperture or a shutter speed-preferred program,
depending on the photographer's intention.
