Manual Control of Aperture
For manual control of the aperture, release
the aperture ring from the "A" position. The
shutter speed and f/stop can be freely set for
achieving specialized technical effects. With
the Canonet G-III 17, special effects in high
tone or low tone can be obtained in the same
manner as with more professional cameras.
• In manual exposure control, the position
of the exposure indicator is in the upper
red mark.
