PHOTOGRAPHY
▸ Ensure that the film sensitivity set on the ISO setting dial matches
the sensitivity of the inserted film
▸ Cock the shutter as needed (see p. 31)
▸ Specify the image field (see p. 31)
▸ Tap the shutter button
• The exposure meter is activated and the light balance appears
in the rangefinder. Once the shutter button is released, the
exposure meter remains active for another approx. 14 s and the
light balance remains visible.
▸ Determining the correct exposure (see p. 35)
• It may be necessary to temporarily change the image section
(highly center-weighted exposure metering) or apply a correction
(see p. 36).
▸ Set the desired combination of shutter speed and aperture value
• In addition to the correct exposure, various picture layout con-
siderations like depth of field and the impression of movement
play an important role.
▸ Use the focus ring to manually focus on the object
• It may be necessary to temporarily change the image section,
because the metering field is in the center of the image.
▸ Specify the final image section
▸ Shutter release
• Exposure metering ends and the light balance disappears.
ISO SENSITIVITY
The expected shooting conditions and intended use of the images
play a role in choosing the right film sensitivity.
– Low sensitivity offers sharper and more finely grained results.
– High sensitivity allows shooting at low lighting or with shorter
shutter speeds (e.g. for sports photography).
The sensitivity of the film used must be set via the ISO setting dial
to ensure a correct exposure metering function. The film sensitivity
settings are stated in ISO and degrees. Choose a sensitivity between
ISO 6/9° and ISO 6400/39° at one of the click points.
▸ Turn the ISO setting dial until the triangular index points to the
correct value.
• Opposite values indicate the same film sensitivity in ISO or in
degrees (DIN).
