Notes
• Image noise becomes more apparent when using higher sensi-
tivities, particularly on uniform dark areas. Long exposure times
may cause severe image noise. In order to reduce this annoying
phenomenon, the camera will take a second "dark frame" (taken
with the shutter closed) automatically after a shooting with slow
shutter speed and high ISO value. The noise metered in this
parallel image is then digitally "subtracted" from the data for
the actual image. In such cases the message

of the "exposure" time must be taken into account for long-term
exposure times. The camera must not be switched off during that
time. We recommend disabling Noise Reduction to allow shooting
multiple frames in series and to apply noise reduction later during
the post-editing stage. The images will have to be taken in raw
