Operating Instructions

Depending on the available light, the camera
controls the exposure of the ambient and flash
light as follows:
a) TTL full flash in poor lighting conditions
In poor lighting conditions, e.g. inside a dark
room, where a combination of automatically con-
trolled shutter speeds (depending on the focal
length used) and the largest aperture setting will
not result in a correctly exposed photograph, the
camera automatically selects f/5.6 and a shutter
speed that is appropriate for the focal length
being used (according to the rule of thumb
for blur-free free hand photographs = 1/focal
length, e.g. 1/60s with the Macro-Elmarit-R
60mm f/2.8*) up to the sync speed of 1/250s
and controls the flash as the main light. This
results in a "normal” flash photograph.
*The focal length-adjusted shutter speed setting requires the
use of lenses with a contact strip, i.e. ROM capability (see
"Attaching and removing the lens” and "Use of existing lenses
and accessories”, p. 127 and 128). For lenses with no ROM
capability, the camera always uses 1/250s in the cases described.
