6. Flash in the individual camera modes
If the mecablitz is switched on and ready for firing,
a flash will be fired each time the camera's shutter
is released. The amount of light is controlled by
TTL.
Triggering lock (only SF1 and SFx)
On the Pentax SFx and SF1 cameras, the flash will
not be fired when the prevailing light is sufficient
for an exposure in normal mode. The exposure is
then completed with the shutter speed indicated in
the display field.
If you intend to take a shot with a shutter speed
faster than e.g. 1/250 sec. (depending on the
camera model) you must switch off the flashgun.
Refer to the camera's operating instructions for
details.
7. Autofocus measuring flash
AF red-light beam
Fig. 5: AF red-light beam
The integrated AF red-light beam of the mecablitz
supports the automatic focusing of autofocus TTL
cameras. When the prevailing light is insufficient
for automatic focusing, the mecablitz will project a
pattern of red vertical stripes onto the subject as
soon as the camera's shutter release is lightly tou-
ched.. The camera's autofocus system then focu-
ses the picture by this striped pattern.
