Using other types of a flash
•
Use of non-Pentax flash units may damage the camera.
For the best results, use a Pentax dedicated flash unit.
•
Some large studio type flashes may have reversed con-
tacts and may not fire with the 645
NII
camera. For further
information, contact the manufacturer or local supplier
of the flash unit. Also, some studio flash units may not
be synchronized properly and a part of the image could
be blacked out by the second shutter curtain. It is rec-
ommended, for safety's sake, to use a shutter speed
one step slower than the flash sync speed.
