Using other type 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
information, contact the manufacturer or local supplier of
the flash unit. Also, some studio flash units may not sync
properly and part of the image could be blacked out by
the second shutter curtain. It is recommended, for safe-
ty's sake, to use a shutter speed one step slower than
flash sync speed.
