you can use your D80 built in flash to trigger the mecablitz 32Z-1 flash, but you need to get a optical slave to attach to your mecablitz 32Z-1 flash. but make sure the built in flash must able to "see" the receiver (slave)
or you can get two hotshoe adaptors, one for the camera and one for the flash, connect both together via a PC sync cable, cos I don't think D80 and the flash have a PC sync terminal.
do note your flash will work on A* or manual modeit only
* will work on A mode if only one flash is using, or the auto sensor does not see flash light from another flash.
