I cannot for the life of me get this thing to fire as an optical slave using the pentax built in flash. Ive set them to the same channel set the pentax to fire control flash but the canon wont fire. Any ideas?

Don't bother. Canon and Pentax each use a different language. The Canon flash doesn't understand the strobe from the Pentax flash.

Well crap. I borrowed this flash for a shoot tomorrow and I guess it didnt even occur to me that it wouldnt work.

Will using it on camera damage my pentax in anyway? I read somewhere that canon flashes are very low voltage so most likely no. I just wont have an control on the camera but the speedlight has a manual mode I can play with.

just use it on the hotshoe

or go buy some chinese radio triggers/receivers, they're extremely affordable anyway.
