THIS IS SERIOUS! Warning: the Pentax flash owners or adaptable pentax.Car the contacts on the receiver (where the flash is attached) do not match those of Pentax and you could "screw up" your flash. Indeed, the reception of this trigger, I obviously tested with my Pentax flash since it is supposedly compatible (written) and ho! surprise the flash is set SHORT CIRCUIT: it could not load and no possible remote control, I quickly unplugged before it fumme Feeling is a problem, then I turned back my flash (but empty this time, open-flash way of course!) zoom and began to make a mournful sound without charge, SEA ..! uh, he died THIN! I turn it off, and after a prayer for the deceased, I turn back without the great hope and miracle it works again! OUF ... if I had persevered in my essay, it serait'il past ...? I also own a Canon flash, I plugged the shutter button and there: perfect, this remote control works very well and has not suffered the first run, so I can return it. On the packaging there are pictures of different models, looking good, I say GOOD! we can notes that the model that seems to suit the Pentax contacts is Kaavie 4 PT-04 N2, N2 and I say Non NE. But this model seems not found on the net, can you help me find it ???
