My first Hassie is a 500CM, and I had no trouble firing it with any cable release at hand. But when I added a 501CM, I began having trouble, sometimes not firing at all, other times releasing the shutter okay but not completing the rest of the cycle; I would have to fiddle with the cable release and/or shutter button a bit to get it to finish. A long-throw cable release solved the problem. I believe the one that I am using now is a Linhof, but I also have another brand that works as well. Sorry, I do not recall that brand.
