Neither my 645 or 6X7MLU have a self timer-I hate that. Do any of the Pentax's have it? That's the 645's only flaw in an otherwise near perfect camera in my opinion. It has so many great features-TTL flash, motordrive, darn accurate meter, second tripod socket for verticals, shutter speeds down to 15 sec. The timer drastically reduces the need to use a cable release(and allows yourself in the pic). I've gotten spoiled over Nikon's MC-10/MC-12/MC-30 style of electronic release-hate any other type. I hate cables, I hate wireless remotes
