This is not unique to the K10D. I tried to use a AF500-FTZ and a AF400T simultaneously on both Z-1 and *istD, connecting as you did with 5P cables. However, my result was the opposite; the FTZ flash fired, but not the T.
I can't give you a good explanation of why this happens, but it seems that the T-series (ie. analogue flashes) can't be triggered together with digital flashes for some reason. One possibility is that the 5P cord relays information between camera and flash in such a way that it excludes one of the flashes from the "conversation" all together. Perhaps the camera has to decide which communication "protocol" it has to use. Have you tried using a 3rd party X-shoe and cable with only the centre-contact connected? Perhaps that disables any "advanced" communication exchange between flash and camera. Alternatively, you can use a slave trigger mounted on the bracket, and connect one of the flashes to the trigger. hth, Jostein 2007/5/27, jim <[EMAIL PROTECTED]>: > I have 2 flashes, a AF360FGZ and a AF280T which I intended to use for macro > work with my SMC Takumar macro 100 plus an extention tube on my K10D. > I made up a flash Bracket at work and used the pentax 5P cables to connect > everything together. > Set both flashes to manual full power only to discover that only the 280T > fired.
