Originally posted by Kobie When mounting the flash, make sure camera and flash are off, turn on the camera and half press shutter while you turn on the flash. Once the flash "ready light" is on let go of the half press.
Originally posted by rawr Good point. It's necessary - others eg Metz also recommend this as a trouble-shooting step - for example with the 52AF-1 flash:
Wow, this thread in enlightening. Pentax-brand, Pentax-compatible Sigma, and compatible Metz for which I have manuals* don't include that step, though it may make sense if the flash has gone to "sleep" without confirming that a camera is present. All dedicated Pentax flash may require a "tap" on the shutter release to initiate or refresh the data link and/or flash ready status, but this is the first I have read of the need to half-press while powering on a flash. That being said, if Shanny requires it, then so be it!
