Hi Godfrey a good tip, thanks, I will try that. I will often use manual macro lenses for that so it could be a solution. I will try with my smaller Metz 20BC6 as well and have reduced it's output with white plastic on the reflector. thanks Markus

There is one way to disable pre-flash with the built in flash unit on the Pentax *ist DS/DL/DS2/DL2, K100D, K110D and K10D: - Fit a K/M-mount, A-series or any AF series lens with an aperture ring. - Take the aperture ring off the "A" setting on any lens so equipped. Now the built-in flash will operate at full output, un-metered, no pre-flash. You set exposure by setting the camera to manual mode and using the guide number chart listed in the instruction booklet. If you want to use it purely to trigger slaves, get a bit of deep red gelatin filter and cover the popup flash unit with it. Can't do this with DA series lenses as they are in automatic mode 100% of the time. If you're operating with a bunch of external, simple slave activated flash units, however, there's no real downside to it other than the battery drain.
