my first and second message did not make it :-(
Hi Jens thanks to your advice I had an eye for a slave flash and found a barely used Osram 18 SC servo (with sensor) in a second hand store for nearly nothing together with some nice filters and other accessories. Since I can not find a free copy of the manual an the internet and since there is really no switch to set anything on this flash, could you explain for me: What does this "servo" mean in addition to the slave function, what's the difference to the non servo model? Do I have to care about anything when using it together with the AF280T from Pentax as main flash? I assume the Osram will always flash at full power and the main flash will control the amount of light? I think you told me that you have exact the same flash combination used successful with analog bodies. Is 18 the guide number for ISO 100? thanks in advance a (today) very happy Markus
