OK this is weird. I have one of each Pentax flash unit (a 540 I've had a while and a brand new 360 I had yesterday), and I can't get either of them into any other sync mode than Auto (leading curtain sync) - what on earth am I doing wrong, or are they BOTH faulty??
I've tried every other setting I can think of - am I missing something simple??? Is this a "wood for trees" problem? I only just decided to try contrast sync.... and can't!!
Anybody - HELP!! Surely they're not both suddenly faulty!?
I can't get anything other than leading curtain either off or on, camera (a K-7).
