Dear Friends, Thank you all for your comments and suggestions. It is, unfortunately, a little late to suggest asbstinence from Pentaxforums; I am already a long time member ;)
Seriously though, thank you all (especially John) for insisting on the fact even poor triggers should work; as this is no P-TTL or anything complicated. I have tried my K20D at "trailing curtain synch" setting now and, all of a sudden, everything seems to work! At this setting I am able to use the trigger at 1/180th sec! Simple as that! No need to ask my question 'elsewhere' :) Bulent --------------------------------------------------------------------- http://www.flickr.com/photos/bc_the_path/ http://photo.net/photodb/user?user_id=2226822 http://www.pentaxphotogallery.com/artists/bulentcelasun 2011/12/1 John Sessoms <[email protected]>: > I use Paul C.
