I bought also the XLC100 flash which is synchronising with the Rollei35 at any shutter speech. But how do you know than you get a good exposure. Or set it for example at 1/60 and f4 for 100 ASA film for indoor scenes.
I've just found and joined this forum which is brilliant. Like BBonte I'm based in Belgium (Brussels in my case).
I acquired a Rollei 35S a few months ago and have been knocked out by the quality of the Sonnar lens which easily equals those of some of my larger lens cameras. This little camera travels with me everywhere now (at the expense of my trusty Minox GS-E!).
