candid shots weddind with75 mm f 1.8, all taken handheld/ last shot was cropped. i was a bit far.

Dantep, you've captured some nice moments here which is really important in wedding photography. But as has been said, your settings are completely inappropriate and I would advise going back to basics and refreshing your knowledge. Don't be afraid to crank the ISO on the OMD, it's great for that kind of thing, I'll happily shoot at 5000 ISO and the noise is not objectionable at all.
