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

first, it must've been a large place since I had a hard time trying to do the same with a 1.2/50 lens.  things were too tightly cropped and I wish I had more room.

I agree with the others that the pictures are a bit blurry and not what I would expect from the lens.  was the venue dark?

I would want at least a 1/150 shutter speed, especially if you are shooting hald-held and with moving targets.  with the E-M5, I would go up to ISO 6400 without too much hesitation, and in your case, bumping up the ISO generously probably would have led to a better image than trying to deal with low shutter speeds.  and if you go B&W like in your last two images, an even higher ISO wouldn't be too bad either.
