I hope I dont get stoned for saying this on APUG but honestly the best camera for a wedding is a dSLR *LOL* A wedding is a non repeatable event. When I take pictures I want to make sure I can preview the shots.
If i have to use 35mm, I'd use something with a fast autofocus and automatic functions. I usually shoot in Aperature Priority. The last thing I want to do is juggle the guests, and fiddle with the camera.
Manual is fine for artsy shots where you have all the time in the world to get your settings right. But in a high pressure event like wedding photography, you just wanna concentrate on getting it done fast.
