I'd go with the 28-75 2.8 out of all that's mentioned, (in fact, that's what I plan to grab, myself, for that purpose, among others. At least till there's real pay involved.) A *little* wider would be nice, like a 24-something, but I favor the longer end somewhat, and using a true wide angle like a 16 would be on digital for group portraits is truly a measure of last resort for me... sometimes you just don't have the space or a group is just too large to interact with at the working distance a not-too-wide would require. (This interaction is important.)

Sticking this wide angle capability on a standard zoom means you have to watch out for *distortion,* as well, and when setting up for group shots, you have time for a lens change, anyway, so breaking up the jobs among a couple lenses is a pretty reasonable way to go.

Depends somewhat on your style, though.

Once it can be afforded, the two-bodies matter isn't to be overlooked. There's no second chances at a wedding if one goes down, anyway.
