I haven't seen Keitha weigh in here, but she shot an "all prime" wedding last year with her K100D and the results were outstanding. Of course, all of her work is outstanding in my opinion.
Here's a link to her
Flickr stream but she seems to have taken down the set from that wedding. You can find a few in her Portfolio set, though.
Oh, and WesleyWong, that's a great shot! You'll do well with this photography thing, me thinks.
