I thought I'd also share my first wedding shots taken with my XT-1. I am a former Nikon shooter (D90/D700) and recently switched to Fuji.

(Your feedback is appreciated as I am looking at making this a sustainable business)
I'll start with the lenses. The 23mm is the one that stayed on the camera the most (about 75% of the shots) and did a fine job. I also used the 60mm for some macro shots and a few portraits, and the 14mm for some tight-indoors situations and some group shots. All of the lenses had sufficiently good AF speed (including the 60mm).
Compared to my experience with the D700, I found that the XT-1 lagged behind in
- responsiveness (shot-to-shot delay, e.g. after a burst of shots, resulting in a few missed shots)
- AF accuracy (I had fewer keepers, although this may be partly due to me still having to familiarize with the system). I did not find AF speed to be an issue
- battery life (big time. Even with the grip and the extra battery, I missed not having to worry about battery life! I have enough things to pay attention to!)
- Oh I also miss the full frame, but that was not a surprise :-)
On the upper side, I found reduced size/weight to be the feature which made the switchover worth it. The camera is less intimidating for the people, less tiring to use, etc. When I pick up a DSLR now I feel like I'm holding a brick. The vertical grip made it much easier to hold the XT-1 even in landscape mode (not to mention in portrait mode). I have long fingers. This may be less of a problem for folks with smaller hands out there.
The EVF and the tilting back screen are awesome, too.
While I'm at it, I thought I'd also mention I had MUCH better results in post processing with Iridient developer than with LR (especially when it comes to B&W conversion). Really. Much better.
Hope this helps!
