I'm thinking of the possibility of using the Fujifilm X100s, an APS-C sensored (1.5X) fixed focal length 23mm f/2 compact camera for formals and group shots at weddings. The quality of the image I think is sufficient for a lot of documentary work at close range, and the AF seems accurate and fast, but I'm a little uncertain about the quality for large groups vs. a DSLR such as the D800. The reason I'm thinking of using it is simply that it can flash sync up to 1/1000s or so without issues or power loss (at largest apertures there can be some issues at very fast speeds apparently, but I'd use the lens stopped down to f/4 ... f/8 for many of these images). So it can be used to balance bright daylight with flash using less powerful (and heavy) flash equipment than a DSLR like the D800. David Hobby in particular seems to have taken a liking for this camera and has been blogging about it. I'm wondering if anyone here has experience using it so far for this application?
