I have also shot weddings with a X-T1 and a X-E1...I mostly use the 27mm, 35mm and 56mm ( I keep the 55-200 in my bag but I rarely use it)
I now shoot weddings 100% with fuji since the beginning of 2015. Before that, I was using Canon.
The great thing that I love with the 56mm and X-T1 is that I can shoot at F/1.2 and the shot will be in focus.
Indoor, during the reception, I like to use my Rovelight flash ( from Adorama...so you can google it if you don't know what it is) and I bounce it on the ceiling ( since the rovelight is so powerful, it does not matter how high it is)....if the walls and ceiling are wooden or dark, then I bounce thru a white umbrella.
Sometimes, during the dancing of the guests I pop the Fuji flash (EF 42) on the X-T1 and use a really slow shutter speed...
Yes, indoor for dancing the AF might be slower than a DSLR, but ALL cameras have their own limitations and you learn to work around them
ps : I also shot an Indian wedding with my X-T1....and we all know that Indian weddings are NOT slow paced!!!!
