Love it. Shot a wedding last Saturday in a 4H building and as soon as the processional started and the ring bearer started down the aisle someone was playing with the light switch and turn off all the lights. Almost total darkness, the only light was coming from the windows and my camera/flash was all set for bounce. I shot anyway and ended up with a host of underexposed and a few blurry raw files. They tried to turn the lights back on but it was the kind that are in stadiums and take 15 or 20 mins to warm back up and come on, by that time the ceremony was over. There are a lot that are not recoverable of the ceremony. It is straight on flash for me from now on.
