Autofocus is pretty fast, even in the dark it will lock on, but you have to look for contrast in the frame, that's the easiest way to get a lock. And even if you can't do that..then you have the amazing Manual Focus. Equipped with focus peaking and split image, focusing manually is an absolute joy. Don't expect the battery to be as good as on your DSLR, the battery of my Nikon D700 can last for days, and up to 2500 frames or more. Fuji says that you will get around 330 frames out of this battery, but you can probably extend that if the camera is not in high performance mode, you don't use the screen as much and you are taking single images, not bursts. I've solved this problem by buying 2 additional third party batteries for 10$ each instead of paying Fuji 50$ for one. Thats true for other accessories as well, as the third party options are most of the times as good as their Fuji counterparts for a 1/4 of the price, check out JJC photo accessories.
Next stop, the camera bag.
