This one's for all of you Fujifilm junkies out there. Fuji just released new firmware updates for the X-Pro 1 and X-E1 that upgrade autofocus performance, audio performance on the X-E1, and allows for use of the new 14mm XF lens on both bodies. There's also an update for the 35mm XF lens that improves AF accuracy.
Here's a silly little video from Fuji walking you through the firmware update process if you've never done it before. You can also read about the process here.
