I was using the camera in automatic focus mode with the half press of the shutter button auto focusing and setting exposure, however this was sometimes slow and not fully under my control with me endinhg up with out of focus and incorrect exposure shots. So now I have the AF point set to the smallest size so I can select to focus on an eye if needed and with camera set in MF mode I point at subject press the AFL button to focus on an exact point and if needed the AEL to lock exposure, which as the spot is small can allow quick and fine adjustment. These are then locked so its easily to recmpose or take further photos in the same light etc very quickly.

I’ve read articles about that technique over the years but I’ve never been able to see any advantage 
over merely using the shutter release.  Although I mentioned, in response to Jim’s query, that the focus 
ring can be turned while in AF to refine focus, you have to have a MF focus aid visible to be accurate with the 
focus.  Since you don’t have a focus aid available (in my quick test yesterday with an X-Pro1) it looked 
too difficult to me to use any manual focus refinement – while AF was available, at least.

So what’s the point, old chap? ;-)
