I use back-button AF. Great for birds (bump-focus), useful for focus recompose. Only downside is if you hand your camera to someone else, but green-square mode cancels back-button AF.Me too!
Me three! I have so many blurry photos of myself that I actually set C3 to Shutter AF+AE, f/8, Auto-ISO, and other settings to make the shots as idiot proof as possible
