I got mixed results as well, but in think that has more to do with me struggling with the settings.
Compared to my old camera (400D) the 5d3 has lots and lots of options that can be altered to adjust the AF system. Still figuring out how everything works.
I am not up for doing wedding photography yet, but working hard on improving my skills. Practicing on concert photography mostly at the moment.
What I do miss though is the AF point being visible in the VF after focussing, but it depends on the program you are using.
Anyone got some tips for the AF settings? Like whether to use the full 61 AF points, or just go for center with expanding points etc.
Would love to hear what the pro's have to say about this
