I'm starting to get very frustrated with the quality of the AF of my gear. I'm currently shooting an a77 and 70-400, and the af tracking is so poor that sometimes I wonder if it does anything at all. It feels like whenever I do get a shot in focus, it's more luck than anything. I've been considering switching systems to canikon for presumably better af tracking performance, but I wanted to make sure that the grass is indeed greener on the other side.
Could you please tell me what percentage of shots like these would come out in perfectly sharp on your system? I know AF is very much system dependent, so please let me know what setup you have.
PS: In case you're wondering, the shutter is set to focus priority, so my camera seems to think that the bird is in focus. (The first case is actually fairly typical of any bird that's big enough in the frame to be worth keeping)
PPS: No the focusing system is not malfunctioning. Static shots come out just fine.
