I have pretty much kept my autofocus lock in the middle setting. Yesterday I changed it to Long for capturing bikes in motion after reading that it works great for BIF.
I believe this has improved a bit. From off to long what are some scenarios to use them for. For example for baseball, soccer what would you set it to.
While the manual gives explanations to me they are generic and I can understand them better with actual photos like in BIF thread
For the following photo I my settings AF/ON AF-C 9 point normally I pick single point but I was trying different things.
