A57: refocus issue in continue shooting mode.
I'm thinking of upgrade from A55 to A57 for the better EVF, longer battery life, no overheating and a margin of picture quality. However, when I tested one A57 in Best Buy, I found it won't refocus when I used continue shooting, while A55 does well. I did notice that if you set shooting mode to sport then A57 can continue refocus. It's really disappointed since I use continue shooting a lot to capture my kids' moving. I'm not sure if there is one option to switch the continue refocus on/off. Please let me know if you have a solution. Thanks.
