謝謝連拍捕捉的建議，就是70-200mm 需要在空曠些的地方，另外

I totally agree with you in that a minute difference in a small detail can instantly boost the quality of a picture. Usually when I look at pictures from continous shooting, I can only find one great one and that is if I am lucky. Most pictures have lots of room for improvement. I will try to get better by practicing. :-) Thanks again for the tips.
