再問一個小問題:小小白IS在30D上暗處對焦精確度和速度如何?
還有動態追焦能力? I know that if your lens is equal or faster than f2.8, the camera body will have more accurate focusing
That\'s probabily another advantage of 小白IS
I mostly shoot my daughter, and she is getting more and more active now.
Actually, instead of getting a 70-200, I am also considering to replace my 17-55 to a 24-70 or a 24-105 for more pratical use on my 20D.
dright, does you 24-70 has 移焦 problem? I\'ve heard this quite often. Otherwise, it\'s a great lens.
24-105 is even more pratical(38-168mm equivalent). Have you use this lens?
