各位，我用100-400L @400mm 1/320s 開左IS 打雀時都好似震震地
過左1/500s 就無問題，是否正常呢？ (無用腳)

唔正常就假!

防手震係有好過冇既function，但不少拍友奉為神明！

IS係有用`不過唔係萬能,正如安全快門係一個指標,係指通常情況下而已,放係勁手震既朋友度,就算係慢安全快門2倍既時間都可能震,但係有人可以唔開IS都做到1/10都唔震,所以唔出奇

正常!!!!

I can hold wide angle lens without IS 1/10s without significant shake in 100% view, but just couldn't make it stable for 100-400L @400mm 1/320s 開左IS....... Shame
