1000d剛入左支sigma 18-200 dc os有dd問題想問問ching...
如何試防震 ?!
在viewfinder開os有少少浮, 但係唔係會有少少震同有少少聲...(但係一d都feel唔到有震同聲) 只有普通對焦聲.
有咩好方法可以試到個防震...
因為慢快門,開防震好像冇用,200mm快快門開or關os都一樣!?

同有冇咩方法可試有冇走焦?!

take more samples (say 10 each) and compare the best and worst...

Not every time your hand will shake and have the same amplitude, this is by chance...

手持zoom 到最遠200mm...
開IS: 快門set 1/125 影o下... 然後1/60... 1/30...
關IS: 快門set 1/125 影o下... 然後1/60... 1/30...
放大相片.... 對比開IS關IS o既100% crop...
其實你zoom 得遠... 半按快門時... 應該o係觀景器見到明顯變化...
