題目450d ket 鏡,is防手震問題~     Post time: 8 月 23 日

小弟買左450d一段日子啦,先發現個鏡頭防手震唔知係唔係出左問題

有時用1/60s或更慢快門影相~開同閂左個is都係出現相片模糊ge問題~

我當然知道自己有手震(手唔係好定),不過,我最想知ge就係~

點先知我個防手震功能係正常運作緊??

有冇d咩測試做到~唔該哂咁多位ching~

A. check IS
1. set T mode & iso 100
2. focus on a newspaper
3. shoot use indoor in continuous mode for 3 photos @1/10 @ 55mm with IS on
4.repeat with 3 photos @1/10 @55mm with IS off
5. repeat with @1/3 @18mm with IS on, then with IS off

if the IS is ok, then there should be difference between IS on & IS off

B. check AF
1. use central focus point
2. focus on the central line of scale45.jpg (download from
http://photo.net/learn/focustest/ )
3. if AF ok, the central line is the sharpest
