各級數有又什麼分別?
那麼17-55 IS有幾多級防震?
Thanks ching

CANON最舊的is防震係兩級防震....17-55 IS係三級防震！！
e+近期新出的鏡頭多數係四級防震...但我記得之前有出過極少數鏡頭達到五級防震的...但好似係D賣幾萬元的遠攝定焦白鏡！！

五級防震????? 哪支遠攝定焦白鏡?

200 F2 L so called 5 steps IS..... that means stable even 1/7 s

even you bought it, you won't carry it with you all the time unless photography is your job

Ching, how to calculate 1/7 s for a given 5 steps IS?

冇記錯應該係.
在200mm 原本安全快門是1/200s, 3級即是, 用200除以3, 大概係(1/67.77)1/60s, 那4級便是1/50s, 一般廠商都會講話最大防震達4級, 唔一定係4級, 而隨焦段唔同、環境唔同都會有分別
