但係唔知邊隻好, 因為見 kenko 同 canon 都係差唔多價錢, 用過既 ching 俾d意見呢?最好仲可以有相睇啦...
同埋 canon 都有兩隻, 12 同 25 呢個數字係咩意思呢？12 會唔會冇咁近呢？因為見佢個價錢好平, 大約 $5xx 就有交易, 好似幾底玩咁, 但唔知質數會唔會差過 25 好多呢？

extension tube只係一條空心管，唔同牌子對成像有分別嗎？

Extension tube can be used on EF-S lens as JSmith C-hing said it is just a hollow tube Kenko also have electronic contact so that you can have AF although it is difficult and metering can still be use.

I have one set Kenko which have three thickness, 12mm 20mm and 36mm you can use any one, any two or all three. If your body has live view it will be useful for extension tube macro and with tripod. It cost me around HK$ 880.

I am using the Kenko one, quite ok and easy to use. but when i am using with 70-200, quite difficult to focus, but i think this is common problem of extension tube.
