Sorry ar....as I am a beginner, so I don't know what details I should tell....ok....I tried 60mm once in Canon Show Room, the environment you know gar la.....after I bought the 100mm , and tried to shoot in my room....the envirnoment is darker then Canon Show room, and I just free to pick some object to shoot....I find the Lens seems move "in" , move "out'..... it could not find the focus on the object....especially the black object ?? any problem in such environment, or could you tell me what I should tell you....and what is the appropriate envirnoment and setting to us ethis len s?

從來在光線偏暗的室內環境下，自動對焦是困難的。
從來對著反差少的物件(例如你的黑色物件)上作自動對焦是困難的。

你試一試大白天出外拍照，看看有沒有這個問題。

請留意支鏡, 最近對焦距離係0.31米, 太近會對唔到焦

Thank you so much.....最近對焦距離係0.31米....and even I move away more to the object...the lens still difficult or evenca't find the focus...I think the problem should be the lightness of the environment and the obeject it self....I will go out in day time to try try sin.....

But I use the Kit Set Lens to take the photo in my room, same environment (dark), the Kit set lens is very easy to focus.... so is it macro need the very bright environment ?

每支鏡的對焦能力都有分別。

影macro會減兩級光圈光量, 係難少少, 如果你用tamron 90mm macro, 仲火熟

Oh I see....then is it 60mm is more easy to get the focus ?? or actually the same ??

Try to get focus by your eyes on a plain wall and you will know how the lenses behave.

Hello 1492,

Sorry I don't know what you means...."try to get the focus by your eyes" ?? by my eyes ?? or by the lens ? What u mean plain wall ? means solid color .... no object on the wall ?
