Macro鏡最近對焦距離比較近,可以把物件影得較大.zoom鏡到一定距離會對唔到焦的.
Macro鏡光學質素通常比zoom鏡好.中央及邊緣解像度較一致

Canon has a manual focus EF-mount MPE 65mm F2.8 macro lens capable of 1x to 5x magnification.

Canon支1x to 5x影花芯會適合啲.因為佢最細放大率係1:1,朵花大小小都影唔晒,而且支鏡要七千幾.我建議你買Tamron 90 mm f2.8 macro較適合,焦距唔長唔短.價錢二千尾.

hmm. i am a newbie.. what do you mean by 1:1?

[Philippe]

1:1的意思係真實物件有多大,它的影像在感光完件上就有多大,例如感光完件是24 x 16mm,那麼一件24mm長的物件在1:1放大率時剛可填滿相片的長度.但用1:7.7的放大率的話就需要185mm大的物件才可以, 24mm長的物件只能佔相片長度的1/7.7.
