如題
請高手指教指教

高手唔敢講，我都仲學緊野。
L既意思係豪華咁解，必要條件係一定要有UD低色散鏡片、非球面鏡片及螢石鏡片之其一，而且都係防塵防水滴。
IS，光學防手震。
如果有任何遺漏或講錯，希望咁多位師兄指正。

ccrsc,

Most of the points for "L" len are correct except NOT ALL "L" lens are dust and moisture seal.

IS is stand for Image stabliser and it comes to 4 generations and the lastest 4th generation can provide upto 4-stop stablisation.

L means "LUXURY"(豪華)，一定有非球面鏡片/螢石鏡片/UD低色散鏡片，AND防塵防水滴,有紅圈識別...
IS---Image stabliser (光學影像穩定系統),第四generation...可以用低4級快門拍攝!有MODE1 AND 2!

[iCatchU]

what's the diff between mode 1 and 2?

[JSmith]

mode 1 係全方向性，即一般用途，例如打雀
mode 2 係for橫向動作，如拍pan鏡，就用此mode
