想問下各位師兄既意見。小弟準備入一支 Canon 70-200. 不過就諗唔掂應該入支 f/4 IS 定 f/2.8無IS 好~~~ 真係好難揀~ 價錢又差唔多~ 我主要係用來影室內 event 野多~ 支 f/4 IS 比支 f/2.8 輕差不多一半，係細一級但有 IS. f/2.8 就大一級，即使收細兩級影都唔怕太暗，但就無IS同重一陪。

想問下大家意見，同想知道兩支鏡既質素會唔會相差好遠? 唔該唔該~~~

Canon 70-200 f/2.8 IS 首選~
對於室內, 大光圈及防震一定有用~

一買就買好d, 無謂前前後後浪費$$$~ 小弟就行過呢條路~
早知一早就買70-200 2.8 IS~

但缺點係重~ 但肯定係你任何時候都啱用~

希望幫到你~ ^.^

hkchub,

The problem for 70-200 f2.8 is heavy and expensive but I agreed IS is a very useful function especaily at 200mm. Image quality f4 IS even better than 2.8 but f2.8 is already very good and the difference is not huge.

You better go to the showroom and ask them to mount the 70-200 2.8 on the body model that you currently used to feel the weight.

你睇怕唔怕重, 事關支F4真係輕好多~

F2.8 加 1.4x 重有 F4，加 2X 重有 F5.6。

F4 就分別得返 F5.6 同 F8。

f/4 鏡竟然sharp過 2.8??? 我仲以為貴d會sharp d 添。

多謝各位師兄既意見呀~ 想信我應該會決定要支 f/4，因為好似sharp度同重量都優勝，特別係sharp度。多謝 yung2 提供既網站，對我既決定都幾大影響~ 估唔到原來分別咁大~

我早兩日都去百老匯買左支F4 IS，$8500有免息分期，

真係快靚正，只係重過支100mm Macro些少。
