如果用AFS17-55 2.8係咪好過份呢？成像又係点;如果真係用咗佢吟影人像又駛吾駛買多支50MM 1.8呢？

I am using the Sigma 18-50 F2.8 Marco, well fine, I like it!

如果用AFS17-55 2.8係咪好過份呢？ ----> 用三寶都唔過份, 您話用AFS17-55 2.8過唔過份吖. 雖然三寶係for FF機, 但一樣可用於DX機, 同時將來升級都唔洗再重新買鏡 ^_^

成像又係点 ---> 不用懷疑 ^_^

Hi B &H,

I know the AFS17-55 2.8 should be DX lens not FX lens.
We can use this lens on FX DSLR but DX mode only.
That mean we can't 100% work fine of FX DSLR performance.

Sigma 18-50 macro HSM 這隻的
優勢:
近拍、廣角、恆定光圈
缺點:
重、耀光明顯(打太陽必出綠色光影)
如果,沒有需要拍遠距的東西(荷花...總不能下水拍吧),倒是一個好選擇!!

即係話如果現在用afs17-55 2.8dx ; 到第時上FF机可以用DX MODLE用番支鏡都得？^.^

[B and H]

即係話如果現在用afs17-55 2.8dx ; 到第時上FF机可以用DX MODLE用番支鏡都得？^.^ ------> 100% correct. But 12M down to only 6M (D700) and 24M down to around 12M (D3x).
