各位師兄師姊

小弟相買幾支鏡但不夠經驗想大家給我一的意見

1 . Sigma 17-70 F2.8 – 4.5 Macro 與 Canon 17-85 (30D Kit鏡) 與 Canon17-40

2 . Sigma 10-20與 12-24與 Canon 10-22

3 . Canon 50m 1.4 可否作人像鏡用

小弟以上鏡用在 Canon 30D

請多多賜教

kit 鏡就差D,但靚既原廠應該係首選,如果能力負擔得起的話.

如果負擔唔起,Sigma and Tamron 都是不錯之選擇.

我本人係喜愛用Sigma 鏡,因為價錢同質素都成正比,有D仲會起值的感覺.

買Sigma 鏡最好用EX鏡質素有保証.

Sigma 150 mm APO EX DG Macro 2.8




Sigma 70-200mm APO EX DG Macro 2.8



Sigma 8mm F3.5 Ex Circular Fisheye



Sigma 10-20 mm F4-5.6 Ex Dc Hsm

Ringomov兄

首先多谢你的寶貴意見,不過小弟想問你Sigma 8mm F3.5 Ex Circular Fisheye所影的想是否用D80影8mm又是否x1.5=12mm
又Sigma 10-20 mm F4-5.6 Ex Dc Hsm所影的用多小mm可否告知小弟因你支鏡10-20mm如可以請告知未x1.5的數

[ringomov]

我係用D80 影既當然要x1.5焦距

10x1.5=15mm

支8mm魚眼都是x1.5,所以見唔哂個圓形.

用Sigma 10-20mm 有時唔好去到哂,要視付環景需要而定,
唔係全張相就變哂形.
