急! 400D用邊支廣角鏡好?

師兄, 可買
Canon EF 17-40mm f/4.0 L USM $5200
Canon EF-S 17-85mm f/4.0-5.6 IS USM $4200(二手$2800~$3100)
這兩鏡會比18-55mm f/3.5-5.6好! 幫朋友影結婚相, 會比較可靠.

個人覺得買17-85mm IS (二手)幾好!
實用焦距, 有IS, 曰常生活相質素,OK!

參考資料:
我有用的廣角鏡Tokina AT-X 12-24mm f/4.0, EF-S 17-85mm f/4.0-5.6 IS.
我有用400D,30D.

本人才疏學淺,只想分享一下.師兄的鏡頭室外影問題不大.EF 50mm f/1.8 影半身人像是不錯的.70-300mm,70這焦距影大頭像也正.18-55mm影團體相也沒有問題.如果在室內用18-55mm 無外閃, 老實講相片成像及銳利會差小小.推高iso, 落腳架慢快門! 影人(人像相). 落腳架慢快門, 師兄諗清楚有無用! 推高iso雜訊會多!不如問朋友借枝外閃用, 室外室內也有用的! 諗諗吧!

師兄, 不如買 Sigma 10-20mm F4-5.6 EX DC HSM

如果無 budget, 400D 支 kit len (18-55mm f/3.5-5.6)都算係 ok....
佢都已經好夠 wide...
但我一直都覺得佢影相有o的曝光不足, 所以, 你可以影果陣, 俾多o的光入去...

Why don't you buy the kit lens 18-55mm, is not bad, compare with my 12-24mm sigma ($42xx). So, I think the kit lens is good enough.
By the way, the photo does not look nice if you use 12mm ( Too wide ) for the group photo. ( Only sharp in the middle , otherwise you have to use f/8).

Of course, the canon 17-40mm is very good. But it cost quite a lot.
:P
