副廠廣角大光圈變焦鏡疑問

wfcwen

最近在找廣角鏡,CANON 17-40L覺得光圈有點小
除了CANON 16-35 F2.8L 以外,副廠鏡可裝在 FF上的的廣角大光圈變焦鏡有那些
最好是有圖可參考啦,感激不盡

Sigma 15-30mm is better than the new 12-24mm, it is a bit soft.
See http://www.pbase.com/kazfujieda/lenstest&page=all, this guy from Japan compare a lot of Sigma lens.

You can also see this http://www.16-9.net/ultrawides/, which is 12-24mm vs 15-30mm vs 17-40mm vs Zeiss.
