I'm thinking of buying a wide angle lens for my 300D.

A candidate is Sigma 12-24mm. If I put a 82mm uv filter on it, will I get dark corners? More seriously, without any filter, are there still dark corners? How about on film cameras?

I love Canon 17-40mm f4, but it's $1k more, and it's not as wide as Sigma.

等下啦，Canon EFS 10~22mm 嚟緊啦！(6k幾wor!)

Waaa! >$6k. Is it worthy? I'd rather go for Canon 17-40mm.

17~40mm俾唔到咁wide給你，因為要X大1.6倍(CCD SIZE的問題)，所以只得27.2mm~62mm。但係10~22mm就唔同，經換算後就有16~35.2mm，影風景時你就知幾好用！
