請各影友指點，教路。謝謝！！

問Sigma 17-35 及Canon16-35L/17-40L用於10D有如何表見？
Sigma的變形、黑角及畫質如何？

謝謝！！

17-40L 比較穩陣 !!! 而且價錢可以接受 !!!
D-SLR 大光圈真係好少機會用得著 ~~~~~ 推高 ISO 好過用大光圈 !!!
所以 F/4 已經好夠用了 !!!

its not an objective opinion, as i have never compared it with other combo.

my colleague has exactly the captioned body and lens, and i have found the AF speed is VERY slow, even compared to my collectable EOS RT + non-USM prime lense.
