I 'd go for EF 17-40mm F4L

15-85 ，看過D比較，好似有點唔值，同支17-85差唔多炸……
咁不如二手17-85 or 直上 17-40 有價值D

I' ve 15-85 i like it wide as 24mm on my 500D, & the pic is BRAVO ^ ^

15-85 夠唔夠SHARP,色水又點呢?

[wow9]

you use 7D which is a cropped frame anyway, so neither 15-85 nor 17-40 will be wide enough...
id personally go for 17-40 as better PQ and constant aperture at F4, as well as the internal zooming within the barrow so less dusting problem.
