EF-S 17-85mm f4-5.6 IS USM

17-85 has IS bor. u no need large aperture for wide angle. anyway 2.8 is not consider large aperture when compare compare to 50 1.4 or 1.8. they are not expensive.

[alexchon]

yes , sigma 17-70 only use f2.8 in 17mm ,and how about the price between both lens

[alexchon]

so actually for 30d user , which lens is better ?
is the kit lens is really fit ?

[Vistaresort]

f2.8 連70mm都有就有用, 始終唔係人像鏡,
標準zoom, IS比大"一級光圈" 好用好多

Considering optical quality, 17-85 sucks.

[rlpang]

how about 17-55 f2.8 IS USM?
i think the quality is better than 17-85, and it has big aperture also.

17-55 f2.8 IS USM too expensive
17-85 IS & Tamron A16 more reasonable
