I use canon 7D, which lens is better?
Canon EF 17-40mm f/4.0L USM or
Canon EF-S 15-85mm f/3.5-5.6 IS USM
Thanks a lots

i prefer 15-85,
better range,
with IS

For FF, 17-40 is value for money.
For APS-C, 15-85 worths every penny. 淨係15mm=24mm 個廣角已經值回票價.

其實你常影咩野多? 景? 人?
如果景嘅話就17 40 啦，因風景常收光圈，F/4 一定夠用，遲D你上FF 時又用到，又有紅圈，肥花賣緊$5XXX 炸，抵:)
