i have both 17-40 and 17-55,the pq almost same,f just mean PQ,i think 17-40 not better 17-55 too much..maybe just better 5-10%(sharpness),但17-40的4光圈絕對可用,甚致可以同17-55收到4一較高低!另一樣要取捨的就是17-40是內變焦,我用了半年亦無加filter到而家一點塵都無,相反17-55是伸缩,我新買完用了一個月已經有明顯的塵在鏡內,但論spec 2.8 + IS 你唔係聞相人必定夠用,最好配7D,hope can help u~enjoy~

15-85我不推介,不是恆定光圈,成像也不及以上兩支,且價錢同17-40差唔多

17-40 o係aps-c 係比17-55 仲差... ff + 17-40 即刻靚哂...
我唔建議因為唔知幾時上ff 而犧牲41-55 焦段... 就算上ff 你都會買24-70/24-105. 17-40未必o岩用開standard range o既人(當然你話到時當wide 鏡用都可以, 但係只多17-23又要換鏡, 變形超勁).
apsc 機上 17-55 f2.8邊位都ok sharp, 17-40 f4 邊位係散. 唔信自己上showroom試o下, (記住試要用d 物件大概同一平面試).
15-85 冇用過唔知... =p
