The primary reason is price. However, rebate can affect the price comparison significantly. With the current instant rebates in place, the 17-40mm f/4L is only $250.00 less expensive than its 16-35 f/4L IS counterpart. Many will appreciate the 16-35 f/4L IS's benefits for the difference in price. But again, if money is really tight, the 17-40mm Độ phóng to của 100mm f/2.8 cũng ăn đứt Canon 24-70mm f/4 L IS USM.

At f8 things are almost neck and neck, if anything the f4IS lens actually seems to have the edge. F16 and F32 are considerably and equally effected by diffraction at the 70mm length, f32 is totally unusable in my opinion. 135mm – At 135mm the 70-200 f2.8 L IS II performs similarly when wide open at f2.8 as it did at 70mm.
