If you use a tripod, you don't need an IS lens.

>>如動態如雀烏..賽車等又有何分別ar.........
For birds and racing cars, you may want a longer lens

>>如果用d標準鏡如EF 28-135mm f3.5-5.6 IS USM影人像同EF 70-200mmF2.8L USm相比邊支靚D ar.
For 28-69mm portrait, the 28-135 should be better. For 70-200mm portrait, the 70-200 should be better.

>>甘...EF 70-200mmF2.8L USM 影人像OK 嗎?
It is YOU to define your acceptable quality.

>>價格和質數來衡量你地會選擇EF 70-200mmF2.8L USM 定係EF70-200mm f2.8 IS usm??
If you "need" to hold the lens at slow shutter speed, the IS lens is worth the cost.
