I just bought this lens and brought it with me to hong kong. One lens is enough, didnt even use my flash much. I think its the best of the many lens i had so far ( didnt have any L lens yet). I had 24,28,40,50,100,18-55,18-50/2.8,24-60/2.8,24-85/3.5-4.5,28-105/3.5-4.5,55-200 before, now only left this n the kit lens.
