Thanks for the tip, it seems like a fine lens. I heard that it maybe did not perform so well under poor lighting conditions however. Do you have any experience with it? What about the speed of focus compared to 18-55mm?
No, I do not have experience with it, but I have 18-55 and it is just not long enough. Particularly you will notice it with your sport shooting. I found 28-105 even more useful - sure it is not wide enough, but seems to be OK. 18-125 obviously not the best performer, but quite OK. If would be very difficult to have "one-lens-for-all" with top quality pix. Hey, this is why we are buying DSLR - to have fun with lens changing :-)
