The lens par excellence! Easy, fast focus, bright image sharp - super. Anyone else just zooms used at some point again to to use your feet. The only problem is that you can no longer remove the thing from the camera, because once you've seen through the 50's if one is not really doing to the dim vision of the world through a 3.5-5.6er Zoom. Strong buy recommendation - it is simply one of the best lenses on the market.
