Six months ago, I bought the Olympus 40-150er for 151.- Euro and am excited about the sharpness of the lens. Such sharp images are I never succeeded. Very good also the edge sharpness. That was always angry with my previous Canon and Nikon zooms, blurred image edges! Not quite as good, but also a bargain, by the way is the new Standardzomm 14-42 II from Panasonic. Toll, with two very inexpensive and lightweight lenses to my G3, I am now happy.
