The 12-60 I bought in the kit with the Olympus E3. It replaced my 11-22 and 14-54er. The image and build quality, I feel excellent. The 12-60 listed in 12-14er area slightly more than the other two. However, I can live well. I use it at E3, E330, E510 and the Panasonic L1. The autofocus finds its target on all my cameras quickly and accurately. Since I have the 12-60 are the other lenses unfortunately in the closet. Who wants to buy a 11-22 now should consider whether it is not the 12-60er are equal preference.
