The two lenses are in a very different class, but the 18-180 is very good at f/7.1 and f/8. The 12-60, as with most of the high-line Zuikos, is excellent wide open and at any focal length. In good light the 18-180 can hold its' own very well. -- Oly
This is really "in your face". A great point of view with superb sharpness and color. Is there much difference in sharpness between your 18-180 and the 12-60? How do you like each lens. I know these are very different lenses, but I am curious, Thanks.
