Compared to the Olympus 14-42mm zoom convinced this prime lens optically in any way: the center a marginally better sharpness can be determined at f3.5, but the image edges falling out visibly softer. At maximum aperture, this difference is even more pronounced and the benefits and limits significantly. The image edges remain significantly softer than the above Zoom Even with f4-11.
Positive are the very small size and processing, but it was not worth the price to me. With the brilliant performance of the Panasonic 20mm F1.7 can not keep this Panasonic lens.
