Summary: Very easy to use with a solid mount, and the picture quality is excellent. I've used cheap wide angle converters on other cameras, and they've all come with a cost of image quality. Not this one. It basically lives on my camera now, and is really easy to pop off when I want more telephoto. The best thing I've purchased for the little camera by far.
Summary: This clever wide angle converter using two elements is terrific for its special purpose: giving you an 11mm lens (22 mm, 35mm equivalent) on the 14-46, f/3.5 to 5.6, IIR micro four-thirds lens. It's built for that purpose, almost alone. The pictures are quite reasonably sharp for the cost and design, and I think it will suit my purpose in aurora chasing in Norway this winter.
This wide-angle converter is awesome for non-professional photographers

Summary: This wide-angle converter is awesome for non-professional photographers. The only drawback I see is one must be very careful, when putting it on the lens, not to get some dirt inside. This might be tricky if you are on a windy beach. There is some distortion on the pictures but it is not noticeable from non-professionals. It might be better to use a separate wide-angle lens but the price is much higher.
Summary: Does it's job very well. It's a little unbalanced on an emp2 but it is still comfortable with a wrist strap. For casual shooters on a budget, this is a solid way to squeeze a few more mm out of your kit lens.
Summary: I tried some cheap generic converters, but they were always soft on the edges and not worth the trouble. This one is great though -- noticeably increases the FOV without degrading the image. I may one day get a true wide angle lens, but until then this is a good supplement to the kit lens that fits in a bag nicely. The only thing that confused me at first is that it takes a little more pressure to snap on than the macro converter does.
Summary: This lens performs well - but I had to apply a couple layers of tape to the threads to keep it on. Since figuring out that workaround I have been happy with the pictures. Would be nicer if Olympus comes up with a version that fits the 9-18 wide angle lens.
