Summary: Works well with the 14mm prime lens which i received with my Lumix GX-1. Have used this lens for both pictures and video with great results. An affordable wide angle option for those who can't afford a more expensive lens such as the Panasonic 7-14mm.
Very nice way to obtain a light and compact ultra-wide

Summary: I have other lenses that cover this field of view, but they are expensive, large and heavy. Carrying the Wide Conversion Lens along with the 14mm f/2.5 provides a way to have a very wide field of view available in a small package. The lens performance is surprisingly good for a wide converter setup, with only a bit of easily correctible barrel distortion (when it matters) and sharp corners/edges once stopped down to f/4.5-5.6.
Summary: This conversion lens comes with 37 or 46mm attachment rings and as others have written you can use with the power zoom or the 14 prime. I have actually left it attached to the prime and I bag it that way. I have a better 20mm prime 1.7 (a wonderful lens) so if I need the light, I'm not going to be using the power zoom or the 14. Hope that makes sense. I would love to get the 12-35 2.8 which is a sweet lens....but a grand for a lens just ain't gonna happen right now.
Summary: liked cheaper than a dedicated lens good performance (use it more than i expected I would) dis-liked can't put a filter on it to protect the glass don't like the screw ring, and twist click design
Summary: If you have the 14-42 PZ X lens this is a must buy. It adds a significant amount more to your shots and it does not distort the picture in any way. I have almost 1000 shots with this attachment and it is great for indoors photography.
Summary: I got this to complement the 14mm f2.5 wide lens. I also have the powerzoom but I guess I never use the converter with that. It does exactly what it says, makes the 14mm into an 11mm. I was pleased with the results of photographing aurora last fall, because it allowed me to go wider without reducing the aperture (it actually increases the f-number, if I understand how these things work). I don't care for the build quality.
Summary: Although I would have much rather preferred the 7-14 zoom lens, I couldn't see parting with the money for the amount of times I would use it. This adds a slightly wider angle for a relatively inexpensive cost. I use this on my 14mm lens and it works as advertised.
