Thanks to my knowledge gained in practice, I found this product to be absolutely useless. The lens only produces a distorted, blurry picture with noticeable chromatic aberration.The only pro is that its easy to attach, but that's about it. The cons of this lens far outweigh any benefits it may have. Save your money and buy something better..
Pros
Increases the angle of view of your Panasonic camera for wider shots
I bought a universal lens and a panasonic lens for my Lumix LX5. You can definitely tell the difference. The Panasonic lens produces much sharper images. I sent the generic back. For some things you pay good money for quality, shoes and glasses.
