For DSLRs unusable.

I have the Raynox bought by the focal length of my Canon kit lens to expand HD 6600 Pro. As I have already used by my bridge camera Panasonic Lumix DMC FZ7 is a converter from Raynox and was very pleased with the image quality, I thought it can not hurt in the kit lens safely. But this idea has turned out to be bad mistakes that Abbildungsqualtät the HD-6600 is so bad that the images can wrden only deleted. Very strong distortion at the side edges. In addition, still you need an intermediate ring is not included. The picture is also not full at 18mm is always a black ring to see. I can not help but say to a DSLR on the general performance of the HD 6600, the converter no place therefore for all DSLR owners stay away !!!
