I must say, I'm very impressed with my new telecon ad wicon lenses. They use the 52 mm adapter--not the one that comes with the Kodak camera. That is metal, feels very firm and never sticks. The telecon is made in China by a company I never heard of. The wicon is made by Kenko (maker of all kinds of gagets). They are fairly cheap but I really enjoy exploring a new dimension of picture taking. The quality is acceptable to me.
