Sigma Keychain Lens-Cleaning Cloth

Using a dirty lens will add a blemish to a would-be great photo faster than you can say "cheese." Most ordinary cloth can damage sensitive camera optics, so where's your special lens cloth when you need it? If you use a camera regularly, what you should do is carry a cloth all the time. But who's gonna do that? If it was attached to your keychain, you would--making the Lens Cloth Keychain a stroke of pure brilliance.
