I need to clean my lens becouse thre is a finger print on it, I dont even know how it got there, maybe my brother,

But whats a good kit to clean the lense and LCD

You should buy a "micro-fiber" cloth for coated lenses. I got one from an optical store. Also I bought eye glasses cleaner/spray. It must say that it is safe for coated lenses and that it's non-abrassive. Blow away any small/loose particles first and then wipe with the micro-fiber" cloth. Sometimes the cloth itself is enough to clean the lens and LCD. Never spray the cleaner directly on the lense. Spray it on the cloth.
