I believe that ClearSight is superior, if nothing else, for the fact that it contains no harsh chemicals and it leaves no residue. ROR is ammonia based, Zeiss is made of alcohol and water. ClearSight is surfactant based. Future batches of Clearsight will contain an antifog agent, requested by motorcyclists, and for those who must have it, there will be a stronger formula. I think we will call it Formula One or maybe Ferrari, but I think the royalties for the latter would be too high. As for microfiber cloths, I like two brands. Dust-Off and ClearSight. Dust-Off has the feel of silk, while ClearSight feels like soft suede. Both are lintless and do a great job of cleaning. I do not advocate cleaning a dirty lens with a dry cloth, it would be too easy to scratch it. Nor should a cleaner be sprayed directly onto a photographic lens. It might seep down to lower element. I will make an exeption for a very dirty and encrusted lens in order to emulsify the surface dust. But then, a lens should not be allowed to become so dirty. Cinematographers check the optics frequently during filming to eliminate dust before it become a problem. Joe Codispoti http://www.thegrid.net/joecodi/clearsight.html
