I've used it on many lenses over the years, with varying success, and haven't lost one yet (we're not talking about *bathing* the thing in lighter fluid). I am increasingly persuaded, though, that this simply does not work with the modern, synthetic damping gels and lubricants that manufacturers now use. I don't know this, but, what the hell, I'll speculate anyway. My CV 28/1.9 is useable, but next to the Konica 21-35 and the Leitz glass, it's become a real pain to focus quickly and accurately. It was stiff when I bought it, but I thought it reasonable to allow a breaking in period; after two years of nearly constant use, it's gotten, if anything, worse.
