Already rented the holiday of a fellow here at home confirmed the proper function. Disoriented by uninformed buyer / reviews, I asked only times when Hama Support for, because of the ever resurfaced criticism of blackening. This explained to me just like the few skilled person here at Amazon that this chemical is exactly that makes the perfect cleaning effect. And only on the lens !!!! And that's what makes the Pen.Mein on the FZ 150 and built by Leica lens without any problems, without residue, clean streak-free and safe. The pen is otherwise intended neither for display nor any other area !!
No lens cloth and the like has been able to achieve similar results. Conclusion: Especially on the journey, dusty slopes of Pen is the solution to the problem of lens contamination. This is my first review here, and because I was annoyed about the many wildly wrong / amateur judgments based on ignorance. Jochen Fischer Zell
