LensPen

Anyone use one of these? I picked up a set of three and was surprised the cleaning end left black marks on my hand. It seems to have some substance they call CarbonClean for cleaning...not sure what it is or how safe it is.

I've been using it since 2013. The black substance is in the Lid. You're supposed to hold it with the lid pointing up and then turn the lid a little to transfer new black stuff to the pad. It doesn't seem to leave any residue on the lens. I clean the lens with the retractable brush, first.

I haven't noticed any ill effects, though I admit that I'm not using it all that much. I bought it for my digital equipment before I did any film and had any analog equipment. The coating of the digi lenses is state of the art, obviously. I guess I'm simply anot using it often enough to see if it would leave cleaning marks on older lenses.

My sister in law works at the HQ of Hama, the company that came up with it.

I have one but only use it on my filters, I don't trust it on my precious lenses, you only need a speck of dust on the applicator to scratch hell out of your lenses.

I've had good results. But I clean my lenses infrequently.
