I use the Lenspen for many years. I discovered this cleaning tool when buying a Canon EOS 50E with film there is much of that 10 to 15 years. Since then, I always have one on me when I do an output pictures. A light brush to remove dust and there are marks on the optics, use the cleaning pad by rotation from the center and away gradually to the outside of optics, always rotated. Now I just discovered the mini Lenspen that has nothing to envy its big brother for use on small optical, kind APN Compact. One thing to avoid is to blow yourself on optics during cleaning because the postilions in their heart's content, it is worse than better. I say this because it happened to me LOL.
