How do you guys clean your lenses when you're out hunting or at the range? I usually carry a microfiber cloth and LensPen but they don't always do the trick. Any tips for cleaning lenses quickly and safely without scratching them?
Same as for my cameras: (1) use lens caps, (2) Zeiss wet disposable cleaning cloth, followed by microfiber, if necessary. After a couple of times, you should replace the microfiber cloths, in particular when used to clean off (gun) oil specles.
