@imLobo 120 and 620 is essentially the same. It's the spool size that's different. So I have to take all the 120 off of its original spool and put it onto a 620 spool so it fits those older cameras. In pitch dark of course 😜
Leupold and other companies make a lens pen. It is a soft retractable brush on one side and a special pad on the other for cleaning the glass. I use one on my expensive camera lenses and telescope. It will save you time taking things apart.
