Years ago Mike Eastman made the case in Hunting High Country Mule Deer for buying the best optics you can afford and it made sense. You can’t hunt what you can’t see! Most of us are very protective of the high end glass that we saved, sacrificed and then spent the money on. It would be a shame to not be able to use high end glass because of damage caused while cleaning. Press play see the optics cleaning kit from Zeiss that can clean any optic without damaging the lens!
