There should now be a gap between the edge of the Reducer- Corrector and the lock ring (Fig. 3). 4.

To remove fingerprints or smudges from the lens, use photographic-type lens cleaning fluid and lint-free optical lens cleaning tissue. Don’t use household cleaners or eyeglass-type cleaning cloth or wipes, as they often contain undesirable additives like silicone, which don’t work well on precision optics. Place a few drops of fluid on the tissue (not directly on the lens), wipe gently in a circular Gap Figure 3. Gap between the Reducer- Corrector and lock ring. Figure 5.

Do not “polish” or rub hard when cleaning the lens, as this may scratch it. The tissue may leave fibers on the lens, but they can simply be blown off with a blower bulb.
