General Maintenance

Cleaning the Lens

Check periodically. A small amount of dust or dirt on the lens has minimal effect on image quality. To
avoid the risk of scratching the lens, clean only if absolutely necessary.

Remove Dust

1. Brush most of the dust from the lens with a camel-hair brush or blow dust away with a dust-free
blower.
2. Fold a microfibre cloth smooth and gently wipe remaining dust particles from the lens. Wipe
evenly with the smooth portion of the cloth that has no folds or creases. Do not apply pressure
with your fingers – use the tension in the folded cloth itself to collect dust.
3. If significant dust is still bound to the surface, dampen a clean microfibre cloth with coated optics
cleaning solution (damp, not dripping). Wipe gently until clean.

Remove Fingerprints, Smudges, or Oil

1. Brush away most of the dust with a camel-hair brush and/or blow away using a dust-free blower.
2. Roll a lens tissue around a swab and soak it in coated optics cleaning solution. The tissue should
be damp, but not dripping.
3. Gently wipe the surface using a figure-8 motion. Repeat this motion until the blemish is removed.
