Section 2: Service Guidelines
2.3.2 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.
Dust
:
1. Brush most of the dust away with a camel-hair brush and/or blow dust away with a dust-free blower.
2. Fold a microfibre cloth smooth and gently wipe 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 cleaner
solution (damp, not dripping). Wipe gently until clean.
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 cleaner solution. Tissue should be damp, but
not dripping.
3. Gently wipe the surface with a figure-8 motion. Repeat this motion until the blemish is removed.
