5.1 LENS
5.1.1 Lens Elements
The front and rear surfaces of your lenses should be ins-
pected regularly and always kept clean of dust particles, smudges,
fingerprints, etc. First, blow off any large particles of debris using an
air syringe. Lens elements should then be cleaned using lens clea-
ning fluid with lens tissue. Apply a few drops of cleaning fluid to a
fresh lens tissue or directly to the lens. Wipe the lens in a circular fa-
shion, starting from the center and working towards the outer edge.
Finish with a fresh dry tissue. If some streaking remains, repeat the
procedure until the surface is sufficiently clean.
5.1.2 Lens Exterior
The exterior of your lenses such be cleaned of dirt and adhesives as
necessary. Use a multi-purpose cleaner or degreaser such as De-Solv-
It applied with a Q-tip, lens tissue or cotton cloth.
5.1.3 Mounting Surface
Always inspect and keep the surfaces of your lens mounts clean
using alcohol or a multi-purpose cleaner with a Q-tip. Remember,
any debris found on the surface which contacts the lens seat can di-
rectly affect the back focus of your lens. Make sure the Q-tip does
not leave any cotton fibers behind.
5.2 BODY
5.2.1 Exterior
Keep the external body surfaces clean using a cotton cloth with alco-
hol or a multi-purpose cleaner. Use a utility brush with soft bristles
to clean dirt from tight crevices.
5.2.2 Mounting Surfaces
Like the lens mount, extra care should be taken to keep the lens

CLEANING
Lens Cleaning Tips
Avoid handling lens tissue on
the surfaces which will contact
the lens. Oil from your hands
transferred to the lens surface
will make an easy cleaning job
tough. Furthermore, never
clean a lens element without
the aid of cleaning fluid. A
good number of scratches on
lens surfaces are caused by
poor cleaning methods.
