5.1 LENS
5.1.1 Lens Elements
The front and rear surface of your lenses should be inspected regu-
larly 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 cleaning 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 fashion, starting
from the center and working towards the outter 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 should 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 mount 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 directly 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 surface 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
Lens Cleaning Tips
Avoid handling lens tissues 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 scratchs on
lens surfaces are caused by poor
cleaning methods.
