Hi everybody, my name is Franc Anderson. I'd like to talk to you about cleaning your SLR
camera lens. Now the lens just like the camera body of course, should be kept in your camera
bag well away from dust and dirt. With lenses and bodies always need regular cleaning. So
first of all we take off the exterior dust and dirt with a stiff brush like this. Brush
the outside of the body, all the crevices and then when you've got the outside of the
body clean, you can perhaps give it a wipe with a special lint free cloth.
And then take off the lens cap. The lens cap should be on at all times when the camera
and the lens are not in use. This keeps dust out of the body. We need to clean the cap.
Dust and dirt collects everywhere there's a crevice. Now let's turn our attention to
the lens. All lenses should have a filter on at all times, a UV filter or a skylight
filter, this won't affect the color of your images. Remove the filter and clean it again,
initially with a stiff brush, both sides and now you have to turn your attention to this
optically flat surface. Take good care of it. It will degrade your images if you don't.
Now to clean the filter, the most convenient way is to use a lens cleaning tissue. Do not
use like a paper handkerchief. Just breath on the surface of the filter like that and
gently with a circular motion clean both sides of the filter surface. If the filter's surface
is really dirty, you can clean it with a lens tissue and some commercially produced lens
cleaning fluid. Moisten the tissue with the fluid. And again with a circular motion, clean
the surface of the filter. Use another dry tissue to finish the job off.
The same can be done with the surface of the lens itself but be very, very careful. The
surface of a lens is very soft and very delicate so you can brush it first with a brush like
this. You can buy this at any camera store and very, very gently using the tissue, you
can clean the surface of your lens. This should be largely unnecessary because this filter
should be in place at all times. Finally, pay attention to the back surface of the lens.
This is usually recessed. Turn the lens up like this and try to brush all the dust from
the surface of the lens and from the cavity. Replace the cap. And now you've got a nice,
sparkling, clean lens. Put it back in the bag right.
