6 mm CS-mount lens
A low-cost 6 mm lens is available for the High Quality
Camera. This lens is suitable for basic photography.
It can also be used for macro photography because it
can focus objects at very short distances.
Fitting the lens to the camera
The lens is a CS-mount device, so it has a short
back focus and does not need the C-CS adapter
that comes with the High Quality Camera.
Rotate the lens clockwise all the way into the
back focus adjustment ring.
Back focus adjustment ring
and lock screw
The back focus adjustment ring should be
screwed in fully for the shortest possible
back-focal length. Use the back focus lock
screw to make sure it does not move out
of this position when adjusting the aperture
or focus.
Aperture
To adjust the aperture, hold the camera with the lens
facing away from you. Turn the middle ring while
holding the outer ring, furthest from the camera, steady.
Turn clockwise to close the aperture and reduce image
brightness. Turn anti-clockwise to open the aperture.
Once you are happy with the light level, tighten the
screw on the side of the lens to lock the aperture.
Focus
To adjust focus, hold the camera with the lens facing
away from you. Hold the outer two rings of the lens;
this is easier if the aperture is locked as described
above. Turn the camera and the inner ring
anti-clockwise relative to the two outer rings to focus
on a nearby object. Turn them clockwise to focus on a
distant object. You may find you need to adjust the
aperture again after this.
