2.4 Lens
The lens is composed of different parts, the interesting parts are:
A* Aperture ring
To set the lens aperture (or opening).
The higher the number is, darker the image will be, but the sharpness
between near and far objects will be improved.
The smaller the number is, lighter the image will be, but the
sharpness between near and far object will decrease.
On new lenses, this ring do not exists any more; so the lens remote
control is mandatory.
B Zoom ring To choose the focal length of the lens. This ring does not exist on
fixed focal lenses.
C Focus ring To adjust the sharpness (or focus). Must be set in relation to the
distance between the lens and the middle of the track; the final setting
must be done when viewing the image on the computer (OSV-STAR
software in setting mode).
D Hood
Removable mechanical part. Must be mounted to protect the lens
from sun and rain.
E* Aperture lock
In the locked position, the aperture cannot be adjusted manually.
* For camera with lens remote control , set the aperture ring [A] to the highest number and
move the aperture lock [E] to stop the aperture ring turning.
For camera without lens remote control , verify the aperture ring [A] can be manually turned;
if not, move the aperture lock [E].
To be able to control the focus by software, the lens must be on the AF mode; this is done
differently according to the lens (small switch or focus ring sliding).
F
If the focus is manually changed on the lens in AF mode, the mode must be set on M and then
again on AF in order to allow software focus remote control.
