- the focus ring still shows some clearance after locking. This due to the mechanical design of the
lens. Anyway, the focus is fixed.
The projection lens allows to zoom and to focus the picture. The adjusted settings can be locked by means of
fixation screws.
It is recommended to lock the lens only after the entire adjustment procedure has been
done.
After locking the focus adjustment ring and the zoom adjustment ring it might be
necessary to correct again x, y shift of the picture.
Even if locked, the focus adjustment ring can be slightly turned. Do not worry! The focus
is locked anyway!
