2 fixation screws for focus lock
- the focus ring still shows some clearance after locking. This due to the mechanical design of the
lens. Anyway, the focus is fixed.

As default, the lens is adjusted for 50" SXGA systems. In case of an 80" SXGA+ system, the
screws[6] have to be loosened: use a hexagon key size 1.5mm to remove the paint from the
screws, loosen the screws, and turn the lens until its adjusted to 80" (84") SXGA+ (red
scale), see picture below. Then tighten the screws again.
