Stuck Lenses
Due to the introduction of physically larger lenses, over-tightening the lens, rotating
the lens too quickly in the lens mount or the presence of dirt in the threads of the
lens or mount may cause the lens to become stuck in the lens mount.
In order to prevent incidents of this nature, a fibre washer is now fitted to all new
lenses before shipping. Users with lenses shipped prior to the introduction of this
washer are advised to request them when placing their next order. Digital Projection
also recommends the following installation procedure for all lenses.
1. Check the fibre washer is in place and the lens is in good condition.
2. Check the lens and lens mount screw threads are free from dirt and metal
shavings.
3. Ensure the motorised lens mount is in the disengaged position.
If fitting a
POWER gv
lens, ensure the lens adapter is fitted.
4. Fully support the weight of the lens while offering it up to the lens mount.
5. Carefully guide the rear of the lens into the guide ring at the rear of the mount.
6. Continuing to support the weight of the lens (especially at the front) apply a
slight rearward pressure and rotate counter-clockwise until a click is heard.
7. Slowly rotate the lens clockwise until it seats against the lens mount (do not
over-tighten).
8. Turn the lens mount lever clockwise to engage.
