ARRI ALEXA Mini LF Ready to Shoot V-Mount Set (LPL) - Manual (Page 29)

Lens Mounts and Lens Handling 29
PL-to-LPL Adapter
The PL-to-LPL adapter offers backwards compatibility with all PL
mount lenses, be they Super 35 or full frame. The adapter attach-
es securely to the LPL lens mount without tools, allowing crews to
rapidly switch between PL and LPL lenses on set. The PL-to-LPL
Adapter can be mounted either so that the LDS contacts are in the
12:00 position for ARRI lenses, or so that the LDS contacts are in
the 3:00 position for Cooke lenses. In both positions the adapter
supports LDS-1 and Cooke /i.
The three most common uses of Super 35 PL lenses on the ALEXA Mini LF are:
1 Using an image expander.
2 Cropping the Super 35 area in post.
3 Using the large illumination circle of Ultra Primes, Master Primes or Ultra Wide Zoom (UWZ).
Some anamorphic lenses have their lens data connectors in the 3:00 position. In this case, use a 1.5
mm hex key to reposition the orientation pin of the PL to LPL adapter so that the lens can be mounted
correctly.
11.2 Changing a Lens
LPL Mount, PL-to-LPL Adapter and PL Mount Lenses
Lens change on the LPL mount, the PL mount as well as the PL-to-LPL Adapter works the same way.
An LDS lens must be mounted with the LDS contacts in the 12:00 position to enable the LDS functions.
Take care not to damage the LDS contacts on the lens and the camera when mounting or unmounting
a lens or lens port cover. Any LDS-2 mount and any LDS-2 lens always have the contacts in the 12:00
position. The description below shows the ALEXA Mini LF with an LPL mount attached. When no lens
is attached to the camera, use the lens port cap to prevent dust from entering the lens cavity.
Removing a Lens or the Lens Mount Cap
1. Turn the bayonet ring (1) anticlockwise
until it stops.
2. Remove the lens port cap.
