ARRI ALEXA Mini LF Ready to Shoot V-Mount Set (LPL) - Manual (Page 33)

Lens Mounts and Lens Handling 33
NOTICE
When adjusting the flange focal depth on the
LPL mount make sure to insert the shims in
the correct orientation. Inserting the shims in
the incorrect orientation (flipped) may result in
a short circuit on the LDS print, compromising
LDS functionality (lens detection and lens data).
WARNING!
Condensation! Risk of electric shock and damage!
Humidity may ingress due to misinstalled lens mounts!
When installing a lens mount, always align and attach properly; never apply force.
Hand-tighten all screws crosswise before final tightening.
Always tighten crosswise with the prescribed tool.
WARNING!
High voltage! Risk of electric shock and fire!
Short circuits may entail lethal injury and damage!
Before each lens mount change, always switch off the camera and disconnect all power sources.
Changing the lens mount while the camera is powered may permanently damage the camera and
lens mount.
Protect sensor and electrical system: Always store the camera with a lens mount properly installed
and capped.
Immediately replace each lens mount after removal.
Change lens mounts in a dust-free environment only.
11.5 Lens Data
ARRI Lens Data System (LDS)
ARRI's Lens Data System (LDS) comprises a range of products generating highly accurate lens
metadata for use on set and in post. LDS describes digital lens settings. Lenses with LDS functionality
deliver information about its current settings (focus distance, iris, focal length) to the camera; the
camera interprets these values and transmits the information to its recording module and optionally to
any further accessories connected to the camera such as a Wireless Compact Unit WCU-4 or ARRI
Master Grips. Lens data is displayed in the viewfinder and as overlays on the SDI outputs, and all lens
data will be embedded in the recorded files as well as the SDI stream.
LDS-2 is the next evolution of ARRI’s Lens Data System for ARRI's Electronic Control System and a
new generation of lenses. LDS-2 delivers more accurate and faster lens data. Compared to LDS-1
it eliminates the need for initial calibration through absolute encoders which cuts time on set when
changing lenses. The new system uses a 8.7x faster interface that enables lens manufacturers to send
more data to the camera than before. LDS-2 extends the possibilities of lens data and is being licensed
to other lens and camera manufacturers.
