15.2.2 Lens Adapter PL Mount LA-PL-2 (with LDS)
The lens mount of the ALEXA Studio supports the ARRI Lens Data
System. The LDS lens must be mounted in the 12 o'clock or 3 o'clock
position to enable the LDS functions. Take great care not to harm any
elements of the LDS contacts on either lens or camera when attaching
or deattaching a lens or lens port cover.
Besides the LDS feature, the same rules as with the LA-PL-1 (on page
60) apply.
