Hello, can anyone tell me what is a difference between Arri LDS-1 and LDS-2 as i understand now only Alexa LF and Alexa Mini LF has LDS-2 and LDS-2 lenses are only Signature Primes.
But what is a difference in metadata with those LDS-1 and LDS-2?

The biggest difference from a user's perspective is that when you mount a lens with LDS-2 there is no need to rotate each ring for the position readings to work.
Another difference is an increased data rate provided by LDS-2, increasing the accuracy of frame by frame metadata when shooting at higher frame rates.

Do you allow other companies to license LDS usage on their cameras ? Like Sony and RED?
