Sigma definitely wants to become a permanent fixture in the cine lens market. The chances for this are certainly not bad, since Sigma&s ART series has already proven several times in the field of photography that complex optical designs can be mastered very well. Sigma now proudly points out that its lenses were used in the shooting of "Top Gun: Maverick", which is scheduled to be released in cinemas in 2020.
For the hobbyhorses from the SIGMA CINE "Art-Prime" series, which competes directly with the Zeiss Master Primes due to its high luminous intensity, there is now a new PL mount that supports the /i-Technology communication protocol from Cooke Optics. This protocol allows the lens to transmit metadata such as focusing distance, focal length and aperture to the camera. The lenses are designed for image circles of 43.3mm (with max. 46.3mm illumination) and should be able to support even 8K resolutions on current FF cameras.
The same applies to the previously announced, but now firmly presented at the IBC n "FF-Classic-Prime-Line". In contrast to the Cine ART Prime series, the "classics" are supposed to have the character of older Cine-Primes. According to Sigma, they offer "a unique combination of low contrast and artistic reflexes or ghosting in the picture". The FF Classic Prime-Line offers a constant T value across the entire product line (14mm and 135mm T3.2, all other T2.5 lenses), which is not as small as with the ART primes.
Sigma beriets has shown in a demo video how this can or should work:
The FF-"FF-Classic-Prime-Line" is to be introduced at the end of 2019 at an as yet unknown price. They will only be offered as a set with 10 primes. These lenses will also be offered with the new /i technology.
SIGMA customers who have already purchased a SIGMA PL mount lens will be offered a new service to convert their lenses to /i technology.
And completely without /i-Technology protocol works the likewise announced mount converter from PL to L-Mount named MC-31 against it. Sigma has indicated neither price nor availability for this, however, wants to show on the IBC 2019 already a series model what an early availability lets expect. Of course, this also fits perfectly to the own Sigma fp camera, which has an L-Mount connector:
