While this article is focused on the advancements in ARRI lighting technology, one can draw parallels from ARRI’s camera and Professional Camera Accessories (PCA) line to understand the design philosophy and evolution of the greater lighting ecosystem. No other brand has such tight integration between camera, lens, and mechanical or electronic accessories. There are plenty of examples to draw from, but innovations like incorporated wireless focus motor receivers and wireless video transmission in the ALEXA SXT-W, the interconnectivity of the entire LBUS range of motors and focus tools, and wireless range extension for various families of products with the ERM-2400 all showcase ARRI’s unified design philosophy.
