With the introduction of the LDE-1 and the SUP 2 for the WCU-4, LDS is available from any lens on any camera regardless if they have LDS capabilities. With the correct selection of accessories depending on the equipment available, now any set-up can benefit from Lens Data, be it on-set or for post.
The Wireless Compact Unit WCU-4 is a lightweight, ergonomic hand unit offering up to 3-axis lens control. The Software Update Packet (SUP) 2.0 for the WCU-4 makes lens programming easier than ever before. Through lens programming, lens tables can be generated for any lens, from vintage anamorphics to modern PL mount zooms, allowing lens data to be collected from them via the Electronic Control System. Lens scales can now be programmed in less than a minute, using the large LCD screen of the WCU-4, with no additional equipment besides the Universal Motor Controller UMC-4 (or an ALEXA Plus or Studio camera) and lens motors. The resulting lens file is stored on an SD card, which can be taken out and reused elsewhere.
The new Lens Data Encoder LDE-1 extends the functionality of the Electronic Control System. Incorporating an encoder that delivers data indicating the position of the lens ring to which it is attached, the LDE-1 can be used in parallel with a manual follow focus unit or a third-party wireless lens control system. It allows lens data to be generated in situations when an ALEXA Plus or Studio (or a UMC-4) is being used without an ARRI lens motor or an LDS lens.
