At Focusbug HQ we’ve been busy working on beta DSP (digital signal processing) solutions for “focus tracking” and “autofocus” functions offered by various lens control manufacturers. Although the Cine RT System was created primarily as a professional reference tool to aid traditional pulling focus methods, we have found that we are able to output data that makes focus tracking viable.

The following test is an example of our current firmware development. We have recently been working with PLC Electonic Solutions* and Heden using their new Ymer-3 due to its impressive ability to handle serial data. It is key that an LCS is able to send the Cine RT distance information as fast as possible to its motors, and Heden achieves this. We will continue to optimize our data processing and will release more examples of the Cine RT working with the Ymer-3 and other LCS systems in the near future. A beta version of our LCS Focus Tracking firmware will be released later this year. Currently, communication with existing LCS systems is one-way only.

In these examples of the Cine RT System working with the Ymer-3 LCS, a Cine RT BUG Transmitter has been hidden on the subject. The footage was shot on a Sony A7R3 in APS-C Mode at a framerate of 29.97 and a shutter speed of 1/500th of a second to minimize the effects of motion blur. In APS-C mode our Zeiss CZ2 70-200 became a 300m and was shot wide open at T2.9. We look forward to providing examples using other lenses, stops, framerates and shutter speeds with both the Cine RT BUG TX and Rangefinder as we beta test our firmware.
