Master Grip Control of ENG Lenses on Alexa 35
Posted: Tue Dec 03, 2024 5:47 am
I currently have an Alexa 35 with LPL LBUS Mount and LPL-PL Adapter. My Canon ENG Zooms (17-120, 25-250) get full data and power pass through from the mount.
I'm wondering what the easiest way would be to control the zoom axis with a Master Grip. I currently have a MRR-1 which I was hoping would control zoom over a single LBUS cable but the grip says "No Control"
Based on my research it looks like I might need an LCUBE CUB-2 to control the zoom. What does the wiring look like in this case?
LPL Mount - LBUS Cable - CUB-2 - LBUS Cable - MRR-1? And the lens plugged into the CUB-2 Hirose port? What is the 2nd Hirose port on the CUB-2 for? Do I also need a Hirose PL Mount?
Preston makes a cable that goes directly from the Digital Microforce to the Canon 20-pin Hirose on the bottom of the lens. No additional cables or boxes required. I understand that the MRR-1 works on a different protocol than the lens does, but I'm hoping there is a simpler way to control the existing lens motors without a mess of cables on the camera.
