Say Hi to Hi-5!
Making your life easier on set
Get to know the system
The first thing I thought when I held it in my hands was actually, 'The Eagle has landed.' It’s an absolutely 'from you for you' product, because I can see an extremely large amount of input from assistants in the industry implemented. The Hi-5 feels great and I'm quite sure it will become the new gold standard for focus pullers worldwide.

It's one thing to keep a shot in focus; it's another to support your DP's artistic vision. While juggling these tasks, I have to fully rely on a tool that enables me to control every aspect of camera work on set. The Hi-5, while allowing me to do all of this, is a reliable companion that fades into the background when I need to concentrate, and offers surprisingly versatile ways to tackle all challenges that set life throws at me.

How does lens data get into the Hi-5?
A lens table is transmitted to the Hi-5 from the camera device where the lens data is generated. ALEXA Mini and Mini LF cameras, the Universal Motor Controller UMC-4, the cforce mini RF lens motor, and the Radio Interface Adapter RIA-1 all support wireless lens file transfer. Classic ALEXA cameras including the Plus module load lens files from an SD card.
Where is the lens data generated?
Lens data is generated on the camera side and displayed on the Hi-5. The data is generated in one of two ways:
- From LDS lenses, via the internal lens encoders
- From the Lens Data Archive (LDA), via the motor encoders
What is the Lens Data Archive and how does it work?
The Lens Data Archive (LDA) is an archive that contains lens tables. Those lens tables set the raw motor encoder values in correlation to the actual lens scales. Once you choose the right lens table from the Lens Data Archive and calibrate your lens motors, you get the same type of lens data as an LDS lens would deliver. You can create your own lens tables for any given lens with the Hi-5 and save them internally, externally to a USB-C flash drive, or in an iOS device with the ECS Sync App. Lens tables can then be transferred wirelessly from Hi-5 to the ALEXA Mini/Mini LF, the Radio Interface Adapter RIA-1, the Universal Motor Controller UMC-4, or the cforce mini RF lens motor.
Does the Hi-5 work with the cforce mini RF?
Yes, you can use the cforce mini RF with the Hi-5 when equipped with the white-coded RF-EMIP Radio Module.
Do you have a Smart Focus Ring for each lens?
There are many different lenses on the market and we do not have an individual pre-marked ring for all of them. We do have 10 pre-marked rings with metric scale and 10 with imperial scale. These rings can be mapped to any given lens by using the Lens Data Archive (LDA).
How do I choose the right Smart Focus Ring?
There are various ways to make good use of pre-marked rings. You can choose the ring marked with a close focus or minimum object distance (MOD) that is nearest to – but less than – the MOD of your lens. For example, if your lens MOD is 16”, you would choose the 14” focus ring. Or you simply select the ring with the focus scale spread that best matches your scene.
Can I use WCU-4 pre-marked rings on the Hi-5?
The following WCU-4 pre-marked rings are compatible with the Hi-5:
Metric: 0.20 m, 0.25 m, 0.35 m, 0.50 m, 1.00 m
Imperial: 3’6, 20” (= 1’8)
How long does the Li-Ion Battery Back LBP-3500 last with the Hi-5?
It depends on which exchangeable radio module is being used. With the RF-EMIP radio module, the battery lasts up to 15 hours.
Is the OVR override function of the Operator Control Unit OCU-1 also available with the Hi-5?
Yes, it is. The Hi-5 indicates the override mode, which is triggered by the Operator Control Unit OCU-1 or the Master Grips. The override function enables operators to return focus, iris, or zoom control to the OCU-1/Master Grips at the touch of a button.
Can I manually calibrate a lens with the Hi-5?
Manual calibration requires a software update and will be supported at a later point in time.
Can I use the Hi-5 hardwired to a camera?
Yes, you can use the Hi-5 hardwired connected to the camera or motor controller via the LBUS (4p) interface on the Hi-5. The following cable connection is supported:
- Hi-5 (LBUS) to (LBUS) lens motors
- Hi-5 (LBUS) to (LCS) camera or motor controller
Can I use the Hi-5 with cameras other than ALEXA cameras?
Yes, you can use the Hi-5 with any camera, by using the Radio Interface Adapter RIA-1 with one of our new radio modules (RF-EMIP, RF-2400, RF-900) connected to the camera via the CAM (7p) interface on the RIA-1.
The following cables are available:
- K2.0015758 Cable CAM (7p) – RED CTRL/D-Tap (0.6 m/2’)
- K2.0018814 Cable CAM (7p) – Sony Venice/F55 CTRL/D-Tap (0.6 m/2’)
- K2.0015757 Cable CAM (7p) – LANC/D-Tap (0.6 m/2’)
If the Cable CAM (7p) is too short, you can use following cable as a CAM cable extension:
- K2.0023832 Cable CAM (7p, f) – CAM (7p, m) (0.3 m/1’)
Alternatively, you can use the Universal Motor Controller UMC-4, the cforce mini RF, or the Mini Motor Controllers AMC-1, SMC-1 and EMC-1 with the RF-EMIP attached to the Hi-5.
