The biggest feature of the Hi‑5 for me is the swappable radio modules – I feel more confident as a Focus Puller and know that I won’t lose connection in those important shots where a re-take isn’t possible. The Hi‑5 & cforce mini RF is a very convenient package: I can use with any camera setup, have playback and camera control and wireless transfer lens files.

Focus Puller/1st AC Bobby Rao

The Hi‑5 has opened new doors when it comes to on-set workflow and efficiency. Smart pre-marked rings cutting down on menu flipping during lens changes; camera control with the swipe of a finger; integrated Focusbug technology to limit how many remote controllers you have to carry. The Hi‑5 is doing it all and more as new features become available! I can’t see myself using a different hand unit.

1st AC Brian Aichlmayr

The Hi‑5 unit has been a game-changer for me. As soon as you pick it up, you can feel the more streamlined design instantly. It hugs your hands better than any handset currently on the market. The fresh menu layout flows more organically than its predecessors, and the addition of a touchscreen means immediate adjustments. The new method to change lens data files is a major improvement – quicker and more intuitive accessibility, plus the new ‘recent’ page means far less waiting time for a fix on sharps after swinging. Less fiddling through menus has made LDA changes instant.

1st AC Anthony Rilocapro

Focus pulling has always been a tough challenge in Hong Kong. We often have to shoot in confined spaces, and ACs can only work from afar or without a line of sight to the camera. Interference is also quite severe here, where wireless devices are widely used. The powerful radio signal of the new Hi‑5 gives me the highest confidence in terms of stability.

1st AC Kei Ching Lui

There is virtually no lag between the Hi‑5 and the motor. Being a little old fashioned, I prefer to be close to the camera, so the hand unit’s responsiveness really is a treat when dealing with fast focus pulls. One of the features I love most is the new lens menu where you can manually set parameters to display the depth of field indicators. I love playing around with the depth of field in terms of where I place the focus, so this feature makes me extremely happy.

1st AC Mohd Abudin Abdullah

Compared to the WCU‑4, the Hi‑5 has no more dropped connections, and the focus knob feels firmer and more comfortable in my hands. The buttons are easier to press, which means that I haven't made any REC mistakes. The touch panel is also quite intuitive and easy to use for any operation.

1st AC Shingo Ito

All I can say - the Hi‑5 is my companion. Hi‑5 is exactly what I’ve been waiting for, for years. I don’t have to change battery every few hours because Hi‑5 works whole day on one battery. Changing premarked rings has never been that easy. ECS Sync app allows me to store all LDA maps in my iPhone and share with my colleagues. New menu and pages are very intuitive. Hi‑5 gives me the opportunity to control cameras easier and faster.

1st AC Andrzej Hijewski (known for “Jiu Jitsu”, “Paul Apostole of Christ”, commercials work, and more)

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.

1st AC Karl Keil (known for “Homeland," "Babylon Berlin," music videos, and more)

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.

1st AC Georg Lanz (known for "Checker Tobi und der unsichtbare Schatz," "Frank Elstner: Just One Last Question," commercials work, and more)

If you get your hands on the Hi‑5 you will not want to go back. It feels like they listened to all the wishes we focus pullers had to create a device which helps us to perform at our best on set.

Hi-5 FAQ

  • 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. 

  • Lens data is generated on the camera side and displayed on the Hi‑5. The data is generated in one of two ways:

    1. From LDS lenses, via the internal lens encoders
    2. From the Lens Data Archive (LDA), via the motor encoders
  • 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.

  • Yes, you can use the cforce mini RF with the Hi‑5 when equipped with the white-coded RF-EMIP Radio Module.

  • 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).

  • 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.

  • 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)

  • It depends on which exchangeable radio module is being used. With the RF-EMIP radio module, the battery lasts up to 15 hours.

  • 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.

  • Manual calibration requires a software update and will be supported at a later point in time.

  • 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:

    1. Hi‑5 (LBUS) to (LBUS) lens motors
    2. Hi‑5 (LBUS) to (LCS) camera or motor controller
  • 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.
