USB Follow Focus Controller

Accessory for Filmmakers & Photographers

As far as we know, this is the first USB Follow Focus controller that will be released in the world. But the best part is that this device can do MUCH more than controlling focus!

As we have told in our previous article, we have been participating in the beta-testing process of a very nice new device compatible with all Canon HDSLR cameras that will be released by the manufacturer very soon.

Today we can unveil some more details of this amazing accessory that will be extremely useful for both filmmakers and photographers.

Please note: we are not the manufacturers nor designers of this device. We have been testing it and giving feedback, reports and suggestions since 2 months ago.


The controller is pretty well made, it feels solid and strong but it’s lightweight at the same time. Enclosure and knob are made of black anodized aluminum, giving it a very nice look.

It has a round shape design, easy to handle and a 1/4″-20 standard mounting hole on the back face, so you can easily mount it on any kind of support.

It obviously works via USB cable connected to the camera, so basically you can remotely control your camera, but with the HUGE advantage that it does not turn off the rear LCD screen! So think about the possibilities…

The controller can work in 3 different modes:

  • Focus Points
  • Settings adjustment
  • Focus Zone selection

As you can see on the picture it has 9 multifunctional buttons, 1 knob, a power switch and a very nice and helpful multicolor LED.

The controller usually comes with white buttons (except the Start/Stop button which is red), but the user can also replace them with other colors.

It’s amazing how well the manufacturer has implemented such a bunch of features in this device with a LED that changes its color to indicate almost all actions, helping the user to exactly know what he/she is doing.

There is a HUGE work behind this device, and a HUGE potential inside it (available to the user!).

Some of the features include:

  • Turn Live View mode On/Off
  • Start/Stop Video recording
  • Take pictures
  • Change/Pull focus using the knob or 2 dedicated buttons (Near/Far smooth focus buttons) even whilst recording video
  • Capability to save 4 focus points (2 “hard stop” points + 2 focus points) and do a Rack Focus by just pressing any of those buttons
  • Toggle Zoom level x1, x5 and x10
  • Change camera settings
  • and much more… (full details will be available after the official release)


The USB Controller is fully compatible with the following cameras:


The manufacturer kindly allowed us to give all readers a COUPON CODE to get $50 discount!

This code will be published after the official release in just few days, so stay tuned!

Using the USB Follow Focus Controller

This very short video (without sound, sorry) is only intended to show some operations that can be done, and some of the controller’s features. Sorry for not being able to provide a HD video this time (see at bottom). Also, since the LED is very bright, in this video it is not easy to see how good it actually is and how much it tells once you learn the controller’s operation.

Basically, on this video we did the following operations:

  • ISO adjustment
  • Turn Live View mode ON (ISO, aperture, shutter speed and exposure compensation can also be changed in LV mode)
  • Check focus of subject “David” using zoom level function, and save focus point #1 for later use
  • Move the focus zone to the subject “chair”, adjust focus using the knob with the help of zoom level and save focus point #2
  • Start recording video
  • Rack focus from focus point #2 to focus point #1 by simply pressing focus point #1
  • Stop recording video
  • Move the focus zone to subject “David” to show that the rack focus was done properly.

Setup: Canon 5D Mark II + Canon EF 24-70 2.8L @50mm

Additional Comments

After testing and using the controller for over 2 months, we can certainly say it is AMAZING. It’s one of those accessories you start to love especially if you are a filmmaker or someone who do macro photography (or do those kind of video/photography shootings that require avoid touching the camera/lens or when it’s hard to access to them).

It’s important to note that a USB Follow Focus doesn’t work exactly as a mechanical Follow Focus, especially due Canon’s USB implementation and since the controller is electronic and not mechanic. Both have their own limitations and advantages.

The user should read the detailed information provided by the manufacturer to understand the way this works, its possibilities, what it can and can’t do. That will be available on the official release.

We will post Full HD video and more details in few days after the official release, so stay tuned!

NON-Official ISO on Canon DSLRs


We have been testing for over a month a very nice new device compatible with all Canon HDSLR cameras that will be released by the manufacturer soon.

During this testing process we discovered a very interesting and unexpected function that is available on some cameras. This option is not available using the camera menu, but only using this device.


Basically what we found is that the user can set some “intermediate” and high ISO settings that are NOT available through the camera’s menu!

The “intermediate” ISO found on the Canon EOS 5D Mark II were: 64, 80, 10000, 16000 and 20000.

We were very excited when we found ISO 64 and 80 available, thinking as another low ISO / low noise shooting option.
