Video Stabilizer + Follow Focus + Wireless HDMI Video

It seem like every time I post a video stabilizer review, I often receive the same question - 'How can you adjust focus?'. Typically i'll just answer this question by replying with a text comment, but i'm sure it's still not very clear. Hopefully this article can help visualize a few ways focus can be achieved when a camera is balanced on a stabilizer, thrown on a video crane, or other device where adjusting the lens would be cumbersome or impossible.

One option to adjust focus (without physically touching the lens) can be by use of an electronic follow focus system. In the video below, Vimeo member Nicholas D shares how he's setup his camera on a SteddiePod Stabilizer with a Cinematics USB follow focus [Thanks Nick]. The USB systems will be limited, as they will only work with certain cameras (mostly Canon) and only with compatible auto focus lenses - not manual lenses.

An alternative could be to use dedicated Wired or Wireless electronic follow focus systems attached to the outside lens gear. The benefits to these systems is that they can be used with pretty much any lens that supports manual focus. The throw can be remapped for shorter or longer focus movements at the dial, and higher end systems allow to you store focus points. The full wireless systems are helpful when you need another person to manage focus so that the camera operator can move about freely.

If you plan to work with a Wireless Follow Focus, Camera Motion Research has announced the new Radian Pro kits that will send a Wireless HD Video stream via HDMI to a remote monitor. There are ways to achieve this through a DIY solution, but the Radian Pro claims to use a more commercial version transmitter / receiver that can transmit through a broader range of channels for longer distance, low latency, and clearer image. The Radian Pro is available in both a Unicast or MultiCast version (multiple video streams).

For myself, I may not use a WFF for every project, but I do use Wireless Video when operating on longer cranes/jibs or even just to share a feed for others to view (so they aren't hanging over your shoulder). Add a remote Pan/Tilt head to this combination, and you'll be able to man a camera from a distance away while focusing and zooming. Great when you have to leave a camera somewhere you can't be seen like on stage, or perhaps even at a church during a wedding, or in the middle of a racetrack.

Sorry for the lack of great examples, but hopefully this article is somewhat helpful and gives you ideas of what you can do with such tools. Remember that these are not limited to just these types of Stabilizers (a.k.a Steadicam). These are the same tools that can be used on those amazing Brushless Motor Camera Gimbal Stabilizers everyone has been recently obsessed about.

    @Ben Prater - This Sigma lens specifically does not change it's dimensions when zooming in or out like other lenses. Everything happens internally in the lens, so it doesn't affect the balance. Canon's new 24-70mm F/2.8 is the same way.

  2. Heya Daf. We tested the Manfrotto USB focus controller pretty extensively in the rental department of the store that I work at. The performance seems to have a lot to do with the lens. Some lenses changed focus very fluidly, others were very choppy. It probably depends on the focussing motor. Try another lens and see if it helps.

    Hey Em. On the Senna wireless system, is there any kind of latency / delay when you pull focus wirelessly? Or is completely real time which would obviously be awesome.

    So roughly how much is everything there, wireless follow focus, monitor, hood case, batteries, etc...? I guess everything but the camera and lens? Around $6000?

  5. Talking about this at work - videographer says he has a USB follow focus - not sure this one.
    Is problematic though
    - at first setting - the motor is quite slow
    - at the second setting - rather than being smooth and fast - it steps - so you see a series of small sudden changes.

    Hey Emm
    I'm really curious about the wireless HDMI. Is it possible to record onto a ninja two via wireless?

    @Greg Greenhaw - Might be an interesting test. As I've heard there are commercial versions of these transmitters and consumer versions which will have less range.

    Though overpriced, I always thought the Steddiepod seemed pretty interesting. What ruins it for me is the company owner. Terrible social media skills. He's always lurking around faking comments and angrily responding to all criticisms. He'd probably get more business if he let people come to their own conclusions about the product.

  9. Hey Emm great video man.Last year I was on a Jean-Claude Van Damme set (Welcome to The Jungle) here in Puerto Rico (pictures on my web site) and they were filming with two Red cams and a remote follow focus system. It was the first time I seen this in action and it works great. Thanks for sharing and showing us a lower priced setup we can actually afford.

  10. Very cool Emm! By the way, is that your place where you were shooting? If so, that is nice and inspirational in and of itself.

    Be blessed my friend.
