Now it’s here “Steadicam focus slider”

It is elementary in all film and video photography is to set the focus exactly where you want it.
With the Steadicam Focus Slider you can do so on their own, without touching the optics.

We work with Steadicam know how difficult it is to not be able to set itself smoothly focus where you want
have it.

Many people ask how I arrange this when I’m working with Steadicam.

During my 20 years as a Steadicam operator, figured out how to solve the problem. A couple of years
then I took out a prototype that I called the Steadicam Focus Slider, which I worked with during
many years in TV production. There were several operators who saw it and asked what I had got hold of
it and if I could build several for sale. I can now present the results.

Can be purchased from Dick Ying, Sweden

Hello Dick, I'm curious to know how your focus slider drives the lens...do you use some sort of MDR/motor combo? Internal focus servo?
Also, how do you operate zoom?

Best Regards,
Bryan

You can switch focus spool diret to optics, or via a servo motor via the six pin HRS (HIROSE) connector.

Do you use them new digital Canon lenses, so you need to use a
cable adapter, we use as the analog input on the optics.

Zoom mounted on the side of gimbol handle.

Send two photos so you can see how I have mounted on my Ultra 2

Sorry for my bad English, but I think that you get a good picture of how it works.

So trying to wrap my head around what you've done, it seems to me that you've replaced a rotary potentiometer with a linear potentiometer and that's it

Myself have had a rotary potentiometer,
but I did not know what I was on the scale.
With a Slide Potentiometers you see what you are with the focus much easier. And you can write focus marks on the slider.

hope you understand what I mean.

You can connect the diret to optics, or via a servo motor via the six pin HRS (HIROSE) contact.
