Hi there,

there has been lots of discussion about cost effective solutions for wireless remote focus pulling. Redrock's planning to release a wireless focus device, and i think Cinevate is developing a remote too:

...and recently we ourselves have released the Foveas Remote Follow Focus and a wireless monitor:

What do you think about these new options? Will they be useful in your opinion for steadi-newbies?

Yes, it seems that quite a few companies are going to be coming out with cheaper remote follow focus solutions by NAB... The red rock looks promessing on paper. I took a look at yours, and found two drawback: first it doesn't have any focus marking ring??? Furthermore you seem to use geardear hardware to hold the motor in place which in my short experience with their product (matte box) is a mistake for everyday use, it's very cheap plastic and a no-no for porfessional use.

Hi Fabrice,

thanks very much for your feedback, yes it seems that on the paper Redrock's should be a great product. I myself maybe would have waited thir product if i would know its release 3 or 4 months ago... :D

As for the drawbacks, i'll try to explain our point. Of course we can be wrong... Please have in mind that we originally designed this system not to be sold, but as a home made alternative for us to work, only later we decided to make it commercially available.

We chose Geardear foam material because we found it a high resistant and veeeery low density material, that makes the rig much lighter than if we would have chosen other materials. We've made tests and it seems very resistant and all parts are very precisely machined. One of the fears we had was if it would be strong enough to hold the servo on position when operating (the torque is quite high) and we found that the knob that controls the position and the material performed fine in this aspect.

And about the marking, well, maybe that's another concept that we had in mind when we designed it... the transmitter has the ability to store up to three positions that you can recall anytime during operation, so instead marking the ring, i believe it's possible just to store positions and recall them later electronically...

Here is a video of how you store positions:


And a limited range of motion between 2 stops can be programmed electronically too, we thought instead of the marking ring again.


But i'm thinking... it should't be difficult to add later a marking ring as a free upgrade if this is not enough...

Anyway, we hope to have soon some units available for unbiased and impartial review that may clarify better these points. Thanks again for you comments.

I like the presets ability, that's a nice plus. I also like the limiter. You are right the focus marking ring should be easy enought to add. It definatly looks nice and compact.

Can't wait to give it a try. Will you have a booth at NAB?
