radio use

I read on this forum board that using radios around cameras can mess with the auto focus? is this true?
also what are the dynamics to this? Is it only if you are in front of the camera or the radio is right near the camera?
What if the radio is strapped to your waist?

Can anyone give some insight and some low price alternatives?

My initial reaction is "hogwash". But then, i'm not an electronics guru. Of course, you can always try it and see what happens.

the guys says GMRS radios interfer with steadyshot?

Can anyone verify this?

What is a GMRS radio?

gmrs or grms are the a longer distance radio that runs approx 5-8 mi.

The poster did not say the GMRS was the problem but that gmrs radios which can use regular frequencies (short range) as well.
So perhaps this style of radio is just problematic with steady shot?

I assume no one knows anything on this.

or maybe no one saw the post...
Some phones will mess with the audio on various cams, there is quite a lengthy thread, including audio samples, of phones interfering with various gear due to frequency, proximity, both.
I've not heard of the focus being affected, but can imagine that IR in the right location close enough *might* hit the remote sensor or something obtuse like that.

Probably related - I can confirm firsthand that a ringing cellphone near a VX-2000 cam does something, though I'm not sure what just yet. Over the weekend I was shooting some handheld detail shots of a facility when my phone rang in my pocket, and the internals of the cam started..."moving", as if I was zooming in or out. The picture didn't change though, and I'm not sure if the typical cellphone ba-deep ba-deep BUZZZZZZZZZZ tone made it onto tape or not. Audio wasn't critical for what I was shooting at that time so I wasn't monitoring it.

I can confirm that using walkie talkies (the Motorola kind like you find at Costco - FMRS style) around a Sony VX2100 with SteadyShot on will physically move the lens up and to one side. We were trying to use the radios as a cheap camera intercom and every time we keyed the radio, the picture would slide up and over. If you turn off the Steady Shot, there's no problem. I believe when we were doing it, we had the radios on our waists, using boom headsets. We never tested to see how far away we could move them.

It is my understanding that some RF can affect OIS. When that happens you are best turning the stabilization off. EIS like on the HVR-A1 is not affected. Is this by chance what you are talking about?
