This was a new one. I was covering aftermath of a high-speed 18-wheeler chase. A trooper asked me to move because I was in the "scene". I decided my best shot was going to be from out in the field next to the freeway, so I pushed through the ankle-high weeds until I got a decent angle.
As I was shooting, I noticed a strange vibration on my hand when I was touching the zoom rocker and iris control. It wasn't constant, but it was frequent. There was no visible problem in the viewfinder, and just looking at the lens I couldn't SEE a problem.
My first assumption was that it was the zoom servo acting up, so I threw it into manual. It kept doing it. Then I unplugged the lens cable altogether. It kept doing it. Then, just to be sure, I turned of the camera. To my surprise, it STILL did it. I had never felt this before and was stumped how I was going to explain this one to the engineers.
I powered the camera back up and rejoined my reporter and other media by the police tape. As we got soundbites and traffic shots, I noticed the vibration was gone, completely. Now I was really stumped, but when we were waiting for the police PIO to come give us the official word, I figured it out.
Strung directly over the piece of field I had used for my shots were multiple high-voltage power lines. I apparently was in a strong elecro-magnetic field. I never saw any glitches in the video resulting from it.
Has anyone else experienced this or heard of it? I'd like to know what it was doing to me and my camera. I'm just glad I'm done having kids!
