I discovered that the NX5U is sensitive to RF Energy and I want to save you the frightening moment I had recently...Twice.
1. I had a wireless video transmitter on my camera to remote monitor what my other camera operator was shooting in a multicam shoot.
It was a cheap one at about 400 mhz. The device was laid on top of the camera. Suddenly, the focus system started moving from zero to infinity and back. I found that the transmitter was laid across the keypad area under where the monitor closes. When I moved the antenna about a foot away, the ghost focusing stopped.
2. Another day, no wireless transmitter. However, I had a second wireless receiver mounted on the rear hot shoe. The first wireless receiver was mounted on the front hotshoe and I use this configuration all the time. The rear wireless receiver, in the 650 mhz range, had its antenna laying across that same keypad which resides on top of the camera. Suddnely, the zoom started moving to full zoom. I could zoom it back but as soon as I let go of the controls it went to full zoom.
I roted the wireless receiver 90 degress so the antenna pointed out to the right of the acamera and the ghost zoom stopped.
Sony Please fix this.
Users, please be carefull.
