GH2 Image flaws
Hello, I recently started shooting video with the Voigtlander 25mm on my Lumix GH2. At my last shoot I started to get these large rolling lines through the image. Here is a clip:
Anyone have an explanation for this? I've shot in this environment plenty of times with the kit lens and it's never happened. Thanks in advance for your help. |

Re: GH2 Image flaws
Just that lens causes the interference?

Re: GH2 Image flaws
That is not a flaws, it is the shutter speed not correct under the type of light that you have, change the shutter speed and it will go away.

Re: GH2 Image flaws
It was fluorescent lighting I'm sure. Happened to me and I had no idea what what going on, it freaked me out. I eventually figured it out.
Anyway to minimize this issue in post? |

Re: GH2 Image flaws
No easy way to fix in post. I am curious about the conditions that could create this as it resembles the bane of analog video, radio interference in the wires. If this is the result of 60hz fluorescent, I assume a shutter speed of 1/20th would cause this as the chip scans down.
