Camera: Panasonic Lumix GH3Lens: Lumix 20mm 1.7fISO: 1600Settings Manual 1.7f - 1/50This was a test video that I put together using the Panasonic Lumix GH3. As you can see, the low light performance is truly quite amazing. I am seeing horizontal lines that I am not sure what they are being caused by, any thoughts?
