I bought VG10 three months ago. Recently I have noticed grain in the picture that look like vertical lines. It is visible in the darker areas of the picture.
It is not usual grain that you can see in the video. It looks like someone just wiped it's sensor from top to the bottom and leave lines. Strange. I didn't touch/wipe sensor before it. I tried to clean senzor after I noticed that but it didn't help. Does anyone know what could cause this?
