Problems with camera/lens...help please!
 

I noticed my camera or lens has been acting just recently.
The last time the camera was used was for videos by a friend.

I was just looking into practicing my liveview focusing for the 85L on the 5dmk2 when I noticed that the live view screen part had like weird lines going across the screen, so i sorta played around with some settings such as the grids and lines and it went away.

But then i tried to take some pics right after just for fun and noticed my pictures are coming out all dis-colored.

here's an example

the next 3 were shot consecutively...

all were on AWB as i normally do not adjust that until i get into my comp and do it from the raw file.

Before this, i've never had a problem shooting at stuff from my kitchen in the same spot.

any advice or answers?
much appreciated.

edit: i also forgot to mention i tried to take pics with and without the uv filter on after and it was the same conclusion.

is your light source flourescent lighting ? will you get that banding away from a flourescent light?

will that also happen with any lens?

google search yields results explaining its due to florescent light source.
try shooting at a shutter speed slower than 1/60 to see if the banding still occurs.
