5D Mark ii Banding (?) Issue

[Jennbeagle02]

Hey everyone... I'm hoping there's someone out there that can help me figure something out.. I have been having issues with my Canon 5D Markii. I have done a ton of troubleshooting and research but it doesn't seem like there's any explanation for the issue I'm having.

If you take a look at the pictures below, you will see white "banding"? At first I thought it was some kind of sun flair, but it doesn't matter the time of day or where the sun is or even what lens I use. The issue is intermittent, and I've even taken it to my local camera store (they had no ideas as to the issue)

The two track pictures were taken at about 4:00 PM .. 5 minutes from each other, same settings, just different sides of the track. Track runs from South to North.

I went back and looked... it is at high shutter speeds that it happens!!! Which is a HUGE problem since I photograph race cars going 100+ MPH!!! UGH

Your shutter is failing, if not broken.  Time to replace the camera or the shutter.

And, which is why your shutter is gone. I'll bet you never had the camera serviced?
