I don't know if anyone has had experience of this, but my Canon 5D Mk 1 fitted with 24 - 105 has started to develop about 5 parallel red lines over the top of the picture (on the left in Portrait). You can really see it on darker pictures.

I've changed CF cards twice, upgraded to the latest software, and re-set camera settings, but its still doing it. I will have to send back to Canon - unless anyone knows anything else to try? :bang:

All comments and advice appreciated.
 
is it anything like this banding post 16 if you scroll down.


regards Merc

Looks like sensor problems.

Do you have a sensor Loupe, to get a good look at the sensor surface.

Have you tried to clean the sensor and shoveled the dirt all the way to one end.

Remeber that it's on the opposite side on your sensor as the image is flipped by the lens.
 
All,

As I thought, it'll have to go back to Canon. Thanks to everyone for their comments
 
Did you use a wireless trigger? I've read problems before with wireless triggers on a 5D classic.
 
Strobemonkey, you could be onto something here...done some extensive tests and without being in a studio, no problem. The problem is definitely there with studio lights on. Will try other avenues but looks like this could be a winner.....thanks to all for you offers of advice.
 
OK, thanks to all previous posters for their help - here is a bit of an update. I've done a firmware upgrade, and when used outside there is no problem with the camera at all. But in the studio there are definite issues. I've changed wireless triggers and receivers to see if its a fault with them, but the red wavy lines are there regardless of the wireless kit in use.

So still open to any further advice but looks like its going to have to go to Canon.....
 
It would appear to be caused by your Shutter speed being too fast.

So it's something in the environment in your studio? From your previous post, specifically the studio lights?

You've ruled out the wireless transmitters. Sounds like the lights are emitting some kind of electromagnetic interference.

I'd be looking at them, and particularly their power supply - I'm assuming they are mains powered?

What happens if you shoot in your studio with some other light source and your usual lights disconnected from the mains (preferably removed to another room)?

Some precedent with a Quantum turbo battery - see post #37

I remember many years ago I had an Apple Quadra 800 that kept coming back to the Apple dealer I was working for in tech support because it was constantly crashing. We soak tested it for days and never got it to crash. Sent it back and the client would be on the phone within a few hours saying it was crashing every five minutes. It came back about five times and each time we sent it back saying we could find nothing wrong with it. We had the client come in to the office to see it working and they had to agree that it was OK.

Eventually, I made a site visit (they were a good customer) and lo! it crashed repeatedly in front of my eyes. I was utterly flummoxed.

The studio was in a basement. I popped out into the street for a cigarette and while I was there noticed that next door was an electricity sub-station - right next to where the poorly Mac was situated.

We moved the Mac to the other side of the room and it suddenly it started working fine. :)

Thanks for the suggestions to both, I'll do some more investigating.
