Hi

So I have this Canon 7D in mint (exterior) condition. Just exposed about 11000 pics with it since I bought it in September 2010. But now it leaves a very strange effect (see pic). Please note that this effect appears on the screen when watching in "live mode" as well.

I suppose I'll have to leave the camera to the local wizard or something, unless anyone here knows a way to fix this?


Cheers.

Looks like common CF card failure. Try a new CF card and see if same results. I had a sandisk card do this and they replaced free of charge (lifetime warranty!).

To me it looks like a corrupt image. Blame the card.

Sorry but no. The CF is ok, and the result is the same with other CF's as well. This effect even appears when watching in "live mode".

Cheers

Good thing it's still under warranty. Time to send it back to the mothership.

Figures, some sort of STD for cameras I suppose, might have gotten it from one of those Nikons.

I'm guessing that you might have bent one of the CF pins. It's as if an entire data stream is missing. Might take a peek in the CF card slot with card removed with a flashlight and see if any pins are bent.

Another option may be a circuit board failure. The data failure is too regular.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

To me, it looks like an addressing problem. Somewhere between the sensor and the processor. Basically canon will replace a circuit board. I'd be curious to see a raw image at the pixel level to see how many pixels are between each black line. Probably a multiple of 8 but just a guess..

True, 8 pixles it is.

I doubt it's the problem in this case, because you mention the same effect appears on the LCD in Live View...

Do you regularly format the memory cards in the camera (and not in your computer)? If you haven't formatted recently, you might try that.

Another thing that probably doesn't apply in this case is how you download the images. Most of the problems I've had over the years (very few, actually) have been due to poor card reader connectivity.

Before you send the camera off, you might try doing a "reboot" to see if that helps.

That means turning off the camera, removing all the batteries (including the silver memory batt), turn the camera on and press the shutter release button once. It won't fire, but this drains any remaining power in the camera and forces it to reboot. Turn it off, put the batteries back in, turn it back on and check the time/date in the menu... You should need to reset it, if you got a proper reboot. You also might need to reset other menu/custom function settings.

You also might check the firmware and update or reinstall it.

Actually I suspect the camera will need to go in for service.... But the above items don't cost anything and are easy to try, before shipping it off.

On the bright side, the camera is still under warranty since it was bought in Sept. last year.
