Signs of a camera sensor going bad? 2 years 9 months ago #151752

I just got a call from a buddy of mine who has a not to old Canon 7D that he uses A LOT. He estimates the camera has nearly 70,000 photos on it. Any way he was just telling me that some of the images are getting black lines going through them. And was asking me if I knew what this might be. I was guessing but thought his sensor might be going out with that many shots taken with the camera. What do you think?

More than likely he is using flash above sync. But, it could also be a transfer error.

Use a card reader to upload with.

No, he's not using a flash. Apparently these lines are finely spaced apart and going vertical.

Well he needs to do a process of elimination. First he needs to shoot several photos under ideal lighting and see if the lines are consistent. Then he needs to change out his CF/SD card and see if it shows up on the second card. If it does then something is wrong with the camera, if it only shows on one card then he has the answer.

They rate shutters with a "mean time before failure" rating, which is often between 100K and 300K. There is no reason a chip should go bad though.

What has been mentioned above are all possibilities. Corrupt cards, transfer errors, or some sort of glitch in the electronics.

What Joves suggested is the best approach. Keep narrowing the problem down till you find out what is causing it.

eta Ask him if he's done a FORMAT on the card recently.
