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?
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.
