On Sunday my 7D started sending ERR messages. Tried all the usual fixes but after about thirty seconds ERR would appear again. Finally the camera would not power up at all. I called Canon and they sent a shipping label. This is the second time in four months of owning the 7D that is has gone to New Jersey, the first was for erratic focusing. They fixed the focus but now I have this problem. I really like the camera but have reached a point where I'm not sure I can depend on it. How much crap does a person have to absorb before demanding a new camera from Canon?
