Is anyone else having problems with their EOS 40D? Mine - bought new at a high street retailer last November - developed several faults by July 08 and was returned to Canon under warranty. The faults were 1) mirror return is slow sometimes (like a 2 sec exposure); 2) top control wheel stops working altogether - then works again next day; 3) top control wheel occasionally changes focus point every other click when in Tv mode (corrected by removing battery); 4) rubber casing coming away from the body. After 4 weeks it was returned with a very clumsy glue job to the rubber casing and a score mark on the body. Jessops agreed to send it back for "review" and in the meantime lent me a Canon refurbished 40D with just over 1000 shutter actuations according to the image counter. I found that this example also has the occasional slow mirror return, but worse than that, the top control wheel also packed up the other day (though it's working again now).
I was thinking of investing (if that's the right word) in the 5D Mk2 but now I'm not at all sure. My 10D had to go back to Canon under warranty ( a new PCB) and my 70-300 IS also needed warranty work on the IS (which was botched by Canon resulting in them replacing the lens with a new 75-300 IS). One of my friends has a 20D that has been returned to Canon twice for warranty work.
Is this a typical sort of experience for a Canon owner? Or am I just unlucky?
