I need your advice on a matter.
Until recently, I owned a 1DS and have been using it mainly for studio work . Almost all the work was Jpg though some was RAW. I never really had the need to use it above 200iso and as far as I could tell, apart from a sensor clean, not much else was needed.
I recently sold it to a guy in Estonia.
The guy there tested it and at 5ooiso found 1 hot pixel in RAW (not jpg). He's since had it cleaned and the pixel cannot be righted. He's been quoted over £4000 for a new CCD.
Q. Does it devalue the camera? If so by how much? Morally I feel obliged to offer something back, but how do I gauge a thing like this. He says he will loose money on any subsequent resale.
Your opinions please?
