| Re: 1DIII sensor cleaning feature I have had my 1D3 cleaned by Canon after they left glue on the focussing screen during the replacement of the sub-mirror assembly. It was returned spotless and since then, January 08, the sensor has needed no intervention on my part to clean it. I check it regularly and there is no dirt discernable even though I've changed lenses hundreds of times in the interventing period.
cheers
