I have had three DSLR's and have been able to clean the sensors on all but the Canon 1Ds Mark II. The Nikon D100 and Canon 1D Mark II with cropped sensors (1.5 and 1.3) have been no real problem to clean but the 1DS Mark II has been hell. It's so tight in the chamber that getting ANY cleaning device in there without touching the sides is darn near impossible. And now it looks like I may have gotten some Eclipse fluid between the sensor and the AA filter as there is a smuge like thing in the top right corner of the frame that doesn't change with cleaning.
I've tried EVERYTHING: Visible Dust sensor brush, copper hill method, Sensor swabs with Eclipse, and the new SensorKlear from Lenspen -- all to no avail for this smuge so I have to believe the crub is between the sensor and the AA filter. So, if that's the case I'd like to know if any repair is possible by sending it back to Canon or anyone else for the matter. If so, what can I expect to pay?
Thanks,
Brian
