My three (3) year old 5DMII ceased functioning last week. I am a Gold member of CPS and called them (first time for repairs). Sent my camera body to NJ on Monday. Received confirmation at 1300 hours on Tuesday, that they received it. "It was found that the mirror had shorted causing error 20 to be displayed. Mirror was replaced. Product functions were confirmed. Adjusted exposure. Focus. Shutter Speed. Cleaned CMOS and clecked all to factory specs." Received email on Friday that it was fixed and shipped. Fedex delivered it on Saturday. On my way to test long lenses. Thanks CPS. You saved me a lot of money.
