Seems this hole "black dot" issue is really starting to haunt the otherwise excellent reception of the MKII: "Had the EOS 5D Mark II not suffered from the black dot issue, it would have easily earned our highest recommendation. It’s one of Canon’s most powerful DSLRs to date, capable of delivering superb image quality with decent handling and all the latest bells and whistles. The movie mode is also an excellent addition, and while it’s not a practical replacement for a camcorder for most amateurs, the results can be spectacular and independent film makers will love it. Indeed its testament to how good the 5D Mark II is that it can be highly recommended as a still-camera alone, or a movie camera alone."    Link
