The 70D uses an ALL-NEW focusing system for Canon...and after the debacle they had with their pro flagship 1D Mark III camera model, 18 months of failed focusing, they just replaced it with the 1D Mark IV series, so it **is* very possible that there is a serious issue with the 70D and focusing. Nikon had the huge issue with the D800 and the "left side focusing issue", on what Thom Hogan estimated was perhaps 20 percent of D800 cameras shipped! I watched the ENTIRE video and all the test results above: there does seem to be a very troubling problem with a disparity between viewfinder and live view focusing with that fellow's 70D and multiple Canon lenses. Now that we have moved up into the 18 to 36 megapixel file sizes, focusing issues that were once hard to see are now EASILY seen at 100% pixel view on today's good monitors.
It could very easily be a simple case of bad components, or sub-par assembly, or out-ouf-specification components or assembly, or a little of either. The important thing to realize is that when it comes to defective photo gear on the internet, there will be people who have FINE samples, and will swear up and down that, "There is NO issue at all!" with such and such product. But the thing to realize is just because one guy has a perfectly-operating Widget Mark II that not ALL Widget Mark II units are therefore free of defects in workmanship. The fanboys will rush to defend the product, and try to convince all who will listen that the entire production run of Widget Mark II units are flawless in every way.
Uhhhh, no. No they are not "all" perfect.
Google Canon 1D Mark III focus problems. Google Nikon D800 left side focus problems. Google Canon 70D focus problems.
Ever since we moved UP, and beyond 6 to 8 megapixels in d-slrs, focusing issues have become more and more an issue in critical use situations.
