Thanks, very cool info... I too noticed these AF improvements but I thought they were mainly related to the algorithms than the hardware itself. Mind sharing where you found this info so I can quote it elsewhere?

Hi Geno,
This info was in one of the Canon papers they produced when the cameras were introduced.
Of course I had to try this out, and I found that in tungsten, halogen and fluorescent light AF was remarkably better than with the 40D and 5D classic indeed, let alone artificial mixed light. Other than that the AF algorithms have been improved as well as far as I can tell. The 50L is a good example of that. My 50L focuses well within Canon specs at all distances and apertures, but on the 40D and 5D it occasionale missed focus completely and utterly. About 1 in 20 shots or so with the 40D, and a bit less with the 5D, but on 50D that certainly was better (couldn't get it to do it, but only borrowed, never owned one), and I have never had a problem with the 5D II in this regard.
A very happy New Year to you too!
Kind regards, Wim
