I find it interesting that in 2007 Canon developed a 50MP sensor, then a 120MP sensor in 2010, and in 2011 they seem to be saying fewer MP's are better. Why even work on multiple proof-of-concept sensors like that if the concept is inherently flawed? I think we are being fed some marketing lines (again).
In my film days I never shot higher than 800 ISO and more commonly shot 200 or less. I did, however, shoot 8x10 film partly out of a desire for higher resolution. Is the market really clamoring to shoot in a dark closet, or is that just the next Nikon rivalry now that Canon can make APS-H sensors with 120MP?
It is my hope that after developing the C300 and EOS C, that Canon will get back to making still cameras that focus on photographing stills.
