The fact is rising tide lifts all boats.
I am not concerned one bit about videography for myself, yet the fact that Canon seems to fall behind in prosumer or low end pro videography behind Panasonic and Sony is unfortunately going to affect revenues. If Canon decides not to bring what is now standard or expected to sub-10K cameras it will definitely affect their bottom line. 5DII used to be the definitive line in HDSLR filming, now GH4 and A7s are much better it seems. Even Black Magic was said to be better than the 5DIII.
Similarly, Nikon has brought lots of great new features in the D810. I am not concerned that my 5DIII doesn't have it, but I would like Canon to bring out a camera that does have all those features so they don't lose customers. A high-res high-DR sensor would certainly help.
I would like Canon to flourish because it will affect me indirectly and allow me to use the great equipment they bring out. I am concerned that Canon's business strategy (which often overrides market surveys for big companies) might be too conservative.
I agree 110%. Sony absolutely has plans to take marketshare from Canon and Nikon. The question is will Canon respond or keep nickel and diming us with incremental updates?
Sony has a lens problem. The other issue with AF and other rough edges would take maybe two or three new generations of cameras to work out. I think we will see Canon and Nikon users switching in big numbers.
Do people not remember the 5d mkii? The mkiii is a revolution in auto focus and low light performance... nickel and dime in the rebel line... sure... but the 1dx is reportedly amazing and the mkiii is borderline great. How soon we forget.
