of course canon entered the graveyard long time ago..
- insane expensive equipment
- MANY less features comparing to nikon gear
- slow production rate.. anouncing outdated products before even released (check 6D vs D600)
D600 is out and selling like crazy, while canon 6D hasn't even produced from the factories with half the features rumored at the same price
Canon sensors are crappy lower DR ISO,
and of course you can "do" photography with a cheap camera as well BUT in the terms of quality and budget, Nikon offers MUCH more features and canon just follows
The most revolutionary Canon product ever was 5D mark 2 back in 2007-2008. Canon died after that.
