Why my new Canon 80D is better than a Nikon D7200.
Quite frankly, it isn't; it's different but not better because as a tool, they essential do the same thing.

The 80D is better for me than a D7200 because I already own every XXD series camera Canon has manufacturer so I'm real familiar with how it works. Add that to the 5Dsr, 6D and 7DII that I own and it's easy to figure I probably have a whole lot of lenses that will work on the 80D but not a one that will work on a D7200.
Does Canon make better cameras than Nikon or Nikon better than Canon?! Don't know, don't care! It's not so much who has the better tools but who can use the tools better.
