If you go to a sport game, or a news conference or reporters conference...
you will easy to notice around 1:5 ratio for Nikon:Canon system ...
the above picture show a case ...
However, I still see Nikon and Canon both have good lens and it is just a system choice.
good luck

Canon and Nikon has each of its own.
In my opinion, Canon has more lenses and accessories selection.

Cannon
