My favorite camera body is my 1D X. This is my primary body that I use. With super fast frame-rate, and High ISO capability I am able to shoot action sports both inside the gym and out on the field with little to no concern about low light performance.

My secondary body is the Canon 7D Mark II. I previously had the original 7D, which was a great camera, but this new 7D Mark II is a step up with a higher frame rate and better low light performance. This is the camera I would recommend for anyone interested in shooting action sports that can’t justify the expense of the 1D X.
