That depends of the size of the subject.

... and the type of camera you've got.

if not action, the ef-s 55-250. If you do shoot action the ef 70-300. These are the best options for the canon.

Now if you need to indoor action, then it will get expensive.

Here's an answer the OP can work with. One part of the equation is length of lens. Aperture, light and consequent shutter speed are the other parts. These calculators can clear up some of what appears to be mystical knowledge. From
