Can you combine these two?

This is the short answer:

No! This combination is not compatible

The camera and lens you have chosen cannot be combined. Here is a longer answer:

A non-Canon lens on a Canon camera

This is a Nikon lens and unfortunately they are not constructed to work with Canon cameras. If the lens would have been a Sigma, Tamron och Tokina it would perhaps be different since they are available with a compatible Canon mount.

APS-C sensor is needed

The camera does not have a APS-C sensor which is needed for this lens.
