This is the short answer:

The camera and lens you have chosen can be used together but you will only have manual focus.

Lack of Autofocus

The lens supports autofocus but neither the camera nor the lens has a built-in autofocus (AF) motor. You as a photographer will not have the possibility to use autofocus to obtain a sharp image. Focusing manually will then be the only way to obtain sharpness.
