50mm on a cropped body is pretty long. Even if the focal length was good, in the scenario above you'd probably find depth of field too limiting when using it wide open. If you were further from your subject/scene, then the depth of field would be as much of an issue.
VR would help though, provided your subject wasn't moving.
