That shot is exposed about the way I'd expect - the camera tries to average all the tones out to middle-gray, and that's about what you have. You want it brighter - you can set the camera to +2/3 exposure compensation, or you can brighten it in post processing.
Nothing wrong with your lens or your camera.
But your monitor? Maybe...

He'll be thrilled! LOL
You don't need any equipment to adjust brightness and contrast, just for color calibration. Since your issue is brightness, adjust on this chart:
