I would check your focus with live view to determine if it's lens or camera body. Live view and viewfinder use different systems for autofocus, Canon has had a huge problem with viewfinder autofocus consistency with the 7D and now the 70D.
Good luck, I'm wrestling with the save viewfinder autofocus incosistency on my 70D.

I also think it is camera motion or shake. As nothing seems in focus. With a 50mm lens at f4.5 one would think something would be in focus. I am not a fan of ths Canon lens. I have never been but lots of folks are and they like it.
I agree the lens may be faulty and you must confirm it is OK
