I need to take a bunch of business photos like this using our Canon 5D MarkII:

Because they will be taken inside a small office I'm worried that a 85 f/1.2 might prevent me from getting everyone in the scene as I won't be able to get back far enough. So then I thought about the 24-70 f/2.8 but am concerned that 2.8 won't give me a shallow enough depth of field. Maybe the 50 f/1.2?
