Joseph Kahn, a director, broke it down on his Twitter:

My read on STAR WARS 7 slate: ND 6 bringing down two stops to a 5.6 stop. Probably long anamorphic lens on close up.

5.6 is a high stop for spherical lenses, but ok for slow anamorphics, especially if looking for more depth of field on close ups.

If shooting on 200 ASA film stock, base exposure at 11 might indicate a lot of light and it's an exterior.

Oops didn't read the Al40. Primo 40mm. That's a wide shot. 5.6 is a medium depth of field, not too shallow. Maybe for a shot with movement.

Or maybe the look is really old school deeper focus and not too shallow depth like they did on Star Trek.

Or its deeper focus for vfx reasons. Filmmaking is so endless in choices haha.
