Right, I think I can work this out myself.

The sensor diagonal stays the same on the multi aspect sensor no matter if you are in 4:3 or 16:9 mode. So the diagonal is 21.67mm.

This means the horizontal in 16:9 mode is 18.88mm.

Stick this through the equation for equisolid projection, and you get 152 degrees.

So there is your answer, 152 degrees in 16:9 mode, and 138 degrees in 4:3 mode.
