That probably will be enough for the next ten years... ;-).

I had a look in my LR catalog, interesting. I couldn't find how to select
on used aperture though?
But I do vote for the fixed ultrawide as well. 8-9mm would be OK for me,

I wouldn't care as long as it is sharp in the corners. I love the 9-18mm
(5K from 13K shots with the E-M5, I just learned (thanks!)), but it is not
really sharp at 9mm in the corners.
C'mon, small, light 7/4.0!!!

Without the sensor stack a 7mm would still be necessary kept some distance
from the sensor because of the shutter, and the 'pixel buckets' forcing
retrofocal design to prevent to steep angled light rays to the borders of
the sensor?
