Build quality is impressive, and the aperture ring is nicely weighted, an improvement over the 14mm and the Zeiss 12mm in my opinion. I'm not keen on the plastic, petal shaped hood, especially as it was Fuji who followed Leica with the more effective squared hoods. It's not flocked with felt either, which I prefer. I've had the lens for a few days now and thought I would add a few samples. I'll be adding more in due course.

At 100-percent actual pixels (taken from the extreme corners) there are some slight double edged effects consistent with slightly over-corrected designs.
