why has the 16mm f2.8 got such a bad rep?

Good catch! People seem to love bashing this lens, which even in their tests shows reasonably good central sharpness, despite the corner fall-off (as much due to field curvature as anything - did making a 16mm so small require the very convex front element which might cause that?).

It isn't field curvature on my lens. Those corners cannot be made sharp even if I focus on them.

Check the MTF chart. This lens, by design, has very soft corners.

I would be fine if Sony sold it with verbiage explaining it is a special use lens:

This lens is optimized for compactness and low price. The corners are not up to general Sony performance standards, especially at apertures wider then f8.
