Hmmm. beyond f/11 is only one other full stop, f/16 - that is the end of the scale of this lens.
At f/11 it is "as bad" as f/1.4, but the corners and borders are more closely to the center, resolutionwise. In practical photography it's very a narrow DOF, you need to focus really precisely on what you want. So, unless you're not trying to make reproductions, you will usually have a limited spot of sharpness in your frame. I think, it's a bit pointless to look for very high resolution over the whole frame.
Here I missed it, but if I look at the feathers, it's hard to complain:
For me it's as well a perfect lens for handheld nightshots
And improving my AF skills (or the knowledge how the AF will see what I want to be focussed) is one nice side effect. Matter of fact, I already changed some habitudes.
