Thanks for shooting these additional shots. Sorry the lighting was not the same, but seems consistent between these two lenses.
First, a question: I see (apparently) that you did not use CA correction, based on the color fringing on the 17mm end, correct? Did you use the lens profiles? I'm surprised how bright and consistent the frame is from side to side on both lenses, even considering that they are shot at f/11.
Second, I see a tremendous difference in sharpness between the two lenses when viewing details like tree branches, trash on the ground, and cracks in the lane dividing cement K-rail. The softness and "smudging" go into the frame up past the lamp head and pole, well into the main part of the image again of the zoom, even at f/11 -- makes me remember how awful my 17-40 looked at f/5.6 on the sides and corners. I think this goes well beyond the sensor rez, considering the centers are probably both sharper than the 14mm edge at f/11 (unless diffraction effects are influencing). I don't think the sensor is the culprit -- I've seen nicer rez with my 5D2 and 1Ds3 for finest detail in things like fine tree branches and cracks in rocks, etc.
I don't deny the need for more sharpness in sensor, whether Canon's 21MP or Sony's 36MP -- I'd always enjoy it being affordably sharper!
