The image samples show a softness at the borders, only partly due to CA. With the CA corrected, the images should respond well to a good sharpening technique in post processing, so it should do reasonably well for wide angle "landscape" shots.
See this photo at f5.6, it is not the greatest but it will sharpen up well:

As stated above, the Voigtlander 20mm f3.5 SL II N wil do well too, it is pretty sharp stopped down and at landscape distances. The Voigtlander performs better than tests have you believe, due to its astigmatism at close (MTF testing) distances.
