This lens has an outstanding contrast, colour rendition and dynamic range.
It delivers very pleasant pictures, which need very little post processing, even in high contrast scenes or difficult light.
It is very resistant to flare and shows very little distorsion fo such a wide field of view (15mm is 22.5mm FF equivalent).
Due to field curvature, it is not a lens for those looking for corner to corner sharpness: the focused target will be tack sharp, even at f4 and close to a corner, but keep in mind that if your target is a distant landscape, the focus will be further away in the center and closer to the photographer in the corners.The only way to mitigate this is to close the aperture around f8.
Yet, in real life, this may not matter because your subject may often include a closer foreground near the border of the frame, or you will appreciate the main target on which you have focused to pop out in kind of a 3D effect.
It is my favorite landscape lens.
