Despite the differences in focal range, both lenses actually exhibit similar optical artefacts in the corners when zoomed all the way in or out. At its widest focal length, the DT 11-18mm exhibits noticeable softening in the corners at larger apertures and only gets this under control when stopped down quite significantly. Zoomed-into 18mm though, the DT 11-18mm delivers a far superior result, with only slight softening in the corners at the maximum aperture and a good result as you stop it down.

While it's interesting to compare the similarities between each lens zoomed-out and zoomed-in, the really important comparison is when both lenses are set to 18mm. In this instance the DT 11-18mm delivers a far superior result, so once again if you own both lenses and are shooting at 18mm, use the ultra wide lens in favour of the kit zoom.
