A quoi voit on la distortion ??

The 18-105mm ƒ/3.5-5.6 provides very sharp results, at least as good as its recent contemporaries and better than previous designs in the same focal length range.
Perhaps the best word to describe the sharpness profile of the 18-105mm is 'consistent'... shows excellent performance at all focal lengths.Chromatic aberration is present in images produced with this lens, but only most noticeably when used at its widest focal length (18mm). CA is generally well-controlled at all focal lengths,Vignetting'')
The 18-105mm does show some evidence of corner shading, but its presence is fairly subtle. If you demand absolutely no corner shading in images produced by this lens, you'll have to use it at apertures of ƒ/11 or smallerAt the wider angle focal lengths (18-21mm), distortion is distinctly of the ''barrel'' type, with the center of the image pushing outward from the middle. This form of distortion is easier to correct in image post-processing software, ...
From 24mm onwards, we see a complex distortion profile: the edges of the image exhibit pincushion-style distortion ... Straight lines will show the ''moustache'' effect, where they bend one way at one edge, another way in the center, and then back the first way at the other edge. This form of distortion is fairly consistent from 50-105mm; fortunately, it's not especially severe, at around 0.4% barrel distortion in the center and -0.7% pincushion distortion at the edges.
