Photos taken through the ultra-wide angle sensor display a considerable amount of
barrel distortion, which becomes more apparent if the composition isn't right.
But it does suffer from some minor radial
barrel distortion, causing straight lines to curve as they move away from the center of the frame.

In terms of distortion, the 26mm lens has fairly well-controlled
barrel distortion. We do see some chromatic aberration around the edges in some of our sample shots, but only in situations of strong contrast brought on by a strong backlight.
Distortion stretching the shape in the diagonal direction is called pincushion distortion, and that which compresses the shape in the diagonal direction is called
barrel distortion.
However, the initial few photos that we took had the same amount of
barrel distortion seen on the Galaxy M20's camera.
We also noted a slight amount of
barrel distortion. The Nikon also exhibited more internal flare than any of the other models.
The ultra-wide angle lens also has high
barrel distortion making straight lines appear curved.
