Wide-angle fixed focal lengths

If the correction cannot be switched off, there are high scores for the category distortion when evaluating the JPEG files. In this comparison, the Sigma 2/24 mm DG DN Contemporary suffers from this, which would probably have achieved the super seal with correction. However, the same applies to the Canon RF 1.8/24 mm Macro IS STM, the Nikon Nikkor Z 2.8/26 mm and the super wide-angle Panasonic Lumix S 1.8/18 mm: make use of their strengths!
