Performance
Optical performance is ultra-high and mimics its 35/2 sibling in some respects.
However, with excessive distortion requiring distortion correction, sharpness ends up being highly variable across the frame, ranging from unbelievably crisp to never quite sharp, at least on a 60MP sensor of the Leica SL3. Still, even the corrected image will outperform most 28mm lenses.
