Looking at 15mm (note where in the image the Biogon drops down below the 30% mark) on we can see a rather stark difference in what is reaching the sensor. Putting the Biogon on a crop and we get a nice benefit of not seeing how it really performs in the edges/corners. Putting the Biogon on FF and suddenly we get what we asked for.
Even the wider 25mm fares differently from the different design in the outer areas.
