I don't have the ability to do a scientific comparison.
But I do experience different lenses in different ways.
I am heavily into Fuji X. For a long time, my favourite lens was the 14mm, an outstandingly accurate and distortion free lens, as is generally acknowledged. Then I acquired the Fuji 16 mm. This is now my favourite lens. It is not the AoV. The images I make from this lens make me catch my breath in a way that the wonderful, accurate, 14 mm images do not.
Help!
