Why WB1000 has to be A superior?

Central and peripheral image quality A camera with wide angle must produce good image quality in wide angle. That’s what WB1000 is like. In 24mm widest angle, it shows stable expression not only in central area but also the peripheral area. Dropping of the quality in peripheral area is inevitable in wide angle, but that area is very small and minute. Out of the competing models that offer wide angles, I think this one shows the best stability.
