This two-way comparison pits the manual focus Zeiss Loxia 25mm f/2.4 against the autofocus Zeiss Batis 25mm f/2 Distagon. The two lenses have quite different behavior and one is certainly my favorite for landscape and anything static.
Evaluated here are sharpness across the field (particularly at f/2.8 through f/5.6), field curvature, and (oddly enough!) field of view.
