Order: Zeiss ZM 35mm f/1.4 Distagon at B&H Photo.
A “wall test” is a very demanding test indeed, because any lens with field curvature will have a difficult time making a sharp image at f/1.4. But the Zeiss ZM 35mm f/1.4 Distagon sets a very high bar that no Leica M lens can match. So it is best to show just what it can do.
With HD and UltraHD images to full resolution, and large crops, from f/1.4 through f/16 along with large crops.
