47MP Panasonic S1R
Zeiss ZM 35mm f/1.4 Distagon

Aperture Series: Mosaic (Panasonic S1R)

Includes images up to 93 megapixels, 47MP sensor-resolution images, and 24MP images, all downsampled from the 187MP Multi-Shot High-res mode images, plus crops from the 93 megapixel images.

Performance at wider apertures of Leica M lenses and Zeiss ZM lenses is generally miserable on all mirrorless cameras to date (~April 2019) including the Panasonic S1R as used here.

However, this series shows that the Zeiss ZM 35mm f/1.4 Distagon can nonetheless outperform native lenses (!) when stopped down, in spite of the serious damage to its performance caused by ray angle effects of the sensor cover glass. See MTF on Mirrorless Cameras for just how serious the damage is. One wonders what Zeiss could do for a native design.
