Zeiss ZM 35mm f/1.4 Distagon Aperture Series: Mosaic (Panasonic S1R)

See my L-mount mirrorless wishlist and Leica M wishlist.

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.

This series is remarkable in that by f/5.6 to f/8, total performance across the field stomps on the performance seen with native lenses for the Panasonic S1R, albeit with the downside of accentuated field curvature. It is by far best total performance I have yet seen of any lens yet tested on the S1R, including two Panasonic LUMIX S and three Leica SL lenses (April 2019). Which is astounding, to say the least.

In diglloyd Leica M:
