Zeiss Otus 55mm f/1.4 APO-Distagon Aperture Series: Surviving Aspen (Nikon D850 monochrome)
The Nikon D850 monochrome is a Nikon D850 with its color filter array (CFA) removed by maxmax.com. The NEF files are converted to monochrome DNG via LibRaw Monochrome2DNG and “Method B”, then processed using Adobe Camera Raw. Doing so avoids any demosaicing and thus retains full spatial resolution.
This aperture series shows the Zeiss Otus 55mm f/1.4 APO-Distagon from f/1.4 through f/11 on the Nikon D850 monochrome using a B+W Dark Red 091 filter.
