This page compares the following at ƒ/9.5:
- 36.3-megapixel Nikon D800E + Zeiss ZF.2 50mm f/2 Makro-Planar.
- 22.3-megapixel Canon 5D Mark III + Zeiss ZE 50mm f/2 Makro-Planar.
- 18.0-megapixel Leica M9 + 50mm f/0.95 Noctilux-M ASPH.
The D800E has a sensor resolution advantage (linear) of 27% over the Canon 5D Mark III and 101% over the Leica M9. But the Leica M9 also has no anti-aliasing filter, so it might compensate to some degree.
A nodal slider was used to match the focus between the cameras to within a few millimeters, based on examining wider apertures beginning at ƒ/2. Even so, the focus is not matched perfectly, and so a variety of crops are shown.
