I chose a day with good visibility but the overcast sky means that the contrast of the scene is not as high as usual.

All shots were made at ISO 64 and image stabilization switched offĭuring the period of testing atmospheric conditions were far from ideal. To compensate for any focus-shift I used autofocus at each aperture. Noise-reduction is set to 0, sharpening to 50/0.5/36/10, with no extra tone, color, or saturation adjustment. Processing was done in Lightroom 10.1/CRAW 13.1 from RAW to Adobe Color profile with the built-in lens profile compensating CA, distortions, and vignetting.

Therefore I present another series of test-shots of a city around 1 km away. But performance of lenses also depends on the shooting distance. The Siemens-star test-targets are shot at a distance of 45x focal length (i.e. The test also revealed a little field curvature. Overall Nikon’s new Z 50mm f1.2 S lens is a clear improvement over their DSLR designs and matches the very good performance of the Z 50mm f1.8 S. Nikon Z 50mm f1.2 S compared 100% crop from center, DX-corner, FX-cornerĪbove: Nikon Z 50mm f1.2 S at f5.6 also available at f8.0, f11 The following 100% crops show the Nikon Z 50mm f1.2 S from f1.2 down to f11 compared to the Nikon Z 58mm f0.95 S Noct, Nikon 58mm f1.4G (on FTZ adapter), and Nikon Z 50mm f1.8 S. So you will not see light fall-off in the corners. White-balance was adjusted to a neutral white and I did some exposure compensation to make the brightness of all crops match. Processing was done in Lightroom 10.1/CRAW 13.1 from RAW to Adobe Color profile Adobe Color profile with the built-in lens profile compensating CA, distortions, and vignetting. Let’s see how this theoretical performance of Nikon’s new Z-Nikkor translates into real life results in the sharpness test based on Siemens-stars. And one thing is clear: the new Z-Nikkors all outperform the older F-Nikkor 58mm f1.4G – even wide(r) open. But there is a slight dip in sharpness at 10mm image height and some astigmatism or field-curvature at and beyond the DX-corner. I’ll show you the real-life performance at 4 mm (center), 13 mm (DX-corner), and 20 mm (FX-corner) on a 45MP Nikon Z7 body.įrom the charts the new Nikon Z 50mm f1.2 S shows less drop-off in sharpness and contrast in the FX-corner than the other three lenses. The x-axis displays the distance from the optical axis (=center of the sensor) in mm. Higher values are better (more contrast) and the closer the dotted and solid lines are together the less astigmatism (= resolution depends on the orientation of the test-pattern) the lens has. These MTF charts of the Nikon lenses show the computed lens-performance wide open without influence of diffraction at 10 line-pairs/mm (in red) and 30 lp/mm (in blue).
