Or you can fast-forward to the performance at long distances. If you want to see all the details and comparisons, read on. The lens also exhibits only very little field curvature over its zoom range. Nikon’s new zoom lens looks very sharp in the DX image circle throughout the zoom-range with only a slight softening towards the FX-corner – which gets gradually softer towards the long end. Nikon Z 14-24mm f2.8 S 100% crop from center, DX-corner, FX-corner You can jump to the detailed results at different apertures and comparisons with the competition by clicking on the crops of the respective focal length. So you will not see light fall-off in the corners.įirst up is an overview of the wide-open performance at different focal lengths. White-balance was adjusted to a neutral white and I did some exposure compensation to make the brightness of all crops match. 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 10.0/CRAW 13.0 from RAW to Adobe Color profile with the built-in lens profile for vignette, distortion, and CA compensation applied. Let’s see how this theoretical performance translates into real life results in the sharpness test based on Siemens-stars. But the comparison also shows how good the Z 14-30mm f4.0 S is – albeit at a one stop slower aperture. Especially on the wide end astigmatism (and hopefully field-curvature) and corner resolution is greatly improved. The new optical construction has lifted resolution and contrast of the new zoom lens considerably compared to the F-Nikkor. I’ll show you the real-life performance at 4 mm (center), 13 mm (APS-C/DX-corner), and 20 mm (FF/FX-corner) on a 45MP Nikon Z7 camera. 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 line-pairs are together the less astigmatism (= resolution depends on the orientation of the test-pattern) the lens has. These MTF charts show the computed lens-performance of lenses wide open without influence of diffraction.
