Or you can fast-forward to the performance at long distances. If you want to see all the details and comparisons with the reference zoom in its class, the Nikon 24-70mm f2.8E VR, read on.

The lens also exhibits only very little field curvature over its complete zoom range. Further towards the long end there is some variation but all-in-all the corner resolution stays at a good level.

Only the FF/FX-corner shows varying sharpness at different focal lengths: It’s weakest at 24mm with a high degree of astigmatism but sharpens up quickly at 28mm already. Nikon’s new lens is very sharp in the APS-C/DX image circle throughout the zoom-range. Nikon Z 24-70mm f4S 100% crop from center, APS-C/DX-corner, FF/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. Removal of lateral color aberrations is ON, longitudinal CA are not corrected.įirst up is an overview of the wide-open performance at different focal lengths. 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. 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 8/CRAW 11 from RAW to Adobe Color profile with the built-in lens profile applied. Let’s see how this theoretical performance translates into real life results in the sharpness test based on Siemens-stars. The 24-70mm f2.8E VR shows its hallmark performance at 70mm where overall contrast and the reproduction of fine details stays almost the same across the full-fame sensor: not bitingly sharp in the center but one of the best performances of a standard zoom towards the corners. At the long end the new lens shows very high resolution up to 7mm image height at f4.0 but drops below the 24-70mm f2.8E VR (again: at f2.8) from 10mm onwards with a gradual decline towards the full-frame corner. Keep in mind though that the 24-70mm f2.8E VR is shown here wide open at f2.8 while the new Z 24-70mm f4S is measured at f4.0. Not so much in overall contrast (red lines) but in the fine detail where the older Nikon has a distinct drop at 10mm image height and then again towards the extreme corner of a full-frame sensor.

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 46MP Nikon Z7 body.įrom the charts the new Nikon Z 24-70mm f4S should have an advantage over the Nikon 24-70mm f2.8E VR at the short end. 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.
