Nikon Nikkor AF-S 14-24mm f/2.8G ED review: A very impressive ultra-wide performer on the Nikon D800?By Kevin Carter - Wednesday April 10 2013 Lens Review
With a DxOMark score of 28, the Nikon AF-S Nikkor 14-24mm f/2.8G ED performs very well for an ultra-wide zoom. Mounted on a Nikon D800, it performs at a similar level to its stable-mate, the AF-S Nikkor 24-70mm f/2.8G ED.
Again, given the extra-ordinary angle of view of this zoom, at 17p-Mpix the Sharpness score is very good. You would expect the distortion to be an issue with a zoom like this but at averaged at 0.4% (actually 1.1% at 14mm) it’s very low.
On the flipside, vignetting at 14mm is quite high. Our averaged score is -1.6EV but wide-open at 14mm this is was quite significant at -2.4EV measured across the field.
Between 14-16mm, the lens also has quite high-levels of chromatic aberration, which may be noticeable at times in the corners of the frame. A concentric ring of chromatic aberration around the centre of the image field was also apparent in our tests, but may be more difficult to see in photos.
Overall, however, the image quality is very high. An average of the metrics, the DxOMark score map shows that image quality remains high to f/8 where the effects of diffraction can be seen to begin to degrade the image.
