AFS Nikkor 14-24mm 1:2.8G ED  is one of the 135 wide angle lens that can be used for DB (33x44 sensor) with excellent image quality.

The image is taken with a 9 micron DB.
Please see the crop, the moire, which indicates that the resolution of the lens exceeds the limit of the DB.

The image circle of this lens at focal length from 20mm to 24mm is about 60mm.

Wow, the DB is Aptus 17.
If a higher resolution DB is being used (such as DB with 7 micron or smaller), there will be lesser moire.

Wow, see the result of the ouput from an Aptus 65 (not on the same day).
Obviously, the NK 14-24 cannot out-resolve this DB -> so NO apparently observable moire !

Zoom at 24mm
