Nikon 14-24mm performs well on the FPS and IQ250. I have tested without the hood shaved and I would expect it to cover, if not 100% then 95%...

Also this was the best performing wide angle out of a bunch of fast (f2.8 or faster) Canon, Nikon and Zeiss that I tested. Least distortion, least vignette, least colour shift, flare and sharpness imperfections towards the edge.

The vignette of the 14-24mm is around a stop as compared with the Zeiss15mm and some other wides that are 2.5 stops. This is vitally important shooting in low light as the LCC adjustment will rip the edges apart as it brightens them.

My tests were field tests at night, as opposed to 'lab' tests. My goal was to quickly determine the best combination on the FPS for the subject and then carry on with the work...

Unfortunately - as anticipated - it doesn't come anywhere near to covering the IQ250 sensor:
