Definitely...I wish I still had the 14 to compare to the 14-24 on the D3 but I sold it a while back...almost as soon as the 14-24 was announced. I the D3 + 14-24 and 24-70. Spectacular step forward for Nikonians.
In case anyone is looking at this lens... http://www.photozone.de/Reviews/Nikkor%20/%20Nikon%20Lens%20Tests/46-nikon--nikkor-aps-c/361-nikkor-af-s-14-24mm-f28-g-ed-n-test
I used to have the 14/2.8...noooooooo contest in my mind. The 14-24 is razor sharp corner to corner best I can tell. And that shot is NX straight convert - 14mm, iso3200. It's nothing earth shattering but I was impressed...no straightening needed and the noise is gorgeous.
