I received my new AF-S 14-24 from Adorama this weekend and find the wide field of view a lot of fun to work with. However, there seems to be some vignetting at the 14mm focal length and aperture at f/2.8 with my D700. The vignetting falls off, but does not completely disappear, at the 24mm focal length. I do not have vignette control turned on in my camera. My questions are: 1. Is this normal? There are rave reviews about this lens everywhere and no mention of vignetting. 2. Does this have something to do with the lens-camera combination? Would it go away with a D800 for instance? 3. I have the latest firmware in my D700. Is it a software issue? 4. Am I just noticing this because everything else is so great now? 5. Is it my copy of this lens?
I've attached an outdoor example and an indoor example. Thanks in advance for your comments. P. S. - For some reason the metadata didn't come through. Both images are at 14mm and f/2.8.
It is normal. With vignetting control turned off the D700 and D800 will show the same. Actually the vignetting is probably less than most wa lenses. I would suggest using vignetting control in camera or you can correct automatically with the latest Adobe or Nikon software.
Vignetting is present with all lenses to some degree especially fast lenses wide open. Photozone's review of this lens shows there is over 1.5 stops of vignetting wide open at 14mm. There is 0.5 stops even when the lens is stopped down to f/11.
Thanks to all for your comments and especially the photos with the D800. I feel better already; I had been wondering how I could spend this kind of money and get an unexpected result. I'll switch on vignette control immediately. I just never had a need for it before. Nikonians is by far the best source of photographic information I've ever seen!
Lynn -- If you haven't already, you will fall in love with your 14-24mm. It is a magnificent performer at the very top of its range. As suggested, turn on your vignette control in your camera and depend on software to almost eliminate any that makes it through that "wicket." This lens will amaze you when you get used to it. You do have to be careful to get the camera level unless you are prepared for some pretty extreme perspective issues, especially at the 14mm end. But this is just a fact of life with any extreme wide angle lens.
Like all wide angle lenses, the 14-24 is subject to geometric distortions. This makes people at the edge of the picture appear to be overweight with egg-shaped heads. The aircrew might not appreciate this look. To my knowledge, the only software capable of correcting for this "volume anamorphosis" is DxO Pro. they have a free trial.
My suggestion is: Capture in RAW and use post processing to fix the vignetting. With a 14mm lens, you may get more levels of exposure within a frame than in a "normal" scene. The 14bit RAW is much better than 8 bit JPG.

I recently used the 14-24 in a helicopter, shooting from the back seat with my subject turning around in looking back at me from the front seat -- no more than 2.5 feet away. Try to keep your subject in or near the middle of the field and let all the aircraft stuff surround him or her. It makes no difference if that's distorted. Just because you have the extreme wide field doesn't mean you have to put people on the sides! Good shooting!
As stated all lenses have some vignetting, but especially super wides, just the nature of the beast. Leica with their rangefinder cameras and WA lenses, which has the rear lens element very close to the film/sensor plane, had special micro lenses over the sensor sites at the edges aimed inward to help solve this problem. With DSLRs this in ot as critical as the mirror box requires a different design for WA lenses, but the problem is there regardless. The Nikon 14 - 24 WA zoom is probably the best WA zoom currently on the market.

Here's the cockpit photo. I was all the way at the narrow end -- 24mm -- and it is cropped some, but it conveys the idea of keeping the subject pretty much in the middle of the field (use only about the middle half of the field for the subject. Distortion enters progressively the further you go toward the edges and especially the end of the frame) to minimize distortion. I also used an SB-800 flash, bouncing it and shooting in the P mode. That way -- ITTL-BL -- it gave me an exposure pretty much identical inside and outside the cockpit. We did this on the way back from an aerial job for an engineering firm -- that's the owner in the left front -- the pilot knew what I was doing and thus wasn't surprised by the flash. The client was pleased.
Thanks, Alan. Your image above is infinitely better than what I was getting with my older lenses. Your example is what I am looking to capture -- enough clear detail of terrain to provide context for what's going on in the aircraft.
The critical element here was not the lens -- at 24mm, obviously the 14-24 has the same FOV as the 24-70 at 24. Looking at the RAW image, this final product was cropped slightly, so it is in effect, even slightly longer FL than 24mm. I have enjoyed working with the ability the camera gives to balance the exposure between the flash lit area and the background. Whatever mode offers the ITTL-BL modes on the flash seems to work here, although I recommend trying this with a window at home before in an airplane! I hope this gives you what you are looking for.
