I am seriously considering getting the 24-70 for use with a D700. I have read a number of posts/threads here...and elsewhere concerning this lens. One of the most recent was an extrememly long one re. light leakage?!? Some have said there are back focus issues. Some have said it's "good, get it" etc. etc.. I would like to know....are there any pros using this lens this lens on a regular basis...that would say yea...this is a FANTASTIC lens...a must have (for zoom in this class/type)...get it asap...worth all the money. I just never get the impression of the above from reading posts on this. I would like to get the staight dope. Thanks. (Note that I did read the KR "report"...but I don't want just one source)
It's an excellent lens with a couple of "gotcha's", so it depends on whether one of the "gotchas" is going to be a deal breaker for you.
Item #1 is that it is a poor 24mm lens. Very sharp in the center, quite average in the corners. Okay for photojournalist work, but not good for landscape. When I need to shoot at 24mm for landscape, this lens won't do. Even if you stop it down, to say F/11, it never gets "excellent", only perhaps "somewhat acceptable", which is a shame given how good it is in other parts of the focal length range. By 28mm it gets much, much better.
Item #2 is that there is light leakage on super long daylight exposures. Cover up the plastic distance window with black tape and you'll be fine.
However, if you think about this lens as being a 28-70 instead of a 24-70, it is quite excellent in that range from 28mm and up. I own most or have shot with most of the Nikon primes in that 28-70 range and to date I have not found one that is significantly better. In a lot of cases I prefer the image from the 24-70 to the prime. Note however that I have not shot with the 45 PC-E, which from the looks of imagery I have seen, is quite excellent. Really the only lens in that range that I currently own that is a distinct step ahead is the new 70-200/2.8 VR2 zoom, which is so stupendously good I almost feel it came as a gift from a superior life form on another planet; that lens at 70mm is distinctly superior to the 24-70 at 70mm, but that is about it.
But again, if your intent is to shoot in that 24-28mm focal length range, it is not going to be the best option for you. There are some rumors floating about concerning new Nikon lenses to be announced in February. Most think a 24 or 28mm fast prime will be one of them; some feel a 16-35 type of lens might also be in there. If you are not in a hurry it may be prudent to wait a month and see what gets announced.

ps: Mike Johnston wrote an interesting article a few years ago; check the last paragraph (in italics, near the very end) where he discusses the Nikon 24-70, I think it summarizes my feelings on this lens quite well.
