As expected from the published MTF graphs.

I have the lens on pre-order.

Looking at the pictures from the link in actual size on flickr, they show many artifacts, pretty bad actually.

Examining real picture files will provide the answers. I see no reason why this lens should be different from the 3 native lenses I already use. They are all uniformly good performers.

It's the first time in my life I pre-ordered a lens. Normally I wait for reviews (from reputable reviewers :) ).
I'm nbr.1 on a waiting list overhere, but I'm afraid I'll have to wait a few months until the lens is available overhere. :(

Unverified reports claim the 14-30 will become available here in April. But unlike other product releases the Nordic countries don't seem to have high priority with the Z items.

Some of the sample images look really good!
I see blooming in the high contrast image, sky and forest and that is a little strange since it is shot at f/10
Some of the other imagers are heavily PP'ed i think so not possible to blame camera or lens,,,


The close up bird shot is really good, sharp into the corners, very similar to 14-24mm f/2.8 AFS in performance I believe

The system gets more and more interesting for a light weight highly capable setup. I sit and watch & I am happy with the wonderful stuff I already have.

Got my 14-30Z today. Apparently Nikon strives to meet demand for it as I had to get the zoom lens directly from Nikon UK and it still hasn't appeared on dealers' shelves over here.

I did have the opportunity to use the 14-30 on the recent NG meet-up in Scotland (thank you, Mikes) so already had some practical experience with it.

The zoom is of the "unlock" kind thus one has to extend it to the shooting position before it can communicate with the camera. Same principle as in the 24-70/4 and while this is all right for travelling compact, it also slows down the initial setup when a motif is spotted, unless you have the lens extended all the time. However the latter defeats the purpose of compacted lenses.

Images delivered are crisp and colours are vividly rendered. Shooting into strong light sources generates only a minimum of flare and ghosts.

What is most surprising for those not relying on Nikon software to process their NEFs is the quite severe geometric distortion of the lens. In-camera jpgs automatically correct and so does Capture NX-D. Photo Ninja is able to remove most of the barrel distortion, however some loss of viewing angle occurs. In the same process the obvious vignetting in the extreme corners also disappear.

The example below is @14mm and is shown without and with geometric correction.

I’ve just ordered mine and can’t wait to see if it can replace my Zeiss.
The distortion at 14mm looks awful. :-\

It does look like after barrel correction, the field curvature was greatly corrected, as well.  OK, it isn't 14mm, but close to 16, after all, what isn't a show stopper to me, at least.  LZ

Thanks for posting this comparison. Does NX-D also crop an image (taken @14mm) in its correcting of distortion? If so, is this zoom then a 15-30 in practise?

NX-D makes a corresponding crop as Photo Ninja. Not sure this means the focal length is significantly different from 14mm, one has to evaluate prime 14mm lenses against the zoom set to the same focal length.

Also, the distortion might not be as evident for nature subjects, plus vignetting likely is much less when the lens is focused closer.

Thanks for the explanation  :) There's also an example on FM, and the cropping penalty appears to be minor https://www.fredmiranda.com/forum/topic/1598734

that distortion made me dizzy  :o :o :o

it reminds me of the 16-35/4 ::)

I am interested in swapping my 24mm 1.8g lens for this lens but the greater-than-usual sample variation worries me. I don’t have a clue how I can check if I have a good sample. Any thoughts on that?

I for one would have kept the 24/1.8. It is a nice and compact alternative to the 14-30.

I decided to wait with purchasing the 14-30mm. I haven't even used the 24-70, 35 and 50mm lenses yet. But that will change soon.
W.r.t. the sample variation risk, the solution turns out to be easy. I can return the lens within 14 days of purchase.
