整个测试报告出来了：

翻译了一把，方便不熟E文的朋友。有错的地方请编辑改正；

作为第一支DX系列的镜头，这支超广角变焦镜是专门为D1系列以及D100数码相机设计的。"DX"的标识表示该镜头适用于现有NIKON数码单反相机中所使用的较小的成像感应设备(译者：CCD)，因此该镜头不能用于35毫米的相机(除非用户不重视边角发虚，以及失光的现象，然而16-24毫米焦端却可以用在F5的机身上)。尽管NIKON的宣传资料中宣称DX镜头具有轻巧的特点，该12-24DX镜头却非如此，实际上它在体积和重量上和14/2.8更为相似(约为0.5公斤)。该镜头的构造性不错，然而我测试的这支镜头的对焦环却有些松垮。这支镜头的口径为77毫米，并使用于17-35以及18-35同样的遮光罩HB-23。最近对焦距离为0.3米。由於使用了AFS，该镜头在对焦时十分宁静和快速。并且因为是内对焦设计，所以在对焦时镜头前端不会转动，而且镜头的长度也不会变化。

巧妙的光学设计以及非球面镜和ED镜片的使用，使得该镜头拍摄的照片具有反差高，色彩饱和的特点，并且对眩光的控制非常出色。Field curvature is negligible and evenness of illumination across the entire frame is remarkable. (译者：该段话不知道如何用技术术语描述比较好，请大家帮忙)。在12毫米端，边角可以察觉失光现象，但是并不严重。在其他状况下，并没有边角发虚的现象，这的确是非同凡响的成就。

该镜头的几何变形十分轻微。虽然在12毫米端可以察觉桶状变形，但情况并不严重，实际上甚至比17-35在17毫米端的情况还要好。在24毫米端，可以察觉轻微的枕状变形。

在24毫米端，几乎所有光圈下的图像都十分锐利。只有在f4以及f22，图像的锐利度才有所下降。F8-F11是最佳光圈，但其他光圈下的成像也都十分出色。在24毫米端没有色散的现象。没有哪一支NIKKOR的24毫米定焦镜能有如此出色的表现。

然而在12毫米端，会出现色差现象，并且图像的锐利度也有所下降。因此在12毫米端，图像的边角明显偏软，除非收缩光圈到F8以下。最佳光圈端在F8-F11之间。

在17毫米端与AFS17-35的直接比较显示，17-35的几何变形比12-24要明显，但是在F8光圈下，17-35的成像要更加锐利。我还没有机会在其他焦端进行两者的比较，但是如果在24毫米端，12-24优于17-35，我不会觉得诧异。

"国内已经上市，最新价：7380。"
在哪里？能说具体点吗？好像价格蛮有诱惑的。口水中...

第一印象出来了，还是芬兰人Bjorn Rorslett：

原文：

AFS-Nikkor 12-24 mm f/4 G ED-IF DX

3.5 (@ 12 mm)
4 (@ 18 mm)
5 (@ 24 mm)

The first offering in a new line of DX lenses, this ultra-wide zoom is designed especially for the D1-series and D100 models. The "DX" designation means it projects an image circle optimised for the smaller sensor size of the current Nikon DSLRs and hence it cannot be employed on 35 mm bodies (unless the user is desperate to maximise lens vignetting and light loss. However the entire 16-24 mm range can be utilised even on the F5).
Despite Nikon's advertised claims about DX lenses being small and light, the 12-24 DX fulfils neither, in fact it is similar to say the 14 mm f/2.8 in size and heft (about 0.5 kg). The lens is quite nicely built, but on my review sample the focusing collar rattled somewhat. The lens takes 77 mm filters and shares the hood HB-23 with current 17-35 and 18-35 Nikkors. Focusing down to 0.3m, the 12-24 DX operates fast and silently as expected from its AFS lineage. It is a true IF design and thus there is no front rotation or change of total lens length during focusing.

The wildly exotic optical design, with plenty of aspherical and ED elements, produces high-contrast images with vividly saturated colours and low levels of flare and ghosting. Field curvature is negligible and evenness of illumination across the entire frame is remarkable. Set wide open at 12 mm, light fall-off into the corners is detectable, but a far cry from being troublesome. Under all other conditions there is virtually no vignetting. A spectacular achievement indeed.

Geometric distortion is low for such a wide lens and although the predictable barrel distortion does show up at 12 mm, the amount is not alarming and in fact much less than found in the 17-35 AFS (@17 mm). At 24 mm, a slight pincushion distortion can be seen.

At 24 mm, very sharp and crisp images resulted at nearly all aperture settings. Only the f/4 and f/22 were slightly less sharply etched. Peak performance occurred at f/8-f/11, but the high image quality held up nearly everywhere else too. Colour fringing was virtually non-existent at this end of the focal range. No Nikkor 24 mm prime lens gives this kind of quality images.

However, towards the 12 mm setting more chromatic aberration occurred and image sharpness in general declined. Thus, at 12 mm the corners were distinctly soft unless the lens was stopped down beyond f/8. Peak performance still was in the f/8-f/11 range.

A direct comparison (@17mm) with the AFS 17-35 mm Nikkor indicated the 17-35 had more geometric distortion than the 12-24 DX, but exhibited slighly sharper images (at f/8). I hadn't the opportunity to repeat comparison at other common focal lengths, but wouldn't be surprised if the 12-24DX got the better of 17-35 at the 24mm end.

The 12-24 DX behaved impeccably similar on both my D1X and D1H, so no nasty surprises like those found with the 14 mm should be expected here.

(The full review is in the works. Stay tuned)

1/640 f4.0 @12mm:

国内已经上市，最新价：7380。

分明是抢钱嘛，好像要10K多啊！！！

3/4那几只镜头和样机看着很威风, 可不知道如何实现Oly吹嘘的'跨平台'兼容性, 难道一台3/4机
能同时用C和N的镜头, 那可真造福人类了

哪为给说说国内何时可以有货？

想问下大家，镜头的焦距在DSLR上是怎么换算的啊？？

你们难道不知道该头只能用于1.5x（？！）（现有） dslr吗？
怎么好和ef16-35比较？！

是吗,这个价还真的比佳能值.尼康头可是向来比佳能贵啊!!
莫非想和佳能~~~~

那么贵，还不如直接上AFS17-35/2.8呢！又可DC/FC两用，比这个实用！

都先等等吧！贵的要命！

1292欧元！在德国已经开始发售了，虽然这是含税价，税率大约15－20％。大家自己算算吧！

我等.....

德国的准确税率是16％，这也是三年质保镜头的价格。推算出来，不含税人民币价格大约是9800到10000元。

我看不值！

听蓝: $700是上星期的消息, 应该算是最新的, 具体还得等三月初正式发布.

curtner: 更搞笑的是连 AF 200/4D Micro-Nikkor和 AFS 400/2.8 也是NCP
但AIS头很多都是NAS, 这个倒不算意外.
