قابل توجه دوستانی که در مورد CA ی آن نگران بودند ...

Very fast lenses often experience problems with the longitudinal chromatic aberration. Nikkor is not an exception to the rule and that aberration is especially bothersome in its case. What’s more, on stopping down the aperture we see it decrease but not very satisfactorily. As you can see in the crops below the aberration remains clearly visible even by f/2.8.

و نقاط و ضعف و قوت, و نتیجه گیریی که در آن با Samyang 85 f1.4 هم مقایسه شده!!

Pros:

* high build quality,
* splendid image quality in the frame centre,
* very good image quality on the edge of the frame, even on full frame,
* slight lateral chromatic aberration,
* negligible distortion,
* well-corrected coma in the corners of APS-C/DX sensor,
* sensationally corrected astigmatism,
* slight vignetting on APS-C/DX sensor,
* quite good work against bright light,
* fast, silent and accurate autofocus.

Cons:

* significant vignetting on full frame,
* a bit too high coma in full frame corners,
* distinct longitudinal chromatic aberration.

If you were a perverse and malicious being, you would start the summary of this test this way: although the Nikkor AF-S 85 mm f/1.4G costs almost 1700 $, it gives us more or less the same the image quality at the maximum relative aperture as the Samyang 1.4/85, which costs about 300 $. What’s more, the aforementioned Samyang corrects chromatic aberration, distortion, coma and vignetting better than the Nikkor and allows us to work with higher precision in the manual mode …

However if you want to be not only malicious but also honest you should add several other things here. Even after a slight stopping down the Nikkor is significantly sharper than the Samyang and also the Zeiss. On the edge of the frame it gives us the level of sharpness unparalleled with any 85 mm device tested by us so far, including the expensive Canon 85L. Weaker coma correction is compensated in excess by the sensational level of astigmatism correction. It works well against bright light, it features a superior build quality and, what’s important, it has a silent, quick and efficient autofocus.

Is it worth spending such a huge amount of money on it, though? Everyone must answer this question on their own.

بررسی مختصر Neil vN

و دو عکس با 2 لنز 85 اف 1.4 نیکون ؛ نسخه جدید و قدیمی که با دو D3 با تنظیمات یکسان در دوربین و هنگام پروسس گرفته شدند, به فاصله 30 ثانیه , بیشتر برای مقایسه بوکه دو لنز (که تقریبا ً فرقی با هم ندارند گویا)


Nikon 85mm f1.4G

..
.
Nikon 85mm f1.4D

و توضیح عکاس در مورد تفاوت کنتراست و اشباع دو عکس :

Notice how the flare from the background washed out the contrast, as you can see in her black sweater. Now, the image at the top is noticeably warmer. I did subsequent tests, and the f1.4G is indeed slightly warmer than the f1.4D comparing the two lenses on two identical camera bodies, cross-swopping the lenses. But the difference in warmth of the images wasn’t to the extent shown here. So I am assuming what we see in these photographs is entirely due to the flare from the blue-ish / purple-ish tree leaves

و خلاصه ماجرا

Final initial assessment of the Nikon 85mm f1.4G
– focus speed is greatly improved,
– focus accuracy is improved,
– and the new lens handles flare like a champ.

Alternatives

Nikon 85mm ƒ/1.4D AF ~$1,100
The biggest comparison will be with the previous version of the lens. It's almost an apples-to-oranges comparison: the D version of the lens had a very different sharpness profile, almost tailor-made for portrait work at ƒ/1.4, where the central region of the frame was moderately sharp, and the corners were soft, perfect for subject isolation. The new version adopts a different profile at ƒ/1.4, where corner sharpness is indeed much improved, but there is the odd 'sombrero effect'. Vignetting is slightly improved, but otherwise, CA and distortion are about the same. The addition of the AF-S motor makes the lens usable on consumer bodies, and much easier to use (the older AF/MF button switch isn't loved by many) but the AF-S motor is much slower.

Conclusion
So this is a tough one.

There is a lot to like in the new Nikon 85mm ƒ/1.4G. The addition of nano-crystal coating will help to contend with flare issues that were something of an issue with the previous 'D' version of the lens. The new AF-S motor makes focusing a snap: if you want to override autofocus results, just turn the focus ring. Much easier than the manual-auto focus switch on the 'D' version.

Edge-to-edge sharpness is radically improved in the G version of the 85mm ƒ/1.4, when compared to the D version. However, the $1,700-question: is this an improvement? The 85mm ƒ/1.4D was for many, the go-to portrait lens, and in part, this was because of the corner softness produced by the lens at ƒ/1.4. The new version of the lens removes this factor, and unfortunately, doesn't produce super-sharp results at ƒ/1.4 for the trouble. Rather, we see 2-3 blur units across the frame (on the D3x) with a slight 'sombrero' effect. Lastly, longitudinal chromatic aberration is (still) a factor when the lens is used at large apertures, producing red fringing in front of the focal plane, and green fringing behind it.

Don't get us wrong. When stopped down to ƒ/4, the 85mm ƒ/1.4G produces very sharp results. But this is a lens that people will be buying to shoot at ƒ/1.4, not ƒ/4. Otherwise, why not just buy the much less expensive 85mm ƒ/1.8D, which is also tack-sharp at ƒ/4?
