The Nikon 28mm f1.4E ED is a medium wide-angle lens designed for bodies with full-frame sensors. Announced in April 2017, it fills a gap in Nikon’s wide lineup which previously only offered wider and longer 24mm and 35mm options with bright f1.4 focal ratios. Nikon’s equipped its new 28mm lens with an electromagnetic diaphragm mechanism, nano crystal coat plus fluorine coating on the front and rear lens elements for easier cleaning, and also hardened the lens barrel with additional sealing against dust and moisture. This makes the gold-ringed lens fit Nikon’s line-up of professional lenses and they charge accordingly: 2000 USD / 2400 EUR is the list-price for this new lens.
To find out how the new Nikon 28mm f1.4E ED performs I tested it against the Otus 28/1.4 from Zeiss.
Facts from the catalog
As usual I’ll have a look at the technical data first. I’ve rated the features with a [+] (or [++]), when it’s better than average or even state of the art, a  if it’s standard or just average, and [-] if there’s a disadvantage. I’ll compare it mostly with the Otus 28/1.4 from Zeiss (“Otus” for short).
Size (diam. x length): 83 x 101mm (3.3 x 4.0in) without lens hood. This is large but not overly so. The lens hood adds another 38mm in length and has a diameter of 99mm. The Otus is much larger at 109 x 127mm plus 41mm for the lens hood. 
Weight: 645g (22.8oz.) plus 29g for the plastic lens hood. The Otus weighs double that at 1310g + 62g for the metal lens hood. 
Optics: 14 elements in 11 groups which is a little simpler than the 16/13 of the Otus. The new lens has two (extra) low dispersion and three aspherical elements. Nano coating should reduce flare and ghosting and fluorine coating on the front and rear lens elements “actively repels water, dust, and dirt” and should make for easier cleaning. [+]
Closest focus distance/max. magnification: 0.28m (0.92ft) / 1:5.9 similar to the 0.29m (0.95ft) / 1:5.5 of the Otus. With manual focus I was able to get a bit better magnification of 1:5.4 on the new Nikon. That’s not much but about standard in this lens-class. You only have 12cm of working distance (with lens hood detached). A magnification of 1:10 is achieved at around 0.42m distance with 26cm working distance. 
Filter-thread: 77mm, the widely used professional standard. The Otus needs 95mm filters. [+]
Image Stabilization: No, same with the Otus. 
Auto Focus: HSM (Hyper Sonic Motor), so it also works on camera bodies which don’t have an AF-drive built in like Nikon’s D3x00/5×00. Manual-focus override is by simply turning the focus ring. The Otus is manual focus only. [+]
Covers full frame/FX or smaller = very good. As does the Otus. [+]
Price: around 2000 USD / 2400 EUR (incl. 19% VAT), which is pretty expensive. Nikon’s 24/1.4G and 35/1.4G can be had for around 1800 EUR. But to put the price of the new Nikon in perspective: The Otus currently sells at around 4500 EUR. [-]
Comes with a flexible lens pouch (no padding, no strap), the lens hood is included, reversible for transport, and the lens-caps are standard Nikon’s. The lens hood throws a shadow at the bottom of the image when you use the onboard flash of the D810. Without lens hood there is no shadow. 
Distance information is relayed to the camera, so the Nikon body can do all the advanced exposure-related stuff with this lens. The Otus cannot do that. [+]
Aperture ring: no. The Zeiss Otus has one. 
Sealing: A rubber grommet at the lens-mount and more in the lens barrel. [+]
The score in the “features-department” is 1[-]/6/6[+]. This is pretty good with the price the only real down-side.
- There is only one other 28mm f1.4 lens available for Nikon (and Canon) users: The 28/1.4 Otus from Zeiss. It is an excellent lens but even bigger, heavier, and more expensive than the Nikon. And it has one major drawback: it’s manual focus only! The lens earned a Highly Recommended in my Zeiss 28/1.4 Otus review for its outstanding optical performance.
- Nikon has the 28/1.8G as a smaller, lighter, and at 650 EUR much cheaper alternative. For that price you lose two thirds of a stop in focal ratio. See my Nikon 28/1.8G review where the lens got a recommendation.
- Other than that you either have to look for a 24/1.4 or a 35/1.4 lens. Both lens types are on offer from Nikon or Sigma amongst others. See my Nikon 24/1.4G review, Nikon 35/1.4G review, Sigma 24/1.4 Art review, Sigma 35/1.4 Art review.
Focus accuracy and repeatability is critical to consistently produce sharp shots. Repeatability (the accuracy of focus on the same subject after repeated focus-acquisition) of this lens is very good (measured 98.9% in Reikan FoCal) with no outliers over a series of 40 shots under strictly controlled test conditions. And there is only a small performance variation whether the lens focuses from infinity or from a closer distance. At f1.4 the lens requires some exact focus fine-tuning in camera especially at a distance around 1m where depth of field is just a few cm. Even 3 points of fine-tuning (on a scale from -20 to +20) can make the difference between hit or miss at f1.4. So better take the time to adjust the AF of your camera accordingly.
The lens focuses with no hunting in around 0.6 sec from infinity to 0.4m, which is fast. The focus ring has no slack/play between its movement and the focus-action and a throw of 135 degrees which is good for manual focus wide open. Its rubberized surface is 21mm wide and can be turned with one finger although it moves not as easy as from the Nikon 35/1.4G or 24/1.4G.
AF-operation is very quiet from the outside, and if you record video with the built-in microphone the AF-drive produces a slight hiss and only faint clicks at the start or stop of focus-movements.
As you pull focus, you’ll notice some focus breathing: the image becomes more magnified at closer focusing distances. When I adjusted the focus from infinity to 0.40m, I measured a 4% increase in magnification which is pretty low and should not prove too distracting when shooting video.
