The Nikkor AF-S 28mm f/1.8G is a wide angle lens designed for Nikon’s range of DX and full-frame FX-format DSLRs. Announced April 2012, it’s the larger aperture sibling to the venerable Nikkor AF 28mm f2.8D from 1994. It can also be considered a cheaper alternative to the AF-S 24mm f/1.4G and AF-S 35mm f/1.4G (see my Nikon 35mm f1.4G review for the performance of this high-end model).
With a line-up of three not too expensive f1.8 primes at 28mm, 50mm, and 85mm, Nikon seems to have completed the renovation of a set of FX-capable lenses that are considered the primary goal for people wanting large aperture primes at a reasonable price.
The 28mm focal length sits nicely in-between 24mm and 35mm as you can see in the following image where I’ve inserted the frames for the respective focal lengths. Thus an 28mm lens might be considered a more attractive complement to a 50mm prime than both the slightly wider and longer alternatives. 28mm offers a clearly wider angle of view: it captures around 56% more area of any given scene than a 35mm lens. Which also might be considered too close to the framing of a 50mm lens to be of interest to owners of the latter. But conversely a focal length of 28mm on an FX-body is not as “extreme” as a 24mm. Distortions at the borders of the frame are less pronounced and thus more acceptable. Meanwhile on a DX-body a 28mm lens is equivalent to 42mm and considered close to the ideal focal length that matches the diagonal of the sensor and thus produces “normal” looking images.
Interestingly Nikon has so far chosen not to produce an AF-S 24mm f/1.8G or an AF-S 35mm f/1.8G for the FX full-frame format (although of course there is the popular DX 35mm f/1.8G lens for cropped bodies). That may have to do with economical reasons, but Nikon might have fared better had it given its DX 35/1.8G a proper FX image circle and complemented it with a 24/1.8G, because a 28mm prime might just be too long for some and too short for others. But again, such a move might have brought the risk of jeopardizing sales of its 24/1.4G and 35/1.4G lenses.
So far Nikon’s new f1.8 designs (the 50/1.8G and the 85/1.8G) have proven to be sharp and contrasty rendering neutral colors (see my Nikon 50mm f1.8G review and Nikon 85mm f1.8G review). This puts pretty high expectations on the newcomer. In this review I’ll have a look at Nikon’s newest 28mm f1.8G prime, and find out whether the lens lives up to the expectations.
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.
Size (diam. x length): 73 x 81 mm (2.9 x 3.2 in.). It’s slim but pretty long – especially compared to the Nikon 28/2.8D at only 45 mm (1.8 in.) length 
Weight: 330 g (11.6 oz) = pretty light-weight, although the 28/2.8D is only 205 g (7.2 oz.). But the lenses from Sigma and Zeiss are both much heavier at around 500 g. 
Optics: 11 elements in 9 groups. More than the 28/2.8D with 6 lenses in 6 groups but still only a small amount of glass compared to zooms that tend to have something like 21/16. That bodes well for contrast and flare-resistance. Plus Nikon used Nano-coating on this lens and the cross-section does show two aspherical elements. [+]
Closest focus distance/max. magnification: 0.25 m (0.82 ft.) / 1:4.5. This is close to what I often need in nature (1:3-1:5). [+]
Filter-thread: 67mm = a cheaper standard than with the larger pro-lenses [+]
IS: No = not really critical at such a short focal length, although Nikon’s own 24-120/4.0 has VR 
AF: AF-S with SWM (silent wave motor), so does work on D60/3×00/5×00-bodies, and there’s manual-focus override by turning the focus ring [+]
Covers full frame/FX or smaller = very good [+]
Price: around 700 EUR new (incl. 19% VAT) = not cheap! The old Nikon AF 28/2.8D is around 280 EUR now, the Sigma AF 28mm 1.8 EX DG Asp Macro can be had for 430 EUR and only the manual focus Zeiss ZF.2 Distagon T* 28mm 2.0 is more expensive at over 1000 EUR. 
Comes with a flexible lens pouch, lens-shade is included and revertible for transport, and the lens-caps are standard Nikon’s. 
Distance information is relayed to the camera, so the Nikon body can do all the advanced exposure-related stuff with this lens. But this is true for most alternatives too. [+]
Aperture ring = no, just like all Nikon G-lenses. 
Sealing: yes! A rubber grommet at the lens-mount. [+]
So the score in the “features-department” is 0[-]/6/7[+]. This lens ticks almost all important boxes, except perhaps a price below 500 EUR.
A 28mm lens may be a favorite for landscape shooters but they need corner-to-corner sharpness more than an f1.8 aperture. But the large aperture makes this lens also fit for fast street-/PJ-style shooting with an immersive in-the-middle-of-things perspective. A large aperture is also always good for isolating your subject from the background. But at 28mm focal length you have to be close to enjoy this effect.
Current 28mm primes include only three alternatives:
– The old Nikkor AF 28/2.8D
– Sigma AF 28mm 1.8 EX DG Asp Macro (meaning 1:2.9 max magnification)
– Zeiss ZF.2 Distagon T* 28mm 2.0 manual focus
But if you look at 24mm (-14% focal length/magnification) or 35mm (+25% focal length/magnification) lenses there are more alternatives to chose from.
