Review Nikon 50mm 1.8G AF-S Nikkor (N FF)
The Nikon AF-S 50mm 1.8G is is a fast and compact FX prime lens that entered the market in 2011 as a replacement for the Nikon 50 mm 1.8D. We've tested this lens earlier, using a Nikon D700 with a 12 megapixel sensor. With a Nikon D800E, this lens really can show it's impressive resoluton performance.
Review Nikon 50mm 1.8G AF-S Nikkor @ Nikon D800E
Construction and autofocus
The Nikon is lightweight and feels less solid than, say, the Nikon 105 mm 2.8 Macro. If you are used to kit lenses designed for APS-C cameras though, you do experience this 50 mm as a solid lens. The focus ring turns very smoothly and if there is a filter on the lens, it does not rotate. Very handy when using a polarizing filter. The Nikon is supplied including the lens hood, which is firmly attached.
The new Nikon 50mm 1.8G is an AF-S type, which means an internal AF drive. This drive is very smooth; focusing with a Nikon D700 takes as long as with a D5100: 0.2 seconds with a focus stroke of 15 meters to 1.5 meters. I expected less noise from the AF, but hunting in low light is rarely observed.
When you don't corect vignetting usig the standard lens profiles in Lightroom or Photoshop, you will sometimes encounter visible vignetting. The Nikon D800E corrects vignetting for you in the jpg files. At f/1.8 the vignetting in jpg files is half the vignetting in RAW files.
The distortion amount is a fraction over 1%. For a not so difficult to design and fabricate lens as a 50 mm 1.8, we expected a slightly lower value. In practice, you will have to address the distortion with software.
The lens shows moderate barrel distortions at around 1.1%. This is more than you'd expect from a fix focal lens. However, this is actually a typical amount of distortion for fast standard primes and unless you shoot subjects with straight lines near the image borders it's usually not field-relevant.
If you like to limit the depth of field, as photographic style device, you choose a lens with a wide aperture and you choose a camera with great image sensor. But that is no guarantee that blurred parts on the photo are also nicely blurry displayed. The Nikon 50 mm 1.8G, with its 7 round aperture blades, does not disappoint us; the bokeh of this lens is absolutely beautiful.
|The Nikon 50 mm 1.8G has little with flare or ghosting at an open light source. We've founf the ghost you see in the 100% crop to the right in an image we shot with heavy backlight.
The Nikon 50mm f/1.8G lens is a very sharp lens: even using the 36 megapixel Nikon D800E this lens performs better than the much more expensive Nikon 50mm 1.4G lens. The difference in center sharpness of the Nikon 50mm 1.8G at full aperture or f/5.6, is actually quite small. The sharpness at the edges and in the corners is visibly better if you stop down two stops. The optimum is around f/4- f/5.6, but f / 8 and f/11 are almost equivalent in terms of sharpness across the entire image field.
The chromatic aberration, both lateral and longitudinal (color bokeh), is low. Also positive is that the difference between the best and worst values is low. Color bokeh is a common issue with relatively fast glass. It can be visible as halos of different colors in out-of-focus areas - magenta (red + blue) in front of the focus point and green beyond.
Typical for most fast primes, the Nikkor shows noticeable bokeh fringing, but not much, at large aperture settings, which can of course be reduced by stopping down.
