Nikon Nikkor AF-S 50mm f/1.8G review verdict

Having done almost 500 shots with the new lens I have a pretty good feeling for the overall performance of the new lens. So here's my summary.

Sharpness / contrast:

Contrast of this lens is excellent even wide open. Sharpness in the center is excellent too, but deteriorates visibly in the borders / corners unless you stop down to f4.0 or f5.6.


Focus accuracy and repeatability is quite critical with an f/1.8 lens where every inch of misfocus will immediately show up. That is one of the draw-backs when you use large aperture lenses. Repeatability (=accuracy of focus on the same subject after repeated focus-acquisition) is pretty good with only one outliers in ten shots and the AF-quality independent from the direction the focus was coming from (infinity or minimum focus distance). The 1.8G focuses clearly faster than the 1.4G, I'd guess about 1/3 faster. The focus ring of the 1.8G turns only about 90° from infinity to 45cm, the 1.4G turns about 180°. The short throw of the 1.8G is still good enough for manual focusing (in live-view), although the longer throw of the 1.4G makes that task much easier, and may also be preferred for movie focus-pulling. The only draw-back with the 50/1.8G: you can observe a slight focus shift between f2.0 and f2.8 - so for optimum focus quality of critical large aperture shots you should use live-view based focusing.


Longitudinal CA:

Well-controlled, nothing to worry about.

Other observations:

Again Nikon did not implement VRII with this lens - but that was to be expected after the 50/1.4G. This is a pity as any image stabilization would have extended the useful range of this lens even further. Compared to its bigger and pricier cousin, the 50/1.4G, the new lens has higher contrast and lower price as its advantages, so its price / performance ratio is excellent. So unless you really need the 2/3 larger aperture or the longer focusing throw, Nikon's newest baby should be your primary choice of a large aperture prime with the very useful focal length of 50mm - both for DX and FX shooters!
