Conclusion: For years, the popular and affordable 50mm/f1.8 was only available as an AF-D lens that cannot auto focus on today’s consumer DSLRs such as the earlier D40 to the current D3100 and D5100. This new AF-S version is a very welcome addition.
Summary: Overall, 50mm primes are rather unglamorous lenses that can look out-dated in a world where zooms are truly dominant. In fact they are often high performers despite their low prices and are therefore worthy of very serious consideration. There is little to fault in Nikon’s latest G-series 50mm lens.
Pros: Fantastic full-frame performance
Cons: Some chromatic aberration on DX-format sensor
Summary: Improving on a classic design is often a difficult task, but it is one in which Nikon has succeeded. The new 50mm f/1.8G lens adds some significant features such as a quiet Sonic Wave Motor, curved aperture blades, better image contrast and reduced chromatic aberrations.

Based on what I write in my lens reviews and/or comments on the forum you can easily assume I am not a man obsessed with extreme parameters or enthralled by the otherworldly vividness of f/1.2 or f/1.4 aperture; I...
Cons: image quality near the maximum aperture could have been at least a bit better,, noticeable coma in the corners of full frame,, distinct vignetting on full frame.

27 January 2009
Conclusion: The Nikkor AF-S 50mm f/1.8 G is a very solid performer that delivers very good to excellent sharpness across most of the FX frame. Typical for a fast prime there is some vignetting wide open as well as bokeh fringing. CAs and distortion are moderate.
