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
Excerpt: When it comes to great lenses it seems like innovation still happens at a glacial pace. Of course, one could just blame it on an age where new mobile phones are announced every 29 hours, but we digress. Good things come to those who wait and the Nikon 50mm f/1.8G AF-S ($220) is certainly just that.
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.
