Nikkor AF-S 50mm f/1.8G Review (by Thom Hogan – 08/2011)

What is it?
The Nikkor 50mm f/1.8G is slightly puzzling to Nikon users. It’s bigger and more expensive than the lower cost 50mm f/1.8D lens it replaces, but about the same size as the Nikkor 50mm f/1.4G (see side by side image, below). Thus, people are a bit confused about what problem it solves.

It solves one big problem: it gives D3100 and D5100 (and older similar DSLRs) users autofocus on a short telephoto (for DX) prime lens that is modest in price. The 50mm f/1.8D is a fine lens, but it won’t focus on the D40, D40x, D60, D3000, D3100, D5000, and D5100, so it really needed an update. On the other hand, the update produced a noticeably larger, heavier, and more expensive lens. Such is progress in the Nikon world.
