Nikon offers its factory-refurbished Nikon AF-S Nikkor 50mm f/1.8G Lens, model no. 2199, for an in-cart price of $152.96 with free shipping. That's $6 under our mention from last summer and the best price we've seen for this lens. (It's also $64 under the lowest total price we could find for a new one.) It features seven lens elements in six groups, seven diaphragm blades, auto or manual focus, and 58mm screw-on filter size. A 90-day Nikon warranty applies.
