Yongnuo is the third party maker for Nikon DSLRs. Few months ago, the Yongnuo announced Yongnuo AF-S 50mm F1.8 lens for about $50, but the problem is the plastic contact mount.
Today, Yongnuo improved the mount material of 50mm for Nikon and now they added metal mount instead of the plastic mount. The new Nikon 50mm lens will cost $82, however, this is still cheaper compared to Nikon AF-S FX NIKKOR 50mm f/1.8G Lens for $216.
