Post a PIC of your latest purchase.

I’m not too familiar with Nikkor glass but B&H shows a couple in their accessory tab for that lens http://www.bhphotovideo.com/c/product/97413-USA/Nikon_1902_AF_Nikkor_50mm_f_1_4D.html

I think I would go with the Nikon HR-2 hood, it looks like that’s the recommended hood.
