Thanks John, Andrew and Akira for commenting.
John, the lens is the 50mm f/1.2 S, which arrived at my home yesterday morning. I tried it right away and was impressed by what the pictures looked like. I have the 50mm f/1.8 S and while it is a clinically sharp lens, I have never been able to take good pictures with it - my bad I guess. I was impressed by what Frank has done with the 50mm f/1.2 S and it sparked a desire to get the lens. The order was a month and a half on backorder from Nikon but it was worth the wait. It is the first 50mm lens in my lifetime that has really rocked my boat.
I will probably sell the 50mm f/1.8 S and another lens or two to offset the cost, but I'm keeping the f/1.2.
