Got my hands on the Nikkor 200mm f/2 this past weekend. What an epic lens. I don't have much to say other than wait for the next two blog posts for photos taken with this lens. It's definitely on the heavy side, coming in at 10lbs with the D850. The weight is good especially being a 200mm prime to hold steady. The speed of the autofocus and sharpness is incredible.
