I can't speak for iND, but one reason that I want it is bokeh. The 200mm f/1.8 is soft because it has intentionally undercorrected spherical aberration, which greatly enhances bokeh at the cost of some sharpness, similar to the 50mm f/1.2.

How on earth do you find all of this out? I've heard of "connections", but wow.

Easy. I read it on the internet, so it must be true. [] I saw a star test of the 200mm f/1.8 (I can't find it now), and the Point Spread looked like negative spherical aberration. I learned that such aberrations enhance bokeh when I was researching the 50mm f/1.2.
