I do hope it's only 1 or 2 specific lenese.

How good is your optical theory?

Every lens is optically a compromise. Nikons newest generation of 1.8G lenses are spherically under compensated. There are several reason they could be doing this, let me name 2. Firstly, they are cheaper and easier to produce. Secondly and more importantly under compensating for spherical aberrations produces a smoother and creamier bokeh.

Your getting mixed up here. They're not under corrected for spherical aberrations the 35mm f1.8 has an Aspherical lens element.

That stops the softness and soft focus effect you can get on some lenses.
What they have is more distortion and under corrected CA
