Modified Zenitar-1S 85mm f/1.4
I was once interested in the following question: how will the aperture with a smooth change in permeability affect the images? I didn't have a filter with a circular gradient. I had to make a hole in a piece of felt and fluff its edges. And it turned out what's in the picture: on the right is the original state, on the left is the modified one.
An example of images with this lens with a modified aperture:

As a result of the modification:
1. The sharpness of the lens has increased slightly, as the equivalent aperture has become ~ f/2 (instead of f/1.4).
2. There is a glow of bright areas in the image.
3. The lens pattern has acquired a new character.
