That's what a ND filter is for.....
Would a stereo camera fit the bill? Or is the 2 aperture idea more effective in one lens?
The Sony lens is a soft focus lens, not a super sharp lens.
Mamiya and others have done this for years.
They don't provide sharper or less sharp images, soft focus lenses treat the out of focus areas differently.
In the Mamiya 150SF for the RB for example, the glass is designed with spherical aberrations that affect the image when an f stop larger than f/8 is used. (At f/8 and smaller apertures the lens is "normal".) The lens originally came with 3 disks with many small holes around a normal aperture opening.
These disks allow a user to adjust to f/5, f/5.6, or f/6.3 while leaving the normal aperture control at f/4, the extra holes scattered around the main aperture allow the aberrations to "sneak in" around the edges.
This is one of my favorite lenses. This lens requires working differently, like stoping down to f/8 to focus and taking the lens apart to set aperture. It's effects are also strongest in the highlights.
...but, the samples look okay for me.

I am not a fanboy of SONY but just wondering what effect will bring on image quality when two or more apertures are used.
In the Mamiya 150SF for the RB for example said:Curious to look any sample pictures.
I have some rough negative scans:

As you might have experienced that squinting human eye can able to see outside world slightly sharper...
Had another thought here.
It isn't that you can see sharper, squinting actually degrades sharpness and clarity.
What it does do though is simplify the image, because extraneous detail is no longer "distracting" us, the "essence" remains/becomes more clear, not the image itself.
I do not know whether this is related to this discussion.
I am wondering why bellows in LF having ridges rather than smooth taper. Curious to know, how light propagates through the ridges.
Will adding an another aperture to an existing lens produces any sharper pictures, provided both apertures have same or different opening?

Just curious...
