Sony uses a particularly narrow lens mount. A wider aperture would be easier with Canon RF or Nikon Z mounts (Nikon Z having the widest throat diameter and the shortest flange distance among full frame cameras).

Because the e mount was designed for apsc that they brute forced into making compatible with full frame.

This thing is amazing. The kind of nasty extreme optics I love to see. Good stuff! The final images are pretty gorgeous. I'd love to shoot on this thing

What a great writeup! I really enjoyed reading the whole process and problem solving approach. This is why I come to Hacker news.

Are none of the images meant to load on mobile? I have to assume not, since without them I can't make sense of the article.

Wow this is pretty cool. I loved the images at the end!

what if I want the opposite effect?
I hate blur, how do I remove all of it?

Shoot with smaller sensors and step down your lens. The bigger the sensor the shallower the depth of field at given f-stop. For example when shooting with an APS-C camera at f2.8 you're going to get the same amount of light on the sensor but less background blur than when shooting on a "full frame" camera at the same f-stop. So if stepping down the lens is not an option because there's not enough light you can still get a little bit less background separation and blur when shooting with APS-C or MFT cameras.
Also the wider the lens the less background separation you get. 135mm lens at f2.8 is going to have razor thin depth of field while a wide angle 28mm is going to get way more in focus.
Also hyperfocal distance. With wide angle lenses you can get pretty much everything from few meters away all the way to infinity in focus at the same time. That's why (I think) all phone lenses are wide angle.

Shoot at f/64

There was a whole group of people who did this, apparently.

pinhole camera and an insane amount of light.
Or, multiple exposures and HDR.

Not sure how multiple exposures helps?
Smaller sensor, tighter aperture. So yes, more light or a more sensitive sensor.

They must mean by creating a composite image with multiple in focus areas? Otherwise I agree, I can't see anyway that multiple exposures would help, at least from some light reading on Wikipedia - https://en.wikipedia.org/wiki/Multiple_exposure
