In my podcast review of the Sony a7R IV, I commented that the images it captures at ISO 32000 and 64000 are quite useable for certain subjects. I thought you might want to see what I was referring to.

These photos were recorded in very low light conditions with the Sony a7R IV with G-Master 24-70mm f/2.8 zoom at ISO 32000 in RAW. I processed the files in Capture One Pro 12 (latest build) and exported sampled-down pictures as Jpegs for publishing.

The shoot location is the Blind Scream haunted house in Santa Rosa, CA. The sets and actors there are top notch. It's worth a visit if you're in town. If that's not doable, here's how the Sony a7R IV renders the scenes.
