No disrespect to the project here, of course, but I'm wondering why there's no truly high-quality camera for Pis. I have the so-called "high-quality camera" and it still blows. I use it to monitor my 3-D printer with OctoPi, and that's about what it's good for.

There's Will Whang's boards - IMX585 [1] (16:9 1"-ish) and even IMX283 [2] (1") and even IMX294 [3] (Micro 4/3). But just those camera boards run $199 to $399, and released in "artisanal quantities"... so you have to pounce when Will restocks. Soho Enterprise has some IMX585 boards as well and I've seen some IMX585 MIPI CSI boards on aliexpress afair but never tried them

I'm experimenting with and have built a rangefinder-style camera [4], built around the IMX585 or IMX283 (the only boards I got my hands on) but using a CM5, this thing gets hot. It works though! Not too much bigger than my Leica Q. Haven't released anything yet but I tend to work on it and the model is in OnShape. Currently planning a complete screen-less redesign in FreeCAD... so that's _really_ different and slow, but I'm so over proprietary software :/

There's also the CinePi project using those sensors on a full-size Pi with a pretty active discord server.

By “high quality” you mean big sensor? 1” is possible - https://github.com/will127534/imx294-v4l2-driver and see OneInchEye based on the IMX283.

While many camera sensors use MIPI/CSI, you need enough lanes to transfer the data, the driver support in the kernel and other pipeline bits to get good images from the bayer. Almost all “real” cameras use ASICs or FPGAs to clock out the images. Additionally sensor companies are miserable to deal with in small volume and datasheets are under NDA. You’re much better off buying a camera from a machine vision company over USB3 or Ethernet, but you need one which properly enumerates as a video device (many do not). You can still do nice stuff like hardware sync/trigger from the Pi.

There's the Arducam IMX519 with 16 megapixels, Sony IMX 519 sensor
