Severe rolling shutter artefacts are unsightly, and hard to detect and correct, but even imperceptible artefacts can interfere with the operation of machine vision algorithms.

Anyone have a picture side by side that demonstrates what the artefacts might appear like?

From the sensor datasheet it appears it can capture 60.3 frames per second. I don't see anything that provides a feel for its low light capabilities, although the pixel size seems to be about 17% larger than an IMX 327.

They should also do some sort of adapter/multiplexer board and dual camera bundle, for Pi3/Pi4, for quick entry to stereo vision without initially requiring compute module. That would be icing on the cake : )

Here is a good video comparing global shutter & rolling shutter[View:https://www.youtube.com/watch?v=I10PEyfGKNk:640:360]

This looks quite good!

I didn't understand why they fitted the older HQ camera with C-mount, it made no sense, considering it was a point-and-shoot camera type of sensor. This is a much better sensor for machine vision. Perhaps even astronomy (I'm not knowledgeable in that). When are they available? And I hope they are a reasonable price : )

Also finally they have a bit more sensible mounting system. The last one was pretty crazy, it seemed you couldn't fit it in an enclosure without exposing the PCB or applying pressure to it!
