Dear all, especially @Hermann-SW,
I'm happy to report that we bought the new ArduCAM 1.58MP IMX296 Color Global Shutter Camera and it is a functional plug-n-play replacement for the RPi GS Cam, though I'm not able to provide direct quality comparison. In our application, we are quite space constrained and were using M12 lens anyway, so we are quite excited with this news.
