> Get an A7-III, A7C for $2000, and install latest webcam drivers. Its colors and fidelity will blow Opal out of water, even without trying (both have 6K sensors, too). Colour, maybe, but fidelity absolutely not: over the USB connection, all Sony’s cameras deal in no larger than 1024×576 (citation: personal experience with an α6100, and https://support.d-imaging.sony.co.jp/app/webcam/en/instruction/ https://support.d-imaging.sony.co.jp/app/webcam/en/instructi... agrees this applies to all). You need to go HDMI to get 1080p or 4K, and then hopefully you’re on a desktop with a PCI-E capture card or something, because USB HDMI capture cards are a minefield with no perfect options (they all have problems with latency, compression, or colour, typically more than one of the three).
