Title: Need driver for Logitech webcam with Carl Zeiss Tessar 2.0/3.7 lens
Body:
I have an older Logitech webcam that features a Carl Zeiss Tessar 2.0/3.7 lens – I believe this is the Logitech QuickCam Pro 9000 or similar model. I’m looking for a compatible driver for Windows 10/11 (or specify your OS).
The official Logitech support site lists legacy software like “Logitech Webcam Software” or “Logitech QuickCam Software.” I’ve tried the generic drivers but still have issues (e.g., no video, focus problems, or missing controls).
Does anyone have a working driver package or know the correct driver name for this specific lens model? Thank you.
Search for:
Logitech QuickCam Pro 9000 driver
Logitech Webcam Software 2.50 or later
Logitech HD Webcam C910 driver (some shared chipsets)

Note: The lens marking “Carl Zeiss Tessar 2.0/3.7” indicates an f/2.0 aperture and 3.7mm focal length – hardware specification, not the driver name. The correct driver is usually Logitech QuickCam Driver Package or Logitech Webcam Software.
If you meant something else (e.g., you need a driver download page description or a safety disclaimer), let me know and I’ll refine the draft.
