Show HN: Tamron Lens Utility Alternative on Linux (github.com)
schobi 3 hours ago [-]
Great result - it would be nice to learn how this could be used..

How would you connect a Tamron lens to a Linux machine? Is this with the external USB port or Bluetooth dongle? Or through the bayonet connector? A linx camera controlling it's lens?

Just for settings and firmware update? Or some imaging workflow? Can you give a practical example of Linux also controlling the camera?

New Tamron lenses have built-in usb-c port close to the lens mount. The utility just replicates what official Windows/Mac software does - not much, configuration of focus-by-wire, corrections, button functions.

Sounds weird to me to have this functionality on the lens in the first place.

Modern lenses are complex electronics now. They need to communicate with the camera about correction params, metadata, control algorithm for focusing and stabilization. Having a usbc port is a natural next step.

Lenses have energy budgets, responsiveness concerns and actuator/sensor pairings through embedded processing. Therefore they need firmware. Firmware goes out of date and has bugs and improvements. Having the ability to configure a lens beyond simply selecting firmware is an obvious second use of the required interface.
