How to install the update
- Via Leica FOTOS App: Ensure your camera battery is fully charged. Pair the camera with the Leica FOTOS App, check for available updates, and follow on‑screen instructions to install.
- Via SD card: Download the correct firmware file for your camera from the Leica site. Copy the file to a freshly formatted SD card. Insert the card, power on the camera, and start the firmware update from the camera’s menu. Do not power off during the process.
- Post‑update checks: Restart the camera, verify firmware version, and review AF and UI settings to confirm improvements.
Should you update?
Yes—especially SL3/SL3‑S users and Q3 shooters who value speed, AF precision, and streamlined UI. The SL3’s new Multishot mode alone makes this a must‑install for detail‑critical work. Q3 users benefit from a cleaner, faster interface and improved AF. If you rely on collaborative workflows, the direct Frame.io connection on SL3/SL3‑S is a significant upgrade. As always, back up settings and prepare a fully charged battery before updating.
