Leica Q3 Firmware Update 4.0.0 - New UI, Better AF, Faster Startup

📥 Download my custom Leica Q3 or Q3 43 settings for free (firmware 4.0.0 needed): https://www.froschmayer.com/store. I also provided a PDF document outlining my assignment of buttons and wheels.

Leica has released firmware 4.0.0 for the Leica Q3 series, including the Q3, Q3 43, and Q3 Monochrom – and this is one of the most meaningful firmware updates Leica has delivered in the past months.

In this video, I walk you through what has changed, what actually matters in real-world use, and whether this update really makes the Q3 feel like a new camera.

We take a detailed look at the new Leica user interface, now aligned with the SL-series, improved AI-assisted autofocus, refined subject detection for humans and animals, faster startup times, better app connectivity, and important video improvements, including optimized L-Log color rendering and easier video profile handling. I also show how the update works via the Leica Photos app, what happens to user profiles, and why this firmware is a big step forward for Leica’s entire ecosystem.
Whether you are a Leica Q3 owner, a photographer considering switching from Sony, Canon, Nikon, or Fujifilm, or simply curious about how firmware can transform a camera, this video gives you a clear, honest, hands-on breakdown.
If you care about photography, storytelling, camera usability, and long-term systems, this update matters.
