Leica releases new firmware for 6 cameras – including an important shutdown bug fix

Leica has rolled out a slew of firmware updates for a host of its cameras.

Firmware version 4.1.1 for the Leica Q3, Q3 43 and Q3 Monochrom forms the meat of the news, while smaller and seemingly less important updates have been rolled out for the Leica SL2 and SL2-S along with the D-Lux 8.

The company hasn't gone too in-depth with the details but, from what I can gather, the Q3 cameras get important fixes for bugs affecting auto-shutdown and remote app control, while the SL2 models and D-Lux 8 see their operational stability bolstered.

Leica firmware downloads

Here are the firmware downloads, all of which I’ll explain below:

Download firmware 4.1.1 (Leica Q3 / Q3 43 / Q3 Monochrom)

Download Firmware 1.9.0 (Leica D-Lux 8)

Download firmware 6.3.0 (Leica SL2 and Leica SL2-S)

It’s a good idea to hold off downloading the latest firmware for a few weeks. This should give enough time for any new issues to arise in community chatter, and for Leica to address them. Keep an eye on Digital Camera World and we'll let you know about any problems.

The Leica Q3 series brings high-end, full-frame compact digital cameras known for their solid build quality, 60MP sensor, and fixed prime lenses. Firmware 4.1.1 brings a trio of main updates for these cameras:

  • A fix for a bug preventing the camera from turning off automatically during wireless charging in “certain situations”. Leica hasn’t elaborated on what these are, but has confirmed the Q3 models now turn off automatically as soon as wireless charging is detected.
  • A fix for a bug causing the camera to unexpectedly switch to the default user profile in “certain situations”. Again, we don't know what the exact situations were, but if you were facing it, Leica says the issue is now resolved.
  • A fix for a bug causing Bluetooth connection failure between the Leica Fotos mobile app and a Q3 camera after a remote wake-up with certain Leica Looks (in-camera profiles) or AF mode settings applied. Leica hasn’t clarified which Looks or AF settings were triggering the error.

The Leica D-Lux 8 is a premium pocket-sized compact camera featuring a 17MP Micro Four Thirds sensor and a fast 24–75mm equivalent f/1.7–2.8 zoom lens.

Leica says that the latest firmware fixes existing “bugs in the firmware” without going into any details whatsoever. This is likely a routine firmware update to maintain stability.

Firmware 6.3.0 (Leica SL2 and Leica SL2-S)

The Leica SL2 and Leica SL2-S are full-frame mirrorless rigs sharing the same weather-sealed metal body and in-body image stabilization, but featuring different sensor resolution, speed, and video capabilities.

Leica hasn’t published release notes for firmware version 6.3.0, so we don’t actually know what the update entails. I’ll keep my eyes peeled for any new information and update this article accordingly.
