Today, Leica has released a firmware update for the recently released Leica Q3. Looks like Leica was able to make some meaningful processing optimizations under the hood, resulting in faster wired data transfer speed to FOTOS, ability to render a continuous preview in continuous shooting modes, a significant reduction in startup time and better quality live view exposure simulation. Other notable changes include assigning the default video format to 4K30 in order to guarantee playback in Leica FOTOS and an automatic switch from AFc to AFs in low light conditions to prioritize focus accuracy. Overall, this should be a welcome update for Leica Q3 owners, making for a more polished user experience.

Enhancements and Improvements

  • The data transfer speed via the Leica FOTOS cable was significantly improved
  • New default setting for video format (MP4, 4K, 29.97fps/L-GOP/100Mbps/4:2:0-8bit SD & HDMI/H.264): Ensuring that recorded videos can be downloaded via Leica FOTOS to the mobile device for playback.
  • Improved rendering behavior for series of shots: This facilitates a continuous preview for Continuous – 2 fps / 14 bit / AF and Continuous – 4fps/14bit/AF.
  • Automatic switchover from AFc to AFs in low light conditions, the display will now be in Live View
  • Significant improvement of startup times
  • The rendering quality in Live View when tapping the shutter button (1st pressure point) was significantly improved
  • Bugfixes in the firmware

    Here’s to hoping they fix the battery drain while the camera is off – some say it’s related to Bluetooth, some say it’s related to the wireless charging grip, all I know is it should have never have launched with such an egregious issue.
