Leica have updated the firmware for the SL camera.
I would not read too much into such a quick update, that is what happens with pretty much all top end cameras, as manufacturers react to feedback, and access new features not ready at product launch.
Here we go with the details:
Leica announces firmware update 1.2 for Leica SL mirrorless camera system
New firmware optimises picture quality and improves handling
Leica Camera has announced a new firmware update – version 1.2 – for the Leica SL. Available to download now, registered owners can log in to the Leica owners’ area at https://owners.leica-camera.com to obtain the firmware, or bring their camera to a Leica Store or Leica Customer Service for a free update service.
The new firmware update 1.2 offers several fundamental improvements in picture quality and handling of the camera. These include, for instance, optimisation of picture quality at ISO values from 50 to 400, improvements to the image in the electronic viewfinder and greater flexibility when entering WLAN passwords.
When using Leica M and R lenses, the new firmware 1.2 enables the activation of a loupe (magnifying) function with the auto exposure lock button (AE Lock) to allow fast manual focusing. The firmware update also guarantees the correct indication of the R-Adapter-M and the R-Lens used in the EXIF data of image files.
In addition, the Leica Log Gamma curve (L-Log) for video has been improved to enable its use for in-camera 8-bit recording. The reduction of the offset now lets recordings appear considerably darker. Videos recorded with L-Log must be subsequently corrected with a gamma correction in an external video editing programme. The use of L-Log enables the greatest possible leeway for post-production colour grading of video recordings.
