New Leica SL firmware improves the L-Log mode

The Leica SL turns a few heads when it was announced a couple of months ago, most notably for videographers. For the first time Leica has produced a camera with 4K output and some other serious video features, including a PL mount adapter so Leica’s cinema lenses can be used with it.

However, one feature that didn’t go down too well with videographers was the the Log mode, which set the black point far to high, making it very difficult to colour grade the footage in post production. Even when using adavced software such as Blackmagic Da Vinci Resolve. The problem was first noted by Andrew Reid on his EOSHD website, and has since been spotted by many others.

The new 1.2 version firmware address the issue with the L-Log mode

‘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’.

The other updates via this firmware are ‘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’ and ‘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.’
