LR admin · Aug 31, 2023

Today Leica released new firmware updates for three Leica SL cameras:

Additional information is available on Reddotforum:

SL2 / SL2-S version 5.2.0 Improvements

BP-SCL6 Support: The biggest feature in the new firmware is official support of the latest BP-SCL6 battery. Introduced with the Q3, the new BP-SCL6 offers 18% greater capacity at 2200mAh than the original BP-SCL4. While the newer battery seemed to work fine in SL2 cameras prior to the update, official support means more accurate battery life indication and greater stability.
Limitation for Higher Current Consumption Lenses Removed
New M Lenses 6-Bit Code Support: With more 6-bit codes and lens correction profiles, the SL2 and SL2-S will work with all the latest M lens offerings from Leica, including the recent 50mm Summilux-M ASPH II, which was introduced after the last firmware update.
Misc Bug Fixes

SL (Typ 601) version 4.0 Improvements

Profoto Remote Flash Control Support: Already present on the newer SL2 and SL2-S, the SL601 can now natively use Profoto remote flash systems. Nice to see Leica continuing to add functionality to previous generation cameras.
New M Lenses 6-Bit Code Support: The SL601 gets the same additional M lens support as the SL2 and SL2-S
