Leica has confirmed on Facebook what a LR reader already reported over the weekend:
“We have put the new D-Lux 4 firmware update since there still was a small mistake in the French menu. All other languages will not have the problem. We are presently working on a new, perfect version. Please excuse the inconvenience.”
The bug in the v2.10 firmware has been described as:
“when you select french language and choose the Lens Resume setting, everything freezes”.
I will update my D-Lux 4 tonight and will report more details on that bug. Other languages should be working fine.
