A few weeks ago I already reported that shortly after the Leica SL3 camera announcement, there will be another M-mount lens announcement. I now believe the upcoming lens will be a new Leica Summilux-M 35mm f/1.4 Steel Rim black paint reissue version. The official announcement is rumored for or around March 21st, 2024. The price tag is expected to be around €9,980. This new lens will be a limited production run (only 200 or 250 pieces worldwide). Stay tuned for more details.
Update: the lens could be black anodized.
