Leica is rumored to announce a new 100-400mm lens for L-mount. The lens will be made in Japan, but I was told that it is not a direct rebrand of the Sigma version and will incorporate some elements/features designed by Leica. The price is expected to be around 2,500 $/€. The official announcement should be in Q1 of 2023.
Leica is also rumored to announce their first Leica branded 1.4x teleconverter for L-mount that is going to be priced around 800 $/€ (see the Sigma L-mount teleconverters). Expected announcement: Q1 of 2023. A second 2.0x teleconverter is expected later in 2023.
