In the next few weeks, SIGMA is rumoured to be announcing 4 new lenses for the Sony FE mount as well as their shared L mount with Panasonic and Leica.
SIGMA 35mm f/1.2 DG HSM
SIGMA 45mm f/2.8 DG HSM
SIGMA 12-24mm f/2.8 DG HSM
SIGMA 24-70mm f/2.8 DG HSM
It’s now rumoured that SIGMA will also make these lenses for Canon’s RF mount. It’s unknown if they will be announced alongside their Sony counterparts.
It’d be a good move for SIGMA to get in early on making lenses for the RF mount, as Canon’s RF lens lineup obviously needs some time to mature.
