SIGMA is expanding its popular Contemporary lens lineup with three new additions for Leica L- and Sony E-Mounts. Two of the models are designed for use with full-frame sensors, with the third meant for APS-C crop sensors. All three of these lenses will be available later in April 2023, with pre-orders open now. You’ll find a new 17mm f/4 lens accompanied by the 50mm f/2 for the full-frame side of things and a 23mm f/1.4, a 35mm equivalent lens on a crop sensor.
