A trusted spruce confirmed that Sigma will announce the 17mm f/4, 50mm f/2 and 23mm f/1.4 on April 3. After those three lenses I expect Sigma to focus on more unique “one of a kind lenses” (my article about this here). There will be also a different version of the classic 70-20mm f/2.8 lens (my article about this here). I also got a first image of the new Sigma 23mm lens!
