Sigma has revealed that the long-awaited full-frame Foveon sensor will not likely be ready until next year. Originally announced in 2019, Sigma has already faced several delays due to the complex design of the sensor and how it can be mass-produced. 

Most sensors in the best mirrorless cameras and DSLRs use a Bayer filter array, where each photosite consists of a single light sensor in either red, blue or green to create a mosaic pattern. Sigma’s Foveon sensor uses a layered structure similar to film, where each photosite consists of three vertically stacked photodiodes, which results in a full-color readout at every individual site.
