Sigma’s CEO Kazuto Yamaki has been interviewed by Imaging Resource. He said that there is a new delay in the Foveon sensor development caused by the worldwide chip shortage,. Their partner for the Foveon sensor development has to first focus on fixing their production limitations. There is also one more good news. When asked about the Foveon sensor having PDAF he answered:
In terms of the autofocus performance, the phase detection is the best solution. So I personally believe we need to implement phase detection AF, but we haven’t made a decision.
