It looks like Sigma’s president Kazuto Yamaki is unable to decide the sweet time to start producing full frame FE lenses for Sony E-mount. Yes, same thing he said again as he did in March of previous year that “we will make lenses for Sony FE-Mount”. Also, to accomplish this promise the honorable president of Sigma himself bought a Sony A7R II camera to understand the performance and capabilities of the Sony hybrids. Actually, he stated this in an interview with Focus numerique.
Here is the Google translation:
The future of EF mount is beaming. So yes we will come out of EF mount objectives in the future. I personally bought a A7R II to understand the performance and capabilities of the Sony hybrids. I normally use our own devices with the Foveon sensor, but from time to time I buy new innovative devices ( “game changing cameras”). Just a few years I had purchased a Canon EOS 5D
And we hope Sigma will soon begin their lens development work for Sony FE-mount cameras
