The Spanish site DSLRmagazine interviewed Mr. Yamaki the CEO from Sigma. And there are some additional new info:
- The SD Quattro cannot record video because the Foveon sensor has too much data to process.
- Yamaki said that you can record video with Foveon but you need “more resources” to make it work. And anyway video it’s not a priority yet for Sigma
- Autofocus us yet slow but it will be faster on the final production versions of the camera
- Also interesting: Sigma decided to make a SA mount mirrorless and not a SA mount DSLR because mirrorless has no micro-camera shaking.
