Sony did not announce a new a7S III mirrorless camera or an a6500 replacement at Photokina. In a recent interview with Cinema5D, Sony Senior Manager Yutaka Iwatsuki who is responsible for product planning said that the Sony a7S III will go beyond customers’ expectations, but it still requires a lot of work:
They are responding to what their customers want and not what the competition is doing
Wouldn’t give a firm answer about 8k
Still a lot of things to do for full frame so they do not have a plan for medium format
Also, APS-C has things to do
Can’t comment on future products
Video and cinematography are very important to Sony Cameras
It’s also interesting that Sony is making a big effort to mention APS-C every time they mention full frame. Maybe we will see a serious APS-C camera from them soon along with some glass. They really should have announced it at Photokina though.
