Sony interview at Optyczne: New A-mount and APS-C E-mount products are being developed
The Polish site Optyczne.pl (google translation here) interviewed Masaaki Oshima and Yann Salmon-Legagneur from Sony.
Here are a couple of interesting info:
1) Astro-tracer function (known from the Pentax K-3 II):
Sony says they are currently investigating how to apply it in future products.
2) Touchscreen:
Once Sony has reached a high level of quality of the touchscreen technology they will implement it on high end cameras too (The A5100 is already touchscreen).
3) RX with APS-C sensor:
There is yet no plan to make a RX camera with ASP-C sensor.
4) A6000 successor:
Sony said they are continuing to develop APS-C cameras. They cant of course comment about a possible release date of the A6xxx.
5) A-mount:
Just like APS-C E-mount also A-mount is being developed.
