The good news is that it is an excellent sensor:
Agreed: this sensor and others of its size can offer a nice balance of performance far better than phone in a camera far more portable than any SLR, so with the right execution, maybe systems based on 1" could eventually outsell ones based on 4/3" or APS-C, by hitting the sweet spot for a greater number of customers.
But these days it seems that the key to a system's success is not so much the sensors (which are generally so good and give images of such high definition that they do not generate much differentiation between brands for the needs of most camera customers) as it is details in the execution, like:
- appropriate lens choices
- reliable, fast and flexible auto-focus,
- making it easy to use the camera and the photos in the ways that a large number of today's camera customers want to.
For now, both Nikon and Sony seem to be executing a lot better in this young 1" format sector.
