It’s not a case of Sony holding back their sensors, it’s just that Sony Digital Imaging business get around a 6 month exclusivity deal with Sony Semiconductors to use the latest sensor technology first.
Any 3rd party company can buy/source sensors off Sony Semiconductors providing they pay the price, Sony will even do custom designed sensors like they do for Fuji etc
Nikon have done well with Sony sourced sensors, managing to eeek better performance out of them than the ones in Sony’s own bodies
Sony are pushing out some great sensor technology, if you dig deeper into the history behind the Sony A9 project, the sensor was actually thought up over 3 years ago.
That’s some insight, imagine what Sony are working ok now that’ll be in bodies in the future.
Knowing Sony it’ll probably push the technology which they put in G Master lenses..... think Sony A9 with a 100mp sensor but even better AF, responsiveness, build, technology.
In the future all we would need to do is press the shutter button, the camera will do the rest, no stress, no effort..... no post processing... no workflow, just pure output direct to the client thus saving time and money.
Imagine doing a wedding and handing over the files straight out of the camera, that’s the future....... maybe
