Since Sony a7 III announced at CP+ Show 2018, there are more and more talk about full frame mirrorless cameras. According to recently interview with Sony Manager Kenji Tanaka, Sony Senior General Manager of the Digital Imaging Business Group, he said both Canon and Nikon will release their first full frame mirrorless cameras before CP+ Show 2019 in Japan, within one year.
From Sony Manager:
This is just my personal opinion, but I think that maybe by next year’s CP+ you’ll see full-frame mirrorless cameras from Canon and Nikon. I think [by then] they will be participating in this market.
Just look at our technologies, like eye focus. All of that data comes from the imaging sensor. In DSLRs, the data comes from separate sensors. The main imaging sensor is blanked out, 90% of the time by the mirror. The sensor is turned off. But the imaging sensor is very important. So if cameras are going to develop, and be more able to capture the moment, manufacturers have to develop mirrorless technologies. So within one year, I think.
