I have reported about Canon Japan working on their full frame, EF mount, mirrorless camera for over a year now. There are a few working prototypes floating around in their labs. They have not finalized on a marketable model but I will not be surprised we will have an announcement at year's end or early 2019 from Canon and Nikon. Sony's free ride with their A7 and A9 series of full frame mirrorless cameras will come to a crashing end.
In a recent speech given by Canon's CEO, Mr. Fujio Mitarai, he made the following comments :
"Within existing businesses, there are market areas that are growing, such as mirrorless in cameras,” Mitarai says. “In these segments, by launching differentiated products that only we can provide, we will stimulate the market, grow our sales, and secure additional market share.
For example, in our core camera business, in addition to our overwhelming share of the DSLR market, we will go on the offensive and work to expand our sales in the mirrorless camera market, which is exhibiting remarkable growth . . . . This will allow us to reach our goal of 50% market share of the entire interchangeable-lens camera market."
Earlier this month at the CP+ Show in Japan, Sony Camera's General Manager, Mr. Kenji Tanaka made the following comments :
"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."
