Olympus will skip this years Photokina and not announce any new camera. But we know from very reliable sources that Olympus will announce a new high-end model camera in very early 2019 (probably in February).
This will be Olympus most advanced camera ever. Even more high-end than the E-M1II. What’s intriguing is that with Canon and Nikon FF mirrorless coming Olympus will have to really offer something exceptional to grab some attention!
