As I already reported, the Sony product announcement at the IBC 2018 show yesterday was not photography related: Sony announced only two new camcorders (HXR-NX200 and HDC-3500). No new Sony a6500 replacement or a Sony a7sIII cameras were announced at the IBC show yesterday as some websites have suggested. There was also no Zeiss Batis 40mm f/2 CF FE lens announcement on September 10th as some websites have suggested... as I already reported as well...
Here is a list of questionable reports that can be found online about new products "rumored" to be announced for Photokina:
We have no specs, leaks or any other type of reliable information to indicate that any of the above products are real.
