It hasn't been since the release of the EOS 5D Mark III that we have seen this many emails and bits of information flood our inbox, and it's once again, extremely difficult to figure out what is real.
We're going to backtrack/reset what we think is happening, based on information from trusted sources. For the record, we're backtracking on things we've posted in recent weeks. I don't like it, but it happens.
We do know that at least one (and likely two) mirrorless cameras have hit certain certification agencies, thanks to Nokishita for always finding those. We do not remember a single time that a certified product didn't reach market, so rest assured, a full frame mirrorless camera is coming and according to the certification information, it'll be a full frame 30.4mp camera.
The elephant in the room is when are these cameras coming? We were told by a good source that we'd see an announcement in 2018 and even gave it a [CR3] rating. A couple of other sources I'd consider better have both cautioned me that they don't think an official announcement for a full frame mirrorless camera coming in 2018 at the time of writing this. Which would be bad news to say the least.
We've said it before and we think it's still very possible, that a “development” announcement might make some sense, especially if Nikon announces their new system for Photokina.
For now, we can confirm the EF-M 32mm f/1.4 STM and at least two “big white” lenses for Photokina. We also expect a new kit lens of some kind and there is the possibility of an unknown 5th lens coming in the next few months. What we do not have, is any sort of confirmation about what cameras will be announced for Photokina.
As for the full frame mirrorless, I'm going to tone down significantly what I report on the topic until I get information that I know to be legit, as to not unintentionally mislead the fine readers of this site. There may be a lot of truth in what has been reported, but it's pretty messy and unfocused.
We'll be better on this topic going forward.
