Thing is...
Early 2019 could mean June 2019, that’s 9 months from now. Sony can announce the A9mk2 by then with the same 9 month lead time for it to be release the following March which makes it exactly 3 years since the A9 came out.
CAF? Nooooooooo
It says 3 axis tilt, not flipped screen tilt.
It doesn’t mention full sensor 4K/60.
Any Eye-Af?
Leica lenses I can rule out completely, it’s way too expensive.
Sigma can adapt their Art lenses to it but it should be just like adapting it to the Sony FE.
Sensor unknown.
Battery life unknown.
FPS unknown.
AF unknown.
Plus it’s a 1st generation camera, so I don’t expect it to be amazing amazing. It should be good but I don’t think it will spank the Sony...not before Sony can spank right back around that time
Ps too many cooks and all that is also a concern.
