Panasonic has announced the concept of their fullframe mirrorless cameras yesterday and there is an interesting line…
The cameras are nice, they look cool, they look smart and professional, that’s no question. We don’t know most of the specifications yet, but if you look at the text of some marketing material, you’ll notice a strange sentence:

It says
High precision, high speed shutter
• Highest flash synchro speed
Now that is very interesting. Among nowadays’ fullframe cameras even the fastest ones can provide only 1/250s sync speed, anything beyond that requires HSS, Hypersync or leaf-shutter.
We are very very interested of how Panasonic can push the boundaries of physical shutters with the Lumix S1R in 2019.
