'
Currently in development, the prototype of the future K-mount APS-C DSLR will be presented during a European event tour that will stop in France from the 7th to the 9th of November. If its commercialization is planned for 2020, it will be possible to handle (literally: take in hand)
the camera on this occasion.'
If it's really possible to put one's hands on the camera, French people on this forum will report on the mysterious label on the bottom and, of course, the unlabelled button and its use.
Ejector rear LCD, beware, here we come!
