I think we have a pretty clear idea about what’s coming next from Panasonic and Olympus. So let’s make a roadmap table:
Olympus will launch the 300mm f/4.0 PRO lens with in lens stabilization
Panasonic will launch the Leica 100-400mm f/4.0-6.3 lens.
Olympus will launch a new kind of PEN camera with built-in EVF
Panasonic will launch a new GM7 4K camera
Both companies may also show early prototypes of their new fast prime lenses.
Panasonic will launch the new GH5 cameras (maybe with 8k?)
Olympus will launch the E-M1II
Of course there will be some more stuff that we don’t know about yet. Maybe a GX8, another new PEN and some other premium glas.
