There are too many SLR style full frame Mirrorless cameras out there and not enough rangefinder style.
My biggest hope for years now were that Sony would take the form factor of their a6xxx series cameras and make it full frame with a few extra upgrades; but we never got it. Then I was looking to both Canon and Nikon to do it. And they never did it. Surely I thought that Panasonic, with their history involving Leica, would be the ones. But alas, I was again disappointed. Like some of you, I fall into the camera of photographers who like the Olympus Pen F, the Fujifilm X Pro 2, and the Fujifilm GFX 50R more so than the SLR style camera bodies. To me, they’re more familiar. Perhaps like you, I was trained on Leicas. The feeling of a Hexar AF, a Contax G2, and a Mamiya 6 appealed to me more than some of the most prolific film cameras of all time.
