The original GFX 100 seems like a great camera let down by some very questionable ergonomics. That portrait grip looks painful as does the tiny joystick. Hopefully Fuji addresses complaints in this new smaller body. An 80mm 1.7 combined with the great 110mm f2 would make a great system.
I ended up getting the Really Right Stuff L-Bracket, and I really have no problem with the 2nd grip, especially with this on.
I don't find the joystick to be a problem, no more so than the joystick on my older canon 5D3.
The original GFX100 IS big...but seems to be in the range of the Canon 1DX.....it too is large but folks still seem to sling it around.
I've not found the ergonomics to be a problem. But then again, I'm so used to my 5D3 where I Just turn the whole camera for portrait mode but keep my hands on those controls, that I do the same with the gfx...I don't change grips.....so, maybe that's it.
I'm spent on money, but I will be anxious to see what this new smaller form factor of the GFX100 offers. With it being smaller, I wonder if overheating, especially with video would be a concern?
