These things take time, at least Internet time
Contrary to Ray, I still have and love my Df. And ironically recently used a Fuji X-M1 for about 2 weeks and ended up not being happy with the RAW files. There was
something to them that I liked (a spatiality?) and B&W conversions were sweet, but there was something off about them that I cannot describe but could not get over. Of course, the X-M1 is at the low end of the spectrum, but it has the same sensor and the investment was minimal.
After many years with LCDs and EVFs (since my Canon 5D days) the Df OVF is pure joy to use, and the camera is so responsive (no lag at all). The files are a dream to work with and B&W conversions are amazingly fantastic - rich and pliable allowing a ton of flexibility in B&W processing approaches (high contrast, matter, etc). And I just like
using the camera. That said, the DoF can be hard to manage at times. But then again, I partly purchased it for its DoF control at the "shallow" end of the spectrum, and there it delivers.
I too worry about dust, but I rarely change lenses and I'm careful when I do.
