I have been using a couple of systems concurrently and decided to go all in on a fuji system. The XT-20 is my body of choice. I picked it up locally with the 16-50 and immediately took it home to compare to my now very aged OMD-EM5. I splapped the 12-32 pancake on the olympus and the 16-50 on the Xt-20 and went shooting. My first surprise is that the 5 year old EM5 focuses faster consistently in almost any light. This is a noticeable difference. I was in single point af, with the smallest selectable point on both cameras, and I was looking for contrast while I was focusing. In lower light, the EM5 maintains its lead. This is surprising to me as I expected the 20 to be much better due to the phase detect af. My second surprise is that the IBIS of the EM5 is just so much better than the OIS of the 16-50. Really there is no comparison. I would say that IBIS is at least 2 stops better than the OIS. I found that I was having a much harder time getting sharp images with slow shutter speeds on the Fuji. I expected it to be worse, but this I believe was surprisingly worse. After getting them home, I began seriously looking at the image quality side by side. I will say that the xt-20 is a noticeable step up in quality from the 16 MP sensor both in resolution of detail and noise in higher ISO. There is no question that the resolution and quality of images is significantly better, even than my x100s. That was another shock. I had never realized that the lens on my X100s was quite soft, even at 5.6. I compared to the Em5 with the 12-32 pancake el-cheapo zoom and detail was better than the x100s. Not so with the Xt-20 and 16-50. So, I have no beef with the image quality of the XT-20. I am sure with nice lenses it will be leaps and bounds better than mu43. I am planning on getting the 18-50, the 35 or 23 f2, the 50 f2 and the xc50-230. Not a great amount by many standards, but I will be all in at least $2500 by the time I get extra batteries, filters, etc. That's a chunk of change, at least for me. So, the problem seems to be that the camera is still not as responsive in AF as my em5, OIS is worse than IBIS and only helps on lenses that have OIS. I love Fuji and have loved my X100s. I took only it to Italy in March and loved it, but felt too constricted by the slow AF and single focal length. I expected the AF to be better in the XT-20. I also wasn't expecting IBIS to have been that much of a crutch for me recently. I am not ready to give up the much better image quality for IBIS or slightly faster AF, so I am going to pick up either the 23 or 35 and see if I love it and if the Af is better. I just thought I would share my thoughts. I guess the deal for me is that I expected to be a little wowed by a brand new $1000 camera, and I'm kind of not. Is that normal?
