Luvwine -- Looks like a great copy of the CV! Thanks for the comparisons, and looking forward to more of your shots with this lens.
On a different note: it looks to me like something is wrong with your Loxia 50, if it wasn't simply mis-focused. Mine is much sharper than that, and not so much CA fringing on high contrast edges. You might want to look at that lens' performance more closely.
Also, with regard to the IBIS settings: simply go the next lowest setting (60mm) to get best performance. I really learned a lesson when I set the telephoto zoom focal length too high, the camera over-corrected and made the images blurry, but under-corrected the images were sharp. On zooms, I choose at or just above the lowest focal length, such as setting a 70-200 to "85mm" in IBIS.

I will test the 50 for centering again. I hope it is okay as I just had to send in my Loxia 21 for warranty work, sigh. The 50 in my experience is really sharp in the center but needs stopping down to F4 or F5.6 or so to be really really sharp across the frame. Once stopped down, I liked it better than the FE55/1.8 (which I then sold). I am not at home now and don't have access to the files to look in detail, but from my brief look at the files, I thought the 50mm shots at 5.6 looked really good across the frame. Are you sure that at infinity wide open you cannot demonstrate any CA? This scene was a pretty tough test and even the "Apo" Leica did not pass wide open. Focus could have been off as I did the test fairly hurriedly, but I focused at F2 or F2.8 and did not change focus as I stopped down so that the F5.6 image was with the same focus as the wide open image. Also, don't judge the sharpness of the "scene" as for some reason I used the Loxia at F2 but used the CV at F5.6. The overall images that started the post were only meant to give an idea of where the subsequent crops came from.
