I'm confident the new system will be every bit a performer in capable hands, as it will surely disappoint those less involved in actually producing images or, at the very least, acquiring the necessary skill to that end. Hoped for (or truly needed?) features might be absent first offerings and later adopted in future models as demanded. There are already enough blog-postings eschewing certain "dials", icons or absent buttons, relegating the new camera, or cameras, beneath the dignity of certain erstwhile experts. The rest of us will come to know through demonstration, practical use and trusted opinions if this is "the new brush" needed to better color our world. I still own a Nikon F. And barring any personal hardship, always will. One day I will own a mirror-less, "FX" frame camera. I suspect strongly, it will be a Nikon.
