Yes! I am switching from Canon. I have older gear at home and will be upgrading that, but will still use Canon gear at work for the foreseeable future. I rented the A7rII this summer when I went on vacation in the Rockies and this new camera addresses nearly every single issue I had with that camera. Glad I waited, and even if it's not perfect, the image quality will be amazing. The inexpensive 28mm f/2.0 and 85mm f/1.8 rendered beautiful, sharp images on the A7rII and editing them on my 10.5" iPad Pro (and carrying it all in my compact Tenba mirrorless messenger bag) while traveling was a dream.
I couldn't believe that they priced it that low relative to the A9 when it has many of it's features. On paper it looks almost too perfect, aside from the lack of 60fps 4K. Fortunately I don't record a lot of video and when I do it will probably be with my iPhone X which can do 60fps 4K. But it can also do 24fps which is nice for the cinematic look that I enjoy and it also does HDR. The only remaining issue that will probably be a problem for me is dust. Mirrorless cameras my nature seem to collect more dust inside since they don't have a mirror blocking the sensor when swapping lenses. I'll need to be blowing it out with my Giottos rocket blaster frequently when changing lenses since I've moved to mostly using primes and love shooting outdoors.
I'm glad that companies like Sony are able to push innovation in the professional sector while Apple eats up the low end of the market. It's good to keep professionals several steps ahead of the general population, but I have to wonder how long before smartphones are able to mostly catch up by faking everything with ML and advanced image processing. Even hardware advancements like the one in this article will help make tiny sensors and lenses much more capable.
