I bought a Sony A7R II in late 2016 with the cheap 50mm Sony has. Thought I'd like it, but I ended up hating it, so I got rid of it. Then last year I did the same with buying the A7R II again, except this time, used it my Canon 24-70 with the Metabones V adapter. Kept it a bit longer this time but still somewhat hated it. The lack of lens profiling made it annoying to use, and the autofocus was slow, the battery life sucks. I ended up getting rid of it for the 5D4.
In comes the A7 III. I'm now thinking about dropping Canon for the new release. Again, I'd be adapting my current Canon lineup. Now that battery life is a bit more competitive, and the *supposedly* the autofocus is faster with adapted lenses, I'm hoping it'll be something I stick with for a period of time. However, having previously gone from a 5DIII to a 5DIV, I'm not sure how I'll feel going back down to 5DIII resolution. I'm spoiled by the 5DIV in that regard. I owned a 5DSR somewhere inbetween, which really spoiled me.
Another camera on my plate of potential choices is the A7R III. I'm not sure what the difference is between the A7III and A7RIII aside from resolution, so that's something I'm looking to narrow down on. Versatility is a priority for me because I do lots of different types of shooting. I prefer portraiture, but my camera ends up being used for everything, landscapes included. I've heard the A7RIII viewfinder is better than the A7III, along with the display screen. That's important because in the past year, despite my young age, I've needed to start wearing glasses and it seems my eyesight is becoming progressively worse.
I'd like some input from you guys!
