well that stinks. I got the metabones. In the end I'll end up only adapting my sigma stuff. ugh.
Also... only way to really do the swap would be to sell the 200/2. This would be buying the A7R3 and the A73 (for the wife) but really we could then swap around bodies as needed.
Here is my sell list vs buy list. I planned on keeping the 35 and 85 arts and pick up a 135 to replace my 200/2....
Basically I'm out just buying the 135... this is assuming I return the metabones and use the MC-11
Don't get too excited about the videos, I only had my 135 Art with me and it seemed to perform the same with both adapters, actually the metabones seemed a tad better at focusing speed
