AHHHH Sounds like I will be sticking with just the MC-11.
I somehow thought with the Metabones I would get farther to the edge focusing . With the MC-11 it seems once I get off center it wont track anymore. I guess that is not the case?
I don't think the Metabones vs the MC-11 adapter is the limiting factor. I don't think the Metabones would be any different, with the same lens and the same camera body. But I don't do a lot of tracking photography, so you may need to hear from someone who does.
I think it rather depends a lot on which camera you are using, and also which lenses. The A73 has AF sensors farther out toward the edges, so you will get better tracking going out toward the edges. The A7r3 and A7r2 have more centered AF sensors, so you can't get AF as close to the edges.
I have also found that my Canon lenses seem to vary. The Canon 24mm f/1.4 II, 35mm f/1.4, the 35mm f/2 IS, the 50mm f/1.2L, and the 85mm f/1.2L II all autofocus well for me with the MC-11, a bit better on the A73 than on the A7r3, but very acceptably on the latter. However, the 135mm f/2 focuses well only with the more central focusing points on either camera. If I try to use a focus point toward the edges, it hunts unacceptably. This might be (though I really don't know) because it is a much older lens design (though my copy is recently made) with older firmware algorithms.
