Digital Suicide: 90% shots it will be set to infinity. So MF shouldn't a problem.
It's way better to set the distance at 1-3m rather than infinity as with whatever F number other than fully open you'll get DoF reaching infinity anyway.
Chop lens and AF, add a popular lens mount (*), peaking feature and and HDMI connector for an external display and it'll sell nicely as a specialized sensor + mount body for demanding pros and enthusiasts.
* Ideally one of the short flange distance mirrorless mounts, 2nd best EOS mount.
