>>3809442I have one. It is a neat concept, but the sensor wasn't really all that cutting edge when it was released, and is ridiculously outdated now. There are actually a few phone cases that took it natively when it was released, though nothing for modern phones.
You'd be better off getting a newer e-mount body.
