Yet another APS-C 56mm f/1.{4,8}:

Seems that the AF 50s are usually the path up the food chain.
The other day, I received a 7Artisans 50mm f/1.8 for testing ... but it wasn't compatible with my A7R V in certain configs.
So that's something to keep in mind.

The chinese manufacturers are simply flooding the market with options. Though conspiculously, there are no AF zooms just yet (Laowa has had a few UWA zooms, but they were stone age).
Also wondering how far are we from the lenses already released as MF to be reintroduced with the AF capabilities? Of course, not all of them, but some of the more popular ones, like - off the top of my head - Laowa's macros and their 15/2?

You can't just take any MF design and add an AF motor. AF lenses tend to have a more lightweight focus group. And QC has to be MUCH better because the focus group isn't quite as "tight".

Actually if silent and fast autofocus aren't priorities, and the customer is happy with a crappy autofocus, adding a micromotor that does nothing but move the focus ring can make any lens autofocus, it has its many drawbacks but it's surely feasible

Yeah, like I said -- not all of them. Not all of them are worth it, anyway.
But I hope the recent~ish MF renaissance is over again, and we'll be seeing predominantly AF lenses being introduced now, unless coming from super bargain bin makers or the deliberately retro-inclined players like Voigtländer.
