I just got this on my A7RV and I thought it was "pretty good" (especially considering the price). If you're not a pixel peeper, it does perfectly fine. I didn't want to spend a lot of $$$ since 50mm isn't really my thing and I have zoom lenses that cover 50mm, but I wanted a compact cheap lens to carry around. The autofocus is really bad compared to my other lenses, but it's still workable.

Yes the AF motor is pretty bad, but as you said, you can work it out
