Actually there is a Samyang 14mm AF lens.
Soon expected Laowa 15mm as well (hey have already almost perfect 12mm) But both will be manual focus. And not very cheap.
We have the very big hit coming as well: Sigma 14mm F/1.8 ART
Well, no the cheapest lens on the market, but the quality should be good.
I also was looking for something wide, portable, light, with very high quality and cheap, but...

May be The Samyang 12mm F/2 in a APS-C mode
I use the website bellow to check what is on offer on the market from time to time, as I got confused with so many lens coming up (and I am getting older and forget):
For example all wide Full frame lens for E-mount (35mm and bellow) at the moment offered by BH:
