Samyang 8mm f2.8 II UMC Fisheye Black Lens (Sony E-Mount)?
@olli66 gosh you are fast!!!
Remember it's a manual lens, and being e-mount is locked into that system. (Which may or may not be an issue for you).
It does look like a nice lens for e-mount though, at a good price.
It's a lot more money and you'd need an adapter, but Canon's 8-15mm fisheye zoom is my favorite.
