Rokinon 20mm f/1.8 fro Micro Four Thirds

[NGH]

Has anyone used and can recommend the Rokinon 20mm f/1.8 for a MFT camera?

I am thinking about getting an inexpensive 20mm lens for my Pen-F and this seems like a good option. I have a 7Artizans 25mm which gives me a 50mm equivalent and think I could use something just a little wider, the 20mm would give me 40mm and that sounds about right.

Any other suggestions welcome too but can't spend more than a few hundred dollars
