Samyang Ultra Wide Angle for an a6000
I'm looking for a lens for architecture, lanscape and real estate.

12mm F2.0 NCS CS (

10mm F2.8 ED AS NCS CS (

I'm not sure what could be better for me. 10mm are gorgeous, 12mm is not too much more but 2.0 is really interesting. In the other hand 14mm full frame, that's like 9mm in apsc could be really great once I will upgrade to an a7. something will happens in a couple of years I guess.
I'm oriented to the 12/2, what's your thought?
