Rokinon 12mm f/2.0 - Ultrawide Prime
So as luck would have it my Canon 10-18mm crapped out on me about 10 days before my trip to Japan.
The repair time on it is 6 to 8 weeks so in a bind I pulled the trigger on the Rokinon 12mm f/2.0 ultra wide with the Sony e-mount for my a6000. Overall this is a great lens, and when my Canon comes back I'm gonna have a hard time deciding which one to keep.
It's a prime lens (1 focal length) with 100% manual controls for focus & aperture. But with such a wide angle it's hard to get things out of focus unless they are 1 foot in front of you. When you nail to the focus, it's indeed very sharp, which is why you buy a prime over a zoom.
Anyways a few sample pics, if you're looking for a native mount Wide Angle for the a6000, this one's not a bad choice. Provided you're comfortable with the manual focus.
