I believe this is a cheaper alternative to the Rokinon 14mm. Clear image. I had to crop it so it's not exactly 12mm but it's still pretty wide for my video/streaming use. I tried Roquinone and returned it because I just didn't like the results of what I needed. This is easier to justify, it's very similar and looks great. FYI, I'm a noob when it comes to cameras/lenses so take what I say with a grain of salt.
