Excerpt: Even though many people who take pictures can't handle using a manual focus lens...I love them! This lens is great for taking wide shots. Shoot at f8 or above and set to 'infinity' and you got yourself a great wide shot!
Excerpt: I was having a hard time finding a lens I could use for my A7s that was an e-mount. I has having so many problems with my adaptors for my A7s so I decided to look at sony lenses, but they are expensive. Rokinon was the perfect solution.This lens quality is good and the images turn out great as well.
Pros: Consistent Output, Durable, Easily Interchangeable, Rugged, Strong Construction
Excerpt: I primarily use it for shooting northern lights and the Milky Way and it is really sharp for the price and it's focal lenght. I use it on a Sony a7 and I didn't found any problems most people seems to talk about, at least on my copy. The infinity mark is spot-on and there's no signs of decentering.
Pros: Consistent Output, Easily Interchangeable, Rugged, Strong Construction
Excerpt: I rarely use this lens because of its size. I use my Voigtlander 35mm 1.7 Ultron for wide angle shots. Not filter friendly. Corners are soft. Not sharp enough. Not happy with the contrast. You cannot find any ultra wide angle lens in this price point.
Cons: Difficult to Clean, Heavy, Not Filter Friendly, Soft On Corners
Excerpt: i enjoy using this len its very wide aperture makes nice to have in evening around the camp fires. sharpness is so so i have had good and bad luck with using it, but i could also be my learning curve.
Well worth it if you focus on learning and learn how to focus!

Summary: The 1st couple of times I used this lens, I had a difficult time taking pictures that were actually in focus. They seemed focus on my preview but when I got home and zoomed in on parts of the image, mainly the part that mattered, the images were out of focus.
