I bought this lens for my Sony FS-100 camcorder and it works really well. I recently got my hands on a Sony A7 and noticed that when used on an FF camera, the image circle projects even larger. There's no way you can use it for FF, but you can widen it significantly by using 16 f/2 and cropping afterward. It's very sharp and has good manual focus. I like pulling the focus as the depth of field is very shallow and the focus feature works great. I have all the other Rokinon (Samyang) lenses and I really like them. They are affordable, very clear and have enough contrast for both videos and photos.
