After reading countless great reviews of this lens, I decided to give it a shot and purchased it for architecture and astrophotography. I often thought to myself that the accolades of this lens seemed too good to be true for the price, and unfortunately, I found this to be the case. I didnt even get so far as to test it for astrophotography, as the quality from the images I shot in natural light proved to be enough for me to decide that this lens was not worth keeping. Even stopped all the way down to f/11 the Rokinon was somewhat soft and lacking in sharpness. Additionally, I noticed purple color fringing on high contrast edges at various apertures. Yes, I can address this in post, but I prefer to spend less time editing not more. Maybe Im spoiled by Fujinon glass, but I KNOW the quality of images that my Fujifilm cameras and lenses are capable of producing, so I do not want to settle. Perhaps expectations were too high, or my copy was defective, or maybe it was both. For now, Ill go back to using my XF 16-55mm for Astrophotography, which is fantastically sharp even wide open in low light, and then eventually buy the 14mm f/2.8 prime for a wider astro/architecture option. Too bad, because what good is the extra stop of light the Rokinon f/2 produces if the images pale in comparison?
