The lens is incredibly sharp! I've done some preliminary testing since reading that the Samyang/Rokinon/Bower lenses had some quality control issues, but I seem to have had some luck with this and the other Rok lens I have. The lens is heavy and feels premium. The focus ring is smooth-running, pleasant clicks can be heard when changing the aperture. The lid and hood look a little cheap, but I think they do the job. Can't wait to use this on my next astro walk. I will definitely update if there is anything to report.
