Lens is very good and sharp even at wide open. I purchased it for Night photography and Milky way photo, I still have to use it for that purpose.

Very fast, relatively sharp lens with minimal defraction, used specifically for aurora and astro for a season and pretty happy with it. Very comparable to the sony 20mm 1.8, but takes up about twice the space in your camera bag. Over all a pretty good lens for the money.
