Wide angle prime lense for Sony E-Mount APS-C cameras. Excellent auto focus, very good build quality with a very smooth rotating manual focus adjustment. Works the same as the day I bought it. No petal hood though, I left it behind on a hike accidentally. I am selling the lense because I am a student and can only afford to have 1 lense. I decided I need to give this up to get a zoom lense instead.
