Laowa 12mm f/2.8 Zero-D Pentax K MILC/SLR Wide lens Black

12mm, f/2.8, Zero-D, Pentax K Ultra Wide Angle Lens is one of the most important lens that every photographer should have one in his camera bag. There are a lot of wide angle lenses in the market, offering from a few hundred to a a few thousand dollars. However, these UWA lens are not perfect. They are suffering from dramatic barrel distortion (2-5%), poor peripheral sharpness or huge physical size. We therefore spend a lot of time to come up with a design which is truly perfect and overcome the frustration of photographers. That’s where the LAOWA 12mm f/2.8 ZERO-D comes from.
