Brightin Star 12mm f/2 III 12mm
A fast f/2 maximum aperture and 10-blade diaphragm produce bright exposures and crisp 10-point starbursts from point light sources. Two aspherical and two ED elements control distortion effectively, delivering edge-to-edge sharpness for an 18mm full-frame equivalent wide-angle view. It's best for landscape and architecture photographers on Canon EF-M cameras who need manual focus precision and dramatic close-up capability with a 7.1-inch minimum distance.
