Any Leica lenses, released when or after the digital M camera was released, have outstanding resolving power. This 18mm is no exception and astonishingly sharp. The combination of this lens and the digital M enables landscape shooting. Once I see the results of this high-res combination, I even think the decline of 135 films is inevitable. Distortion is well corrected and it’s sharp across the frame. It has a high contrast without sacrificing tonality. Anyway, it’s a wonderful lens.
