The Chiaro 1.5-inch (38mm) f/1.9 lens has been designed as a tribute to the classic Dallmeyer Super Six lens design from the 1930s, which shared the same f/1.9 aperture and was famed for its distinctive painterly bokeh and ethereal image quality.

Wide open at f/1.9, the Chiaro 1.5-inch is said to deliver "mesmerizing 3D spatial separation (subject isolation).

Although by Leica M-mount lens standards, even at this price the Chiaro 1.5-inch f/1.9 is reactively accessible.
