From the editor
A compact and lightweight wide-angle lens that fits well with the ideology of the LEICA M system and is suitable for street or travel photography. The focal length and speed were apparently chosen with the Leica Summaron-M 28/5.6 in mind, but the Chinese lens differs from it both externally and optically. 7Artisans was unable to make its lens as compact as the German one, or did not pursue such a goal. The lens uses non-standard 35.5mm screw-in filters, so finding them will be quite difficult.
