The “C” in the Zeiss ZM series means the revival of classic lenses. This lens directly inherits the elements of the famous Sonnar 5cm F1.5. The drawing is very classical and has a certain atmosphere. The corners have a little falloff and the rough bokeh. The bokeh is mostly natural in the front and behind, but it becomes double-lined at a middle distance. The depiction significantly improves as you stopped down one f-stop. In other words, it’s a very classic lens, but it’s not as difficult as real old lenses. I recommend this lens to someone who wants to go a little off the rails of modern performance, yet don’t want to get on the creaky rails of real old lens.※Vol.02(with LEICA M Monochrom)
