If you’re not familiar with Leica, you probably are not aware that they are well known for shooting at low apertures and creating bokeh. Bokeh is the blur seen in photography or more specifically the quality of the blur. Each Leica lens is known for there unique bokeh. Yes, you will find this with almost all other cameras and lenses but many don’t have the quality seen in Leica lenses. I’ve shot with many Canon dSLR’s and low aperture lenses and have never been impressed as much as I am with the Leica m-mount lenses.
Below are a few examples of shots taken with my Leica 50mm Summilux and 35mm Summicron.
