Bokeh part 2

I previously wrote about bokeh, describing what it means (the nature of the rendering of out of focus areas), how it is commonly used, and I also looked into how the aperture setting affects the out of focus areas in the picture.

This time, I want to look more closely at how the bokeh differs by lenses. I've tested some common fast lenses from the Micro Four Thirds lens lineup, laid out here:



Second row: Olympus 45mm f/1.8, Leica Lumix 45mm f/2.8 macro, Lumix X 12-35mm f/2.8
First row: Lumix G 14mm f/2.5, Lumix G 20mm f/1.7, Sigma 30mm f/2.8 DN and Sigma 19mm f/2.8 DN
