Zeiss Touit 32mm f/1.8 Planar

Bokeh (Glassware, Sony NEX-7)

Bokeh: the way the lens “draws” out of of focus areas, both in the foreground and background. Bokeh can have such a visual impact, either pleasant or distracting or neither, that some photographers might choose a lens for its rendering style, or avoid a lens for an unappealing rendition (wide open or stopped down).

When high macro and micro contrast combine with pleasingly smooth and yet “3D” bokeh, the lens can exert an alluring quality that test charts (“lab tests”) can never articulate, yet seasoned pros often have their favorite lenses for these hard to quantify qualities. Your author is no exception.

Worth noting is that bokeh is often grossly simplified to “smooth blur”. In that regard, some lenses said to have “good bokeh” might really be more about an even and pronounced background blur (e.g. f/1.2), but without the contrast, and so lacking that extra “pop” so important to the entire visual effect. Increasing experience with a variety of fast lenses steadily hones ones appreciation for the differences.
