It is marketed as the "Bokeh Dreamer" lens.[1] Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 157.5mm. Optical propertiesThe lens features an apodization filter element within the lens itself which lends itself to producing creamy smooth bokeh at the expense of light gathering capabilities. The lens features the bokeh of an f/2.0 lens but maintains the light-gathering of an f/3.2 lens, requiring brighter lighting conditions from the environment to compensate. See also
