Optical properties

The 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 a T/3.2 lens, requiring brighter lighting conditions from the environment to compensate.
