                OpticalZDefocus is a physically accurate ZDefocus, which controls circle of confusion (coc) size based on lens geometry using the depth of field equation. Set your lens and film-back characteristics, your focus distance, and adjust the size of your bokeh with the aperture size, just like a real lens.
