Laowa 105mm f/2 (T3.2) Smooth Trans Focus – the Bokeh Dreamer is lens with unique optical design with an apodization (APD) element next to the aperture. The APD element resembles the function of an ND filter which becomes thicker towards the perimeter, gradually reducing the amount of light transmission towards the periphery to produce a soft, natural and beautifully diffused out-of-focus rendition (or called bokeh).

This Lens offers two separate diaphragms (pic). The stepless 14-bladed perfectly circular aperture, in conjunction with the apodization element gives this lens the ability to produce smooth and pleasing bokeh. It is also useful for videographers to control the amount of light passes through the lens. The 8-bladed aperture is to determine the effective aperture opening (f-number) and the depth-of-field formed.
