The new Laowa 105mm f/2 Smooth Trans Focus Lens incorporates an 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”).


The new Laowa 105mm f/2 Smooth Trans Focus Lens offers two separate diaphragms. 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.

The lens houses with 11 elements in 8 groups with 1 piece of High Refractive elements, 3 pieces of Low Dispersion elements and 1pc of Apodisation element. This optical design is proven to deliver images with extreme sharpness and limit the chromatic aberrations at its lowest. The enclosure of the lens is made of metal to strengthen its durability.
