Laowa 105mm f/2 Smooth Trans Focus (STF)

$699.00

The Bokeh Dreamer with Ultra-sharp image and Silky smooth Bokeh.

Featuring an unique STF (Smooth Trans Focus) optical design. This award-winning lens incorporates an apodization (APD) element next to the aperture which resembles the function of an ND filter. It gradually reduces the amount of light transmitted towards the periphery to produce a soft, natural and beautifully diffused out-of-focus rendition. The chromatic aberration has also been controlled to the minimal.

Smooth Trans Focus: Ultra Sharp in focus & Silky Smooth Bokeh

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).

Dual Aperture Ring for still and motion shooting

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.

Superb Optical Quality with Close-to-Zero Chromatic Aberrations

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. Canon EF, Nikon F, Sony FE, Sony Alpha and Pentax K mounts are available.
