Product Description

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 abberations 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.

  1. :

    Good day,
    is the lens for 24 mm x 36 specified Full Frame?
    This is not to be found.

    Regards

    B. Baumann

    • :

      Yes. It is a 24 x 36mm full frame lens.

  2. :

    In the upgrade options it says “one more adaptor (Remark the conversion you need)”

    I do not understand what that means.

    Has the lens interchangeable mounts? Like a T-mount or something?
    And, if it has, how can you tell what other mount you want in this form?

    • :

      Hi Roland,
      It means you can buy an extra adapter. For example if you buy the lens in Canon mount and add an extra adapter (Canon to Fuji X), then you can use the lens on Canon as well as Fuji system.

  3. :

    Hi, Does this lens work with Sony a6000 camera (APS-C)?
    If so, what is the difference between the options “Mount: Sony FE” and “Mount: Sony FE (with adaptor) +$30)”?

    • :

      Yes! it works with Sony A6000. Sony FE mount = You can only use the lens in A6000 (or other Emount bodies). Sony E mount= You can use the lens in both Canon/Nikon and A6000.
