After the Laowa 60mm f/2.8 Macro 2:1 and the Laowa 15mm f/4 Shift Macro 1:1 lenses, the Chinese company Anhui Changgeng Optical Technology Company Limited, better known as Venus Optics (see, will announce shortly a new 24x36 lens: the Laowa STF 105mm f/2 (T/3.2).

Update: the lens is now available for pre-order.

The Laowa STF 105mm f/2 is a portrait lens with an apodization filter that gives a more progressive and velvety bokeh than an ordinary lens (STF stands for Smooth Trans Focus). This is the same principle as for the Minolta AF / Sony 135mm f/2.8 [T/4.5] STF and close to that of the Fujinon XF 56mm f/1.2 R APD. The Laowa has the advantage over the Sony of being one EV brighter. Hereafter its main features:

  • 11 elements, including the apodization filter, 1 element made of glass with high refractive index and 3 elements made of low dispersion glass, in 8 groups
  • Manual focus (the apodization filter is hostile for phase-detection autofocus)
  • Minimum focusing distance: 90cm
    Maximum magnification: 0.16x
  • Filter diameter: 67mm
  • Dimensions: 76 mm (maximum diameter) x 98.9 mm (length) (depending on lens mount)
  • Weight: 745 g (depending on lens mount)
  • Available mounts: Canon EF, Nikon F, Pentax K, Sony A and Sony E
  • Available in black and silver
  • Launch date: January 18, 2016
  • Price in China: the equivalent of €500-550 (probably more in Western countries)
  • Shipment should start in the summer of 2016

    Ita nice that stf is for other mounts, but if youre a Sony shooter youre better off with the Sony 135 stf lens, it renders the best background available.

    • Marc W.

      And how much is the Sony?

      • Ethan

        When youre buying a lens for the stf effect, you expect it to do its job of smooth transition. The sony is $1400 new, BUT it actually has a smooth transition, unlike this lens.

        This lens is half the price for half of the effect.

        • Marc W.

          How much is this lens? I must have missed it.

          • Ethan

            500 euros

          • Marc W.

            For that huge of a difference, people not needing AF should really consider this.

          So by this post I’m going to assume that you’re a product tester for this lens? No? Then I’d love to know how you’ve come to such grand conclusions based on a handful of small JPEGs.

    • harvey

      how can you tell that since there are no images from it?

      • Ethan

        Theres samples from sonyalpharumors.con

      • there are multiple links to sample images in my post as well

    • Corbin Dallas

      I’ll save the extra $1000 if this lens is decent, thanks 😉

    It’s nice to see small companies like this going for unusual gaps in the market, rather than just trying to undercut existing lenses. It’s no fun if we all play with the same toys.

      No kidding. 70-200 anyone? What? EVERYONE?!

  • Slaven

    Blame Sony, who forgot about STF.

  • Alfred

    Still waiting for the announcemet….

  • Rachel Davis

    the STF ring is such a bonus for video makers.
