Another seemingly extraordinary photographic lens from Asia, this time from the Chinese giant, Chinese lens maker Venus Optics has announced a portrait lens that uses apodizer element, a technique that allows glass to have a different thickness at its edges compared to glass. center. ? and dual apertures to produce a better appearance in blurred reflections, the much appreciated bokeh. The company claims that the apodization element of the new Laowa 105mm F2 STF acts as a radial gradient filter that darkens to its outer edge. It is supposed to help produce smooth tonal transitions on diffuse discs. The element works in conjunction with a 14-blade diaphragm which Venus Optics says constitutes a constant circular aperture just before the light encounters the second main aperture, which always determines the f-number and depth of field.
This approach is very similar to that used in the Minolta lens (and, more recently, a Sony lens) 135 mm STF F2. 8 [T4. 5].
- The lens uses 11 elements arranged in eight groups and includes a single element on the front that has a high refractive index and three types of low dispersion glass.
- The company states that this project “demonstrated that it provides images of extreme sharpness and limited chromatic aberrations to its minimum level.

The all-metal lens will be available in Canon EF, Nikon F, Sony FE, Pentax K and Sony A camera mounts. The Loawa 105 mm F2 STF lens will cost $699.
Anhui China, 10 March 2016? Venus Optics, a Chinese camera lens manufacturer that launched the world’s largest 1:1 macro lens last June, just released another extraordinary lens, the Laowa 105mm f/2 lens (t/3. 2) Smooth Trans Focus for DSLR cameras.
The new Laowa 105 mm f/2 Smooth Trans Focus lens incorporates a unique optical design, with a nickname element (APD) next to the aperture. The APD element resembles the function of an ND filter that shrinks towards the perimeter, gradually reducing the amount of light transmission to the periphery to produce a smooth, natural and well-distributed blur (or also called bokeh).
The new Laowa 105mm f/2 Smooth Trans Focus lens offers two separate diaphragms. The perfectly circular opening of 14 continuously variable blades, combined with the nickname element, gives this lens the ability to produce a smooth and pleasant bokeh. for users to control the amount of light passing through the lens. The opening of 8 sheets is what determines the actual size of the aperture (number f) and the depth of the formed field.
The lens consists of 11 elements in 8 groups with one piece of high refraction elements, 3 elements of low dispersion and 1 part of apodization element. This optical design has been proven to provide extremely sharp images and limit chromatic aberrations to their minimum. The lens body is made of metal to enhance its durability. Canon EF, Nikon F, Sony FE, Sony Alpha, and Pentax K mounts are available.
The Laowa 105 mm f/2 Smooth Trans Focus lens will be available from authorized dealers and on the official English website. The recommended over-the-counter price is US$699. Free shipping will be available during the promotion period.
The advance order begins today and delivery of Canon EF/Nikon AI/Sony FE mounts will begin from April. Delivery of Sony A/Pentax K assemblies will begin in May.
