Chinese lens manufacturer Venus Optics has introduced a new Ultra Macro lens to its Laowa line-up with a 50mm F2.8 model that offers a 2x macro function. The Laowa 50mm F2.8 2X Ultra Macro APO is claimed to be the first-ever 2x macro lens for the MTF system, and has a minimum focus distance of 13.5cm (5.3in).

Marked with the company’s ‘CA Dreamer’ slogan, the lens has apochromatic correction achieved with three extra-low dispersion elements in the 14-elements-in-10-group construction. The company says lateral and longitudinal chromatic aberrations are corrected and that out-of-focus highlights appear free of color fringes. As the lens provides the view you’d expect from a 100mm on a full-frame sensor Laowa says it also makes an excellent portrait lens.

The lens is chipped and allows body-controlled apertures as well as full EXIF data to be recorded in the image metadata. The lens has a 7-bladed iris, a 49mm filter thread and it weighs 240g (8.4oz), while the short flange distance has allowed the company make it just 79mm (3.1in) in length.

The Laowa 50mm F2.8 2x Macro costs $400 before tax and is available to purchase now on the Laowa website.

Press release:

Venus Optics announced the world’s first 2x macro lens for MFT: Laowa 50mm f/2.8 2X Ultra Macro APO

Venus Optics, the camera lens manufacturer endeavoring in unique ultra-macro lenses, announce the release of Laowa 50mm f/2.8 2X Ultra Macro APO Lens. The new 50mm lens is specially designed for Micro Four Thirds (MFT) cameras and it is the first- ever 2X macro lens designed for this sensor size. The lens also features an apochromatic (APO) design to minimize the chromatic aberrations across the frame. The ex-VAT retail price is USD 399/pc and pricing may vary in different countries.

1) Focus from infinity to 2X macro magnification

Unlike most of the MFT macro lenses in the market which can focus only up to 1X, the new Laowa 50mm macro lens offers a 2X maximum magnification ratio along with a minimum focusing distance of 5.3” (13.5cm). It has become the first lens ever designed with a greater- than-life-size (2:1) maximum magnification for MFT cameras, allowing photographing close subjects with finer details. The wider magnification range also makes itself flexible for shooting subjects at different sizes. The lens can focus to infinity and serve as an excellent portrait lens with its 100mm equivalent field of view on 35mm sensors.

2) Equipped with a CPU chip and motor (Automatic aperture)

The lens is equipped with a CPU chip and motor and the aperture can be controlled via the camera body. All the lens data is directly recorded on EXIF. Moreover, the focus magnifier would automatically triggered for easier focus control when the focus ring is rotated.

3) Apochromatic optical (APO) design

The new 50mm f/2.8 2X Ultra Macro has a optics design with 14 elements in 10 groups, three out of which are extra-low dispersion glasses to minimize chromatic aberrations across the frame.
This lens has inherited the exceptional APO design from Laowa 65mm f/2.8 2x Ultra Macro APO, where both lateral chromatic aberration (LaCa) and longitudinal CA (LoCA or Bokeh Fringing) are eliminated.

4) Lightweight & Compactness

The 50mm lens is extremely compact and light in weight. It measures 3.1” (79mm) long and weighs only around 8.4oz (240g). Venus Optics take advantage of the short flange distance of mirrorless cameras and compress the size of the lens to the minimal. An internal focus design is also adopted so that the length of the lens can be maintained during focusing.

5) Compatible with MFT

With the previous success of the Laowa 65mm f/2.8 2x Ultra macro APO which was optimized for APS-C, the new 50mm lens is specially developed for MFT mirrorless camera users. It can be used on Panasonic, Olympus, BMPCC 4K, etc.

6) Pricing & Availability

The lens is currently available to order in authorized resellers and in Venus Optics official website (http://www.venuslens.net/). Shipping starts immediately. The ex-VAT retail price in the US is USD 399/pc. Pricing may vary in different countries.
