Venus Optics releases the Laowa 9mm F5.6 rectilinear lens for full-frame mirrorless cameras

30 Jun

Venus Optics has announced the release of the Laowa 9mm F5.6 FF RL, a lens that takes the title of the world’s widest rectilinear lens for full-frame camera systems.

The lens features a 135-degree angle of view and is constructed of 14 elements in 10 groups, including two extra-low dispersion elements. It isn’t one of Venus Optics’ ‘Zero-D’ lenses, but it features ‘very low’ distortion, which makes it a solid option for landscape, architecture and real estate photography.

In addition to the ultra-wide field of view, the lens also features an incredibly short minimum focusing distance — just 12cm (4.72”) and uses a five-blade aperture diaphragm. The lens measures 60mm (2.4”) in both length and diameter and weighs just 350g (12oz).

Below are a few sample images from Venus Optics:

The Laowa 9mm F5.6 FF RL is available in Leica M, Sony FE, Nikon Z and L-mount. This marks the first time Venus Optics has designed a lens for Leica M-mount and to celebrate the occasion, Venus Optics is releasing the M-mount version in black and silver varieties. the Leica M-mount version costs $ 900, while the Sony FE, Nikon Z and L-mount versions costs $ 800.

Venus Optics to launch ‘world’s widest F2.8 rectilinear lens’

26 Jul

Chinese optical manufacturer Anhui ChangGeng Optical Technology Company Limited, or Venus Optics, is preparing to introduce a 12mm lens that it claims will be the world’s widest F2.8 lens with fully corrected distortion. Going under the Laowa brand name the lens will be called Laowa 12mm F2.8 Zero-D and will be officially announced on July 30th via a Kickstarter campaign.

Venus Optics says that the lens has almost no distortion, hence the ‘Zero-D’ in the name, and has loaned a test unit to a blogger Nicky Bay who has a preview with images on his website. The lens will be manual focus only, will feature an aperture range of F2.8 to F22 and is due to have a seven-bladed iris with clicking stops. The company is also said to be launching a Magic Shift adapter, according to Bay, that allows +/-10mm of shift while converting the lens to a 17mm focal length. The converter will be for Sony E-mount users only.

Specification published on the Laowa Facebook page.

Of course, this isn’t the world’s first rectilinear 12mm with a fast aperture, as F2 and F1.4 12mm lenses exist for the Micro Four Thirds system, and there are Zeiss F2.8 and F2 Samyang 12mm lenses for APS-C sensors, but this lens is designed for full-frame cameras.

The lens, which will be made in Canon EF, Nikon F, Sony A, Sony E and Pentax K mounts, is expected to retail at $ 949, but supporters of the Kickstarter campaign will be able to get one from $ 649. The Magic Shift will cost $ 300 and a square filter adapter will be $ 50.
