Confirmed: Venus Optics working on new line of ultra-fast ‘Argus’ F0.95 lenses

21 Jan

Update (11:30 EST, January 20): Venus Optics has confirmed to DPReview that it’s working on not just one, but multiple F0.95 lenses. A Venus Optics spokesperson says Venus Optics does ‘not have further information about these lenses’ at this time and concluded their statement saying ‘As usual, we are just trying to create something unique, good quality and affordable for photographers.’ The headline of this article has been changed to reflect this confirmation.


According to a report from FujiAddict, Venus Optics, manufacturer of the Laowa lens brand, is working on a new ultra-fast F0.95 lens for DSLR and mirrorless full-frame and APS-C camera systems.

FujiAddict’s report, which says the lens will be denoted by the ‘Argus’ moniker, is substantiated by an image posted to Chinese social media platform Weibo that claims to show a frame from a presentation that simply shows the words ‘Laowa F0.95.’ At this time, no information is given regarding the focal length or specific mounts this purported lens will be available for. However, FujiAddict claims ‘Many are speculating it will be wide and my contact says they expect it to be between 20–35mm.’

As noted in the report, Venus Optics isn’t the first third-party lens manufacturer to create an ultra-fast prime lens. In addition to the legendary Leica Noctilux F0.95 lens, SLR Magic has a slew of ‘HyperPrime’ lenses for both still and cinema photography.

We have contacted Venus Optics in an effort to confirm this report. This article will be updated accordingly if we hear back.

Canon patent shows off ultra-fast, ultra wide 14-21mm F1.4 RF lens

06 Mar

Canon hasn’t been shy about the improvements and flexibility its new RF mount affords lens designers, but if a recent lens patent ends up coming to fruition, it might just be the most interesting RF lens we’ve seen yet.

U.S. Patent Publication Number US 2018/0314060 details the optical design for an RF 14-21mm F1.4 lens, an ultra-fast, ultra-wide-angle lens that will inevitably have astrophotographers picking their jaws off the floor.

As with all patents, there’s a good chance the lens design will never make its way past the drawing board, but recent rumors suggest this very lens could be amongst the RF lenses Canon will be announcing in 2020.

Canon assured us the new RF mount would lead to unique lens designs — this may very well be one of the designs it had in mind.

Resistant to dust and moisture, the lens uses 14 elements in 9 groups, including 3 ED elements, along with Nano Crystal and fluorine coatings. The lens has 9 rounded aperture blades, and the aperture is electronically controlled, which keeps exposure consistent while shooting high-speed bursts. As you might expect, this is a heavy lens, weighing in at 985g/2.1lbs.

The 105mm F1.4 is expected to ship in late August with a $ 2,199.95 MSRP.

Press release:

GLAMOROUS GLASS: NIKON CELEBRATES 100 MILLION NIKKOR MILESTONE AND THE INTRODUCTION OF THE AF-S NIKKOR 105mm f/1.4E ED LENS

MELVILLE, N.Y. (July 27, 2016 AT 12:01 A.M. EDT) – Today, Nikon Inc. is celebrating a momentous NIKKOR production milestone as well as the announcement of the AF-S NIKKOR 105mm f/1.4E ED, a premium lens for the most discerning photographers. This luxurious new medium-telephoto lens is engineered to help create flattering images with gorgeous bokeh, while delivering impressive sharpness and beautiful color rendition. As a testament to a lasting legacy of high-caliber lenses, Nikon has also announced that NIKKOR lens production has reached the landmark achievement of 100 million units produced worldwide.

“Surpassing the 100 million lenses produced milestone is a great honor and a testament to the photographers who both love and rely on NIKKOR glass to get the job done,” said Kosuke Kawaura, Director of Marketing and Planning, Nikon Inc. “The AF-S NIKKOR 105mm f/1.4E ED represents the embodiment of the NIKKOR line of high-quality lenses, giving photographers a robust, well-balanced lens that provides intense sharpness, astounding image quality and background bokeh that is sure to be a favorite among portrait photographers.”

Captivating Image Quality
The AF-S NIKKOR 105mm f/1.4E ED is a fast, full-frame (FX-format), medium-telephoto prime lens and is the world’s first1 to strike the impeccable balance of 105mm focal length and large f/1.4 aperture for a truly outstanding optic. This new NIKKOR lens is ideal for professional and advanced enthusiast photographers, especially those capturing portraiture, from in-studio fashion to a golden hour engagement session on the beach. These users will love the precise sharpness from this fantastic glass, which provides a flattering compression to subjects with a sensational, sultry bokeh. Beyond the gorgeous image quality lies stellar resolving power, especially when used with Nikon DSLRs such as D5, D810 or D750.

The 105mm f/1.4E is a fast lens with endearing character, providing stellar optical performance, even in the peripherals. Sharp rendering is attained for shooting distant subjects throughout the aperture range – from maximum aperture to being stopped down by several stops. Gradual alteration from the focal plane helps render subjects in high-fidelity with a natural depth, giving colorful portraits and landscapes that little bit of extra “pop” to help create a truly distinct image. The AF-S NIKKOR 105mm f/1.4 is also an excellent choice for low-light photography, as its large maximum aperture allows photographers to shoot at the fastest possible shutter speeds. Additionally, this lens can reproduce point light sources faithfully without sagittal coma flare, even on the edges of the frame.

Masterful Lens Construction
Decades of precision, knowledge and experience are put forth into every NIKKOR lens, and the AF-S NIKKOR 105mm f/1.4E ED is an exceptional example of brilliant craftsmanship and Nikon technologies merging. Packed with the latest advanced optical innovations, the 105mm f/1.4 features Nikon’s electromagnetic aperture control technology for consistent exposures, even during high speed continuous shooting.2

On the outside, solid build quality is well-balanced for all-day shooting, while the lens is sealed and gasketed to resist dust and moisture. Additional Fluorine coatings are used on the front and rear elements, so that smudges, dirt or moisture are easily removed. Inside the lens, the optical formula consists of 14 elements in nine groups, which include three ED glass elements. A 9-blade diaphragm further helps to create a circular, pleasing out of focus area. The lens also features Nikon’s Nano Crystal Coat technology to significantly reduce instances of ghosting and flare.

The new AF-S NIKKOR 105mm f/1.4E ED joins other NIKKOR f/1.4 lenses in the Gold Ring Series, which include only premium primes with Nano Crystal Coat and pro-grade build quality. These other lenses include the AF-S NIKKOR 24mm f/1.4G, AF-S NIKKOR 35mm f/1.4G, AF-S NIKKOR 58mm f/1.4G, AF-S NIKKOR 85mm f/1.4G.

A Landmark in the NIKKOR Legacy
Nikon is also pleased to announce that the total production of NIKKOR lenses for Nikon interchangeable lens cameras reached the landmark 100 million milestone in mid-July 2016.

With a robust line-up of high-quality lenses for all types of photographers, the NIKKOR name has become synonymous with a rich history of superior lenses. Nikon continues to introduce new NIKKOR lenses that further optical technology, utilizing cutting-edge techniques and knowledge from experience cultivated over its long history. Such revolutionary advancements include Nano Crystal Coat, which acts as a powerful anti-reflection coating, and significantly reduces instances of ghosting and flare. More recently, NIKKOR lens technologies such as the use of Phase Fresnel (PF) and Fluorite elements have helped to create smaller and lighter lenses with superb balance and handling. Many NIKKOR lenses now also feature a Fluorine coat that helps repel a variety of contaminants such as dust, dirt, water, oils and grease. The introduction of an electromagnetic diaphragm has also helped to create lenses that provide consistently crisp exposures, even during high-speed shooting.

Pricing and Availability
The AF-S NIKKOR 105MM f/1.4E ED will be available in late August for a suggested retail price (SRP) of $ 2,199.953. For more information on Nikon’s latest products including their newest NIKKOR lenses, please visit www.nikonusa.com.
