Argus 35mm F/0.95

A new Laowa lens for your EOS R full frame camera system. The Laowa Argus 35mm f/0.95 FF. The lens is currently available to purchase via Venus Optics official website and authorized resellers. The US price for Laowa Argus 35mm f/0.95 FF is $899.

Press release:

Anhui China, Sept10, 2021–Venus Optics, the manufacturer specialized in making unique camera lenses, is proud to introduce Laowa Argus 35mm f/0.95 FF, the world’s fastest 35mm lens and widest f/0.95 lens ever designed for full frame cameras. It is a breakthrough of the camera lens industry,and it inherits Venus Optics’ objective to offer innovative and groundbreaking products. It provides awide63.4° angle of view together with superb shallow depth of field for both photography and videography.

Key Features:

  • Wide perspective with ultra-shallow depth of field
  • Ultra-fast f/0.95 aperture for low-light shooting
  • Superb sharpness at f/0.95
  • Aperture Ring Click Switc
  • Internal Focus design
  • Low Focus Breathing with extended Focus Throw
  • Exquisite Bokeh

Widest f/0.95 lens & Fastest 35mm lens for Full Frame Format

Laowa Argus 35mm f/0.95 FF is the FIRST full frame 35mm with f/0.95 ultra-fast aperture. Makes it the fastest 35mm and widest f/0.95 lens in the market. The optical performance is maximized by incorporating1 ED glass element, 1 aspherical lens element and 4 high-refractive-index glass materials. The extraordinary shallow depth of field and dreamy bokeh created by f/0.95 is the trump card for portraits. In the meanwhile, its unbeatable performance in low light conditions for obtaining sharp and outstanding images makes it a must-have tool for every photographer and videographer.The wide FoV allows more backgrounds being recorded into the image and thanks to the f/0.95 aperture, a shallow depth of field can still be achieved.

Aperture Ring Click Switch

Aperture ring click switch mechanism offers options for the photographer and videographer to choose either clicked or de-clicked aperture ring. No uneven exposure

Internal Focusing

Laowa Argus 35mm f/0.95 FF inherits an internal focusing characteristics from Argus 33mm f/0.95 CF APO. It maximizes the optical performance in both infinity focus and minimum focusing distance by enhancing the stability. Also, it prevents the dust or ashes falling into the lens. This feature is extremely welcomed by videographers as accessories like matte box will not move while pulling focus. Absolute advantage for both photography and videography.change when changing the aperture during shooting.

Low Focus Breathing with Long Focus Throw

The low focus breathing and long focus throw are perfect for narrative filming and selective focus control. It eliminates the distraction of the changes in angle of view when moving focus from one object to another. Along with the accurate focusing obtained by the 300° focus thread makes it become the ideal lens for videography.

Exquisite Bokeh

The 15-aperture blade produces silky smooth, round bokeh without hard edges. A dreamy Bokeh adds character to the images which is perfect for visually appealing images.

Technology breakthrough

f/0.95 and wide angle lenses with good optical performance are known to be heavy and bulky, making it inoperable in certain conditions. Dayong Li (Chief optics designer of Venus Optics) has managed to strike a balance between the ease of customer operation and optical performance. They push the optics design to another level by crafting a lens that can cover mainstream full frame sensor, have a good optical performance, offer a wide perspective and extremely shallow depth of field.

Canon Patent: More RF mount lenses, RF 27mm f/1.4 And RF 35mm f/1.4

Canon Patent

And yet another Canon patent for RF-mount lenses spotted by asobinet.com. An RF 27mm f/1.4 and an RF 35mm f/1.4.

From the patent abstract:

In recent years, image pickup devices such as digital still cameras, video cameras, surveillance cameras, broadcasting cameras, and silver halide photography cameras using a solid-state image sensor have become more sophisticated. As an optical system used for this, the entire focus group is required to be miniaturized. Further, there is a demand for an optical system capable of satisfactorily correcting chromatic aberration, curvature of field, etc. at the time of shooting at the nearest distance while increasing the shooting magnification when focusing from infinity to the nearest distance. Further, with the shift to mirrorless large format cameras, there is a demand for a lens having a short back focus, a small size, and a large aperture. As an optical system that satisfies these requirements, a lens group having a positive refractive power, a focus lens group having a positive refractive power, and a focus lens group having a positive refractive power, which are arranged in order from the object side to the image side, are used.

It seems keeping thing small and light-weighted is a major topic in Canon’s R&D department.
