SIGMA Proclaims Launch of 70-200mm F2.8 DG DN OS | Sports activities Lens

Ronkonkoma, NY, November 16, 2023 – SIGMA Company of America, the US subsidiary of SIGMA Company (CEO: Kazuto Yamaki. Headquarters: Asao-ku, Kawasaki-shi, Kanagawa, Japan) is happy to announce the official launch of the highly-anticipated SIGMA 70-200mm F2.8 DG DN OS | Sports activities lens.

A dependable and light-weight large-aperture telephoto zoom lens designed solely for full-frame mirrorless cameras, the 70-200mm F2.8 DG DN OS | Sports activities is offered for Sony E-mount and Leica L-Mount. Combining high-speed AF, remarkably efficient OS, distinctive mechanical reliability, and superior optical efficiency, this high-performance lens is purpose-built to fulfill the rigorous calls for of execs, and is appropriate for a variety of kinds and genres together with nature, wildlife, photojournalism, motion sports activities, marriage ceremony and portraits. The lens will retail for $1,499 USD and will likely be obtainable by way of licensed retailers on December 7, 2023.

Mud and splash-proof development, high-performance optical stabilizer (OS), and an interior zoom mechanism that doesn’t have an effect on barrel size, are all options designed for essentially the most demanding photographic circumstances. Additionally it is the primary SIGMA DN zoom lens to be outfitted with an aperture ring (click on/declick sort).

Streamlined optical design and a multi-material construction that includes magnesium and TSC have resulted in a light-weight lens physique. A brand new compact tripod collar and foot additionally assist reduce weight, as does a CFRP (carbon fiber-reinforced plastic) lens hood. In comparison with the 70-200mm F2.8 DG OS HSM | Sports activities for DSLR cameras (1,805g for SA mount), the 70-200mm F2.8 DG DN OS | Sports activities is considerably lighter (1,345g for L-Mount).

That includes Twin HLA-driven floating focus for quick, correct AF, the main target lens is pushed utilizing a high-thrust HLA (Excessive-response Linear Actuator) as the main target actuator, and a floating focus is used to realize high-speed AF drive. The floating configuration of this lens, through which the 2 focus teams are pushed in reverse instructions, reduces the quantity of motion of every focus group to about half that of a single group focus system, attaining extraordinarily quick AF that’s extremely responsive. The newest OS2 stabilization algorithm achieves picture stabilization efficiency of seven.5 stops on the Extensive finish and 5.5 stops on the Tele finish.

The SIGMA 70-200mm F2.8 DG DN OS | Sports activities has very minimal focus respiration on each the large and tele ends, making it a robust lens for video functions. The minimal change in heart of gravity allows secure taking pictures in all conditions, together with handheld, on a tripod, and with a gimbal. Throughout zooming, 5 teams are moved to suppress aberration fluctuation, attaining excessive optical efficiency all through the zoom vary.

Three aspherical lenses are used, as they’re now indispensable for superior optical efficiency and streamlined lens development. The exceptionally excessive precision of the aspherical lenses, which reap the benefits of the technical capabilities of SIGMA’s solely manufacturing facility, the Aizu manufacturing unit, additional improves optical efficiency. The included floating focus is advantageous in enhancing short-range efficiency, guaranteeing a secure, high-level picture high quality all through the complete vary from the minimal focusing distance to infinity.

Excessive-speed AF with a twin HLA

The SIGMA 70-200mm F2.8 DG DN OS | Sports activities with floating focus has a construction through which the 2 focus teams transfer in reverse instructions, thereby lowering the quantity of focus lens motion by about half. As well as, the usage of an HLA (Excessive-response Linear Actuator) motor in every of the 2 focus teams allows high-speed autofocusing. Along with being quick and correct, the lens additionally employs a management program that’s designed to be quiet, so customers can shoot motion pictures comfortably with out worrying about noise.

OS2 algorithm in optical stabilizer operate

The newest OS2 optical stabilization algorithm gives a particularly excessive picture stabilization impact of seven.5 stops on the large finish and 5.5 stops on the telephoto finish*. The lens is provided with two OS modes: Mode 1 is appropriate for normal taking pictures, and Mode 2 is good for panning pictures of motorsports and different sports activities. In Mode 2, SIGMA’s Clever OS, an algorithm specifically designed for panning pictures, allows efficient picture stabilization even when the digital camera is moved vertically or diagonally, regardless of the horizontal and vertical orientation. This ensures that the topic’s motion might be captured with out dropping the panning shot impact.

* Primarily based on CIPA tips (Measured at 70mm and 200mm with a 35mm full-frame picture sensor)

Designed to reduce focus respiration

The lens has been designed to suppress focus respiration. The change in angle of view as a result of focus shift is minimized, making a natural-looking focus shift when recording video.

Designed to reduce flare and ghosting

Flare and ghosting, which scale back picture high quality, are addressed below all circumstances of incident mild based mostly on essentially the most superior simulation know-how. Excessive backlight resistance allows clear and sharp photographs below any lighting circumstances.

2. Prime-level construct high quality condensed right into a extremely cell lens
