The definitive large-diameter standard zoom lens for any shoot

What photographers demand from the 24-70mm F2.8 specification is much more than outstanding image quality. They want all the features that make this a go-to lens for a wide range of photographic opportunities, including optical design ideal for the latest ultra-high-megapixel digital cameras, HSM (Hyper-Sonic Motor) for high-speed autofocus, OS (Optical Stabilizer) with powerful stabilization effect, dust- and splash-proof mount with rubber sealing, and a metal barrel for a stable, rigid feel. This all-new 24-70mm F2.8 lens from SIGMA delivers the performance and functionality that help pros succeed in news, nature, and many other fields of photography.

【Key features】

  1. The large-diameter standard zoom ideal for today’s ultra-high-megapixel digital cameras
  • Outstanding optical performance

Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements help minimize optical aberrations. To ensure outstanding image quality from the center to the edges of the photograph, the optical system minimizes coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control, The optical system also minimizes distortion, which can be particularly evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.

  • 24-70mm F2.8 lens that meets the high standards of the Art line

SIGMA has continuously pioneered 24-70mm F2.8 lenses that are a step ahead of the times. The first model of this specification, SIGMA 24-70mm F2.8 EX DG ASPHERICAL DF, launched in 2001. Representing the fourth generation of the family, the new SIGMA 24-70mm F2.8 DG OS HSM | Art accomplishes a challenging feat in optical design: incorporating optical stabilizer functionality in a large-diameter standard zoom. By leveraging all of its design and manufacturing expertise, SIGMA has ensured that this new lens fulfills the uncompromising requirements of the Art line for image and build quality.

  • Bokeh that is a cut above

At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are often used at wide-open aperture, SIGMA has paid close attention to the shape of the bokeh, aiming for perfect circularity.

  • Incorporating advanced aspherical lens processing technology

Aspherical lenses necessitate refined expertise in the design and manufacturing of advanced, high-performance lenses. SIGMA’s representative products to feature this technology were the SIGMA 12-24mm F4 DG HSM | Art and SIGMA 14mm F1.8 DG HSM | Art, which both incorporated a large ⌀80mm aspherical lens as their front lens element. Building on the success of these predecessors, the SIGMA 24-70mm F2.8 DG OS HSM | Art incorporates an aspherical lens element that helps achieve extremely high resolution. This element is much thicker at the center than the edges, and forming its unusual shape is a feat of manufacturing technology. Moreover, SIGMA processes the surface of this aspherical lens element with ultra-precise tolerances that are measured in hundredths of a micrometer. This extremely fine surface allows the SIGMA 24-70mm F2.8 DG OS HSM | Art to deliver a very natural and smooth bokeh effect, without the visible concentric rings that afflict typical aspherical lens elements.

  1. OS functionality and newly designed HSM for success on any shoot

Designed for advanced utility in a wide variety of situations, the optical stabilizer OS (Optical Stabilizer) offers a powerful stabilization effect. The newly designed large hypersonic motor HSM(Hyper-Sonic Motor) offers 1.3 times the torque of its predecessor and exceptionally stable performance even at lower speeds.

  1. Lens barrel designed for high rigidity

Since large-diameter standard zoom lenses tend to serve as a go-to lens and see frequent use, the SIGMA 24-70mm F2.8 DG OS HSM | Art is designed to stand up to the challenging shooting environments that pros encounter. To this end, the lens barrel contains a large amount of metal, while the external moving parts feature TSC (Thermally Stable Composite), which is resistant to thermal expansion and contraction. This structure contributes not only to the outstanding optical performance of the lens but also to its high rigidity and confidence-inspiring build quality.

  1. Other features
  • Mount with dust- and splash-proof design

Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing * helps provide peace of mind. In addition, the front lens element features a water- and oil-repellent coating that helps the lens perform well in the rain, near water, and in other challenging conditions.

*Except for the SIGMA mount.

  • Nikon electromagnetic diaphragm mechanism included

The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.

Note: Functionality may be limited on some camera bodies.

  • Fast AF with full-time manual focus
  • Designed to minimize flare and ghosting
  • High-precision, durable brass bayonet mount
  • Rounded diaphragm
  • Evaluation with SIGMA’s own MTF measuring system “A1”
  • Made in Japan

With outstanding craftsmanship

  • The lens barrel is engraved with the year of release
  • Compatible with Mount Converter MC-11
  • Available SIGMA USB DOCK

Makes customization and flexible adjustment possible

  • Available Mount Conversion Service

Allows use with another camera body

Nissin Air10s wireless commanders

The New Standard Nissin Air10s

An advance 2.4Ghz wireless TTL strobe commander

Nissin Air10s wireless commander

Nissin Japan Limited (Chairman Mr. Goto Chikara) proudly announces the Air10s, an advance NAS (Nissin Air System) 2.4Ghz Wireless TTL commander for Fujifilm, Sony, Micro Four Thirds, Canon and Nikon cameras, available in April 2017.

The Air10s is an advanced strobe commander in the N.A.S., Nissin Air System*1. The simple and clear dial layout with Color LCD display allows the user to seamlessly and quickly control a large group of strobes from a dark indoor studio, to a bright outdoor environment. It can control the NAS Ready strobes (i60A and Di700A) and the receiver Air R wirelessly.

Sustainable performance – easily updated via a Micro SD card slot

The Air10s has been equipped with a Micro SD card slot that allows users to update the device easily by themselves. Nissin plans on putting a Micro SD card slot on all future strobes and commanders.

Expand the creativity boundary – Control your strobes up to 100 meters*2

The device’s range of use has been greatly extended (when compared to older models) to a maximum distance of 100 meters, and the TTL Mode, high speed sync (FP sync) supporting up to 1/8000 High- speed shutter speed, rear curtain, and other functionalities can be controlled remotely.

Finest adjustment – supporting 1/3EV step in TTL flash exposure correction, and the smallest output down to 1/256*3

Used under the TTL mode, minimal adjustments are possible with just 1/3EV step. In addition, under manual mode, the device supports the lowest power adjustment down to 1/256, which comes in handy for highly sensitivity shoots.

Instant strobes setup – Manual output power instantly transform from TTL exposure data

The device has a “TTL Memory Function”, which memorizes the exposure during a TTL Mode shoot, and allows for a one-touch switch to manual mode. You can save time during the strobes setup as the device takes the TTL exposure data, calculates the individual output internally, and transforms the exposure data into manual mode for advance adjustment.

Set your group of strobes free – The Open Mode*4 allowing multiple Air10s to pair with the same group of strobes

The “open mode” allows for multiple Air10s units to pair with the same group of strobes. This means, the need to re-pair devices is eliminated, and even if cameras are changed, the same settings can be used as the shoot continues. This convenient functionality allows multiple cameras and commanders to share a same group of NAS strobes.

Crossover control – Full Control of Different versions of NAS Strobes

Even if your Air 10s is for Sony Mount, it is possible to pair it with Canon, Nikon and other differing version of NAS strobes (i60A, Di700A), and you can retain use of all the functions, including TTL Mode (Applies to the other type of Air10s versions as well).

*1 NAS stands for Nissin Air System, a proprietary wireless TTL communication system developed by Nissin for 2.4GHz radio transmission that allows for stable operation of slave strobes in outdoor or environments that may have other disturbances.

Devices are paired beforehand to ensure stable communication with each other, and to avoid signals from getting mixed up, 8 channels have been set up, providing a secure communication environment.*2 For Canon Mount devices that are set to Mode II, the rear curtain sync function cannot be used.*3 Only supported on i60A. When the device is paired with Di700Aor Air R, the TTL is -2.0~2.0EV, 1/2EV step, in Manual it is 1/1-1/128, 1EV step.*4 When using in Open Mode, the NAS strobe’s firmware needs to be updated.
