I featured works by Mike Olbinski in the past (1 and 2), and here is another stunning video by him. Monsoon III is a 7 minutes time-lapse of the North American Monsoon.

Olbinski spent 35 days and shot over 85,000 frames to produce the video. He used a Canon EOS 5Ds R, two EOS 5D Mark III, EF 11-24mm f/4L, EF 16-35mm f/2.8L II USM, 35mm, 50mm and 135mm lenses. Processed using Lightroom, LR Timelapse, After Effects and Premiere Pro.

Sigma press release:

Outstanding optical performance, ultra-wide zoom range, and versatile flagship sports lens headline the Sigma line-up at Photokina 2016

Cologne, Germany – September 19, 2016 – Sigma Corporation of America, a leading camera, DSLR lens, flash and accessories manufacturer, unveiled its new 85mm F1.4 DG HSM Art, 12-24mm F4 DG HSM Art and 500mm F4 DG OS HSM Sport Global Vision lenses at the Photokina 2016 event (hall 4.2, stands B020, B028 and C029).

“We are thrilled to announce three state-of-the-art additions to the Global Vision line. The Sigma 85mm 1.4 Art has been a highly requested lens and we are very confident those customers who have been waiting for us to deliver this lens will be more than pleased with the superior optical performance and zero compromise,” states Mark Amir-Hamzeh, president of Sigma Corporation of America. “In addition, the re-engineered 12-24mm F4 and highly competitive 500mm F4 Sport lens both embody the world-class performance our Global Vision lenses are known for. We look forward to seeing the incredible images our customers will create using these new Sigma lenses.”

Sigma 85mm F1.4 DG HSM Art – The Ultimate Portrait Lens
Delivering the ultimate in creative expression, the new Sigma 85mm F1.4 Art lens is engineered to support the highest resolution sensors on the market with an exceptional degree of sharpness. The high-performance optical system is purpose-built by Sigma R&D to produce the attractive bokeh effect sought after by discerning photographers. The lens’ advanced architecture features two SLD (special low dispersion) glass elements and one glass element with a high rate of anomalous partial dispersion and refraction. A re-engineered AF system brings 1.3X the torque of its predecessor, while other features such as a full-time manual focus override have been added, which can be controlled when the focus ring is rotated, even during continuous AF.

The Sigma 85mm F1.4 DG HSM Art lens supports Canon, Nikon and Sigma mounts. The Nikon mounts feature a brand new electromagnetic diaphragm.

The Sigma 85mm F1.4 Art lens will be available in late October and retails for a recommended street price of $1199.00 USD.

Sigma 12-24mm F4 DG HSM Art Ultra-Wide Angle Zoom for the Era of Ultra-High Resolution Digital Cameras
Boasting the renowned Global Vision image quality from center to edge, the new Sigma 12-24mm F4 features the largest aspherical glass mold in the industry, offering photographers an ultra-wide angle zoom with virtually no distortion, flare or ghosting. Encompassing the long history of Sigma wide angle lens development expertise, the new 12-24mm F4 performance highlights include constant F4 brightness and the brand new Sigma AF system with 1.3X torque boost. The 12-24mm F4 features lens elements made with FLD (“F” Low Dispersion) glass, which is equivalent to calcium fluorite in performance. Combined with an optimized power distribution, the result is outstanding image quality from center to edges. With a minimum focus distance of 9.4 inches at 24mm, photographers can compose incredible close-up shots with expansive backgrounds.

The all new Sigma 12-24mm F4 DG HSM Art lens supports Canon, Nikon and Sigma mounts. The Nikon mounts feature the brand new electromagnetic diaphragm.

The Sigma 12-24mm F4 Art lens will be available in late October and retails for a recommended street price of $1599.00 USD.

Sigma 500mm F4 DG OS HSM Sport Lens – Pro Fast-Aperture Prime Super Telephoto
The flagship Sigma super telephoto 500mm F4 Sport lens incorporates the very latest in Sigma optical technology and innovation. Designed for the professional sports and wildlife shooter, the ultra-durable lens features magnesium alloy components, a carbon fiber hood, a water and oil resistant front element, and is dust and splash proof. The 500mm F4 features a drop-in rear filter slot for polarizers, UV and other critical filters. To help prevent damage during shooting and maintenance, the lens is also compatible with the exclusive SIGMA Protector LPT-11 (sold separately).

The lens incorporates two FLD and one SLD glass elements, while the optimized power distribution helps minimize spherical aberration and axial chromatic aberration. The optical system also effectively minimizes transverse chromatic aberration, which can affect the edges of the shots taken in the telephoto range. In addition, image quality remains exceptional when the lens is used with a Sigma Telephoto Converter (sold separately).

Other key performance features include Sigma’s two-mode Optical Stabilizer for enhanced performance when shooting handheld for still subjects or panning and tracking for moving subjects. There is also a customizable AF “return” function for setting the focus position of one’s choice and returning to that preset distance.

The all new Sigma 500mm F4 supports Canon, Nikon and Sigma mounts. The Nikon mounts feature the brand new electromagnetic diaphragm.

The Sigma 500mm F4 Sport lens, in Canon and Sigma mounts, will be available in late October. The Nikon mount will be available in late November. The 500mm F4 will retail for a recommended street price of $5999.00 USD.

All Sigma Global Vision lenses, including the new 85mm F1.4 DG HSM Art, 12-24mm F4 DG HSM Art, and 500mm F4 DG OS HSM Global Vision lenses, can be updated with the latest lens firmware from a workstation or laptop using the Sigma Optimization Pro software and Sigma USB Dock (sold separately).

Tested for Optimum Performance
Sigma lenses are born of well thought-out design concepts, exceptional Japanese craftsmanship and manufacturing, and advanced lens performance testing and evaluation. To this end, Sigma has developed its own A1 proprietary MTF (modulation transfer function) measuring system using 46-megapixel Foveon direct image sensors. Even the most elusive high-frequency details are within the scope of Sigma’s quality control inspections. Every Global Vision lens is A1 tested, analyzed and approved before leaving the factory, ensuring maximum performance out of the box.

Canon EF 11-24mm f/4L DxOMarked (the lens is a champ)

DxOMark tested the Canon EF 11-24mm f/4L, the company’s latest ultra-wide angle lens, and a lens that only gets highest regards. Not a budget lens, the EF 11-24mm f/4L sells at $3,000.

In the conclusion:

While traditionally strong in its telephoto lineup, Canon has always been rather weak in offering a range of ultra-wide-angle lenses. When introduced a few years ago, the EF 8-15mm f4L USM Fisheye zoom helped redress the balance, but it didn’t go far enough. Now with this new lens, Canon has proved it can compete with its long-term rival Nikon as well as with new challengers, such as Sigma, who offer some very specialized models at accessible prices. Sure, the EF 11-24mm f4L USM lacks the fast f2.8 aperture of the Nikon, but Canon traded that for wider coverage and didn’t make any concessions with image quality. Even the price is relatively accessible. Read the test report at DxOMark.

EF 11-24mm f/4L

  • EF Mount L-Series Lens/Full-Frame Format
  • Constant f/4 Maximum Aperture
  • Super UD, UD, and 4 Aspherical Elements
  • SWC, Air Sphere, and Fluorine Coatings
  • Ring-Type USM Autofocus Motor
  • Internal Focus; Full-Time Manual Focus
  • Weather-Resistant Design
