Sigma Announces World’s First F1.8 Constant Aperture Zoom
In a very exciting bit of news for photographers who live and breathe in the low-light world, Sigma today announced a 18-35mm F1.8 DC HSM lens. A constant f/1.8 zoom lens is one and a third stops faster than the f/2.8 lenses that we normally consider a “fast” zooms. Sigma is claiming that their 18-35mm F1.8 DC HSM Art lens is the market’s first zoom lens to achieve a maximum aperture F1.8 throughout the entire zoom range.
The 18-35mm is the latest addition to Sigma’s Art line of lenses, one of their new “Global Vision” products. The Global Vision lenses are categorized by use into one of three groups: Art, Contemporary and Sports. The Art category is supposed to deliver “high-level artistic expression through sophisticated and abundant expressive power.” We’re not sure what “abundant expressive power” means. But if it means fast zoom lenses, we’re all in.
