Sigma Announces Lens Mount Conversion Service (and 4-year warranty)

Sigma18_35MountIf you’ve considered changing up your camera system but are too heavily invested in lenses to do so, Sigma may have the perfect solution to break the bond you have to one brand or another. That is, if your optical stash includes lenses from Sigma’s Global Vision line.

Beginning September 2, 2013, Sigma Corporation of America will offer a fee-based lens mount conversion service for its Global Vision lenses. As the name implies, the company will change out the current mount for a mount of your choice, as long as Sigma makes that particular lens for the mount requested. DSLR mounts include Canon, Nikon, Pentax, Sigma and Sony. But Sigma hasn’t forgotten about the mirrorless interchangeable lens camera users among us, who can have their lenses converted to Micro Four Thirds or Sony E-mounts (again, as long as the requested lenses are currently available with those mounts).

The full story is now on PDNOnline’s Gear page.

Sigma Announces World’s First F1.8 Constant Aperture Zoom

PPhoto_A_18_35_013_VerticalIn 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.
