Sigma Releases New 24mm Art Lens, DP Quattro Series Camera






pphoto_dp0_quattro_side_slanting-large-2Sigma announced the fourth member of its DP Quattro series of digital cameras, plus a new 24mm Art lens in advance of the CP+2015 show in Japan.

The DP0 sports a fixed 14mm F4 lens (21mm, 35mm equivalent). All other features will be identical to the previous models in the lineup.

The DP0 incorporates a 29-megapixel APS-C-sized Foveon X3 Quattro image sensor. The Quattro sensor features a proprietary three-layer design meant to replicate how film emulsions capture red, green and blue light. Working in tandem, these three layers create Sigma’s equivalent of a 39-megapixel image, and Sigma’s True III image processor crunches the data to output an image that the company claims delivers truer-to-life colors and more realistic images than competing sensor designs.

Beyond the sensor, the DP0 delivers 14-bit RAW image capture and a sensitivity range of ISO 100 to 6400. The body design marries a thin, panoramic frame with a prominent grip that extends from the back of the camera, giving the DP0 a particularly distinctive look.

Pricing and availability on the DP0 were not announced.


401_24mm_art-150dpi-angledSigma also announced a new member of its Art lens family. The new 24mm F1.4 Art  lens is designed for full-frame DSLRs. It features  nine rounded aperture blades and a maximum magnification of 1:5.3. The  minimum focusing distance is 9.8 inches.

The lens incorporates both “F” Low Dispersion (FLD) glass and Special Low Dispersion (SLD) glass in  15 elements in 11 groups. According to Sigma, this construction minimizes chromatic aberration of magnification especially in the edge of the image field.

By placing aspherical elements in the rear of the lens, Sigma said it was able to improve performance when shooting wide open, keeping distortion, flare and chromatic aberration to a minimum.

A full-time manual focusing mechanism lets you switch into manual focusing during autofocus by rotating the lens ring.

Pricing and availability for the new 24mm Art Lens were not announced.

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.
