Ronkonkoma, N.Y. — Sigma announced Monday offerings in its new “dp Quattro” Foveon-sensor-based compact camera series as part of its 2014 camera lineup.
New models include three dp Quattero models: the dp1, dp2 and dp3. Pricing and ship dates have not yet been announced, but Sigma said the dp2 Quattro will be the first camera released in the group.
This TWICE webinar, hosted by senior editor Alan Wolf, will take a look at what may be the hottest CE products at retail that will be sold during the all-important fourth quarter. Top technologies, market strategies and industry trends will be discussed with industry analysts and executives.
Ronkonkoma, N.Y. — Sigma of America said Monday that it is releasing a Geometrical Modulation Transfer Function (MTF) chart and a Diffraction MTF chart for use in measuring the performance of all of its new Global Vision lenses.
The company said MTF charts are important because they help photographers better understand the optical quality of its lenses.
Sigma has traditionally released Diffraction MTF data because it takes the diffraction quality of light into consideration, which can dramatically affect the data outcome.
Ronkonkoma, N.Y. – Sigma revealed Tuesday that a free firmware upgrade is available for photographers using Nikon mount Sigma lenses with their Nikon model D5300 cameras.
The company said it has discovered that when paired with the D5300, Sigma Nikon mount lenses containing internal motors do not properly operate the optical stabilization (OS) and Live View Auto Focus functions.
The issue is specific to lenses used with this particular camera.
Ronkonkoma, N.Y. – Sigma introduced Wednesday a 24-105mm F4 DG OS HSM full-frame “Sigma Art Lens” designed for artistic expression and image quality.
Sigma’s lens combines a basic wide to medium tele zoom range with an inner focusing system that eliminates front lens rotation, to enhance stability while allowing the use of circular polarizing filters, Sigma said.
Ronkonkoma, N.Y. — Sigma America introduced a new service on Thursday that enables the company’s Global Vision lens owners to change lens mounts for use on different camera systems.
Sigma also announced it is extending the warranty on all of its products — including cameras, lenses and flashes purchased on or after July 1 — to four years.
Ronkonkoma, N.Y. — Sigma Friday said its previously announced 18-35mm F1.8 DC HSM Art lens will ship to dealers in early July at a $799 suggested retail.
The lens is billed as “the market’s first zoom lens to achieve a maximum aperture of F1.8 throughout the entire zoom range,” and was created for DSLR cameras with APS-C-size sensors.
Ronkonkoma, N.Y. — Sigma introduced Thursday a 60mm F2.8 DN Art lens for mirrorless compact system cameras, adding a new focal length in the company's lineup for both Micro Four Thirds and Sony E-mount cameras.
Sigma's 60mm F2.8 DN Art lens will hit shelves mid-May at a $239 estimated street price.
First revealed at the CP+ Camera and Photo Imaging Show in Japan earlier this year, the 60mm F2.8 joins Sigma’s other DN lenses for mirrorless compact system cameras — the 19mm F2.8 DN and the 30mm F2.8 DN.
Ronkonkoma, N.Y. – Sigma introduced Thursday what it is calling the first F1.8 constant aperture zoom lens.
Sigma’s 18-35mm F1.8 DC HSM (pricing to be announced later) is the latest addition to the company’s Art line of lenses, designed under the new Global Vision.
The lens was created for DSLR cameras with APS-C size sensors, which translates to a focal range of 27-52.5mm on a 35mm camera.
Ronkonkoma, N.Y. — Sigma introduced Thursday its Sigma Photo Pro 5.5 software, which includes upgrades and updates for both Mac and Windows platforms, as well as a new Monochrome Mode processing interface.
The updated software is now available to download in both Mac and Windows versions.
Sigma said the new Monochrome Mode features several new functions, including a channel-mixing palette, which allows users to control the level of red, green and blue within an image for better tonal separation and contrast.
Yokohama, Japan — Sigma of America introduced Tuesday four lenses for its ART product line, including three lenses for mirrorless interchangeable lens cameras and one APS-C DSLR model.
The Sigma lenses include the 30mm F1.4 DC HSM, which will be available in Sigma, Canon and Nikon mounts, and the 30mm F2.8 DN, 19mm F2.8 DN and 60mm F2.8 DN lenses, which are available for both Micro Four Thirds and Sony E-Mount camera systems.
Pricing and availability on all of lenses will be announced later.
