Leading maker of cameras, lenses and flash units, Sigma Corporation of America, has announced its new compact, high-performance mirrorless camera systems—the Sigma sd Quattro and Sigma sd Quattro H—that uses the Foveon Quattro sensors. The former features an APS-C sized sensor, while the latter touts a bigger APS-H sized sensor for better image quality. According to the manufacturer, both these cameras are designed to take full advantage of all Sigma Global Vision lenses.
Sigma President Mark Amir-Hamzeh said, “With the introduction of these two new cameras, Sigma continues its rich history of innovation. The Foveon sensor is renowned for its imaging characteristics, and the mirrorless interchangeable format offers photographers the full line of Sigma Global Vision lenses to help realize their creative visions. The sharpness of detail and nuanced color tone captured by the Foveon sensors is a key component of Sigma Global Vision. The sd Quattro, and the sd Quattro H, with the newly announced Foveon Quattro APS-H sensor, will be greatly appreciated by photographers who demand the utmost in imaging purity, with the added benefit of portability for both in-studio and on-location photography.”
Both these cameras have the same design aspects with a compact concept, which is consistent with the dp Quattro line and makes them highly portable.
But while the sd Quattro and sd Quattro H are alike in terms of the physical aspect, they are different when it comes to the Foveon sensors that they use. As the sd Quattro uses the same sensor the dp Quattro line uses, its image quality can match that of a 39-megapixel Bayer-pattern sensor in terms of resolution testing. On the other hand, the sd Quattro H sports a bigger APS-H sensor, which means that it can produce images that can match those of a 51-megapixel Bayer-pattern sensor camera in terms of resolution testing. However, they both use the latest Dual TRUE III image processor and the Art, Contemporary and Sport line of lenses, which are created for high megapixel cameras.
