Sigma unleashes two new mirrorless cameras with Foveon X3 sensors and dual-screen LCD

In addition to the lenses Sigma revealed earlier today, the Japanese electronics company also announced two new mirrorless cameras and a dedicated speedlight.

Taking inspiration from the company’s DP Quattro cameras, the sd Quattro and sd Quattro H drop the fixed lens for a Sigma SA mount, all while keeping Sigma’s signature Foveon Quattro sensor technology at the heart of the cameras.

The difference between the two cameras lies in the size of the sensor. The sd Quattro H uses a 45MP APS-H sensor, while the sd Quattro contains a 29-megapixel APS-C sensor. Sigma claims these sensors offer the resolution and image quality well above their rated megapixel level, with the APS-C Foveon said to be the equivalent of a 39-megapixel sensor in a standard camera and the APS-H said to be equal to a 51-megapixel sensor.

The sensor inside both the sd Quattro H and sd Quattro are capable of putting out uncompressed RAW photos at 3.8 frames per second and 3.6 frames per second, respectively, thanks in part to the Dual TRUE III Imaging Processing Engine.

For getting photos in focus, the sd Quattro H and sd Quattro both use a 9-point hybrid autofocus system that relies on phase detection for speed and contrast detection for accuracy.

For composing and reviewing images, Sigma has included a 2.36 million-dot electronic viewfinder with almost 100% field of view as well as a unique two-piece 3-inch 1.62 million-dot LCD screen on the back that separates the settings module from the composition and reviewing side of the screen, much like the LCD display seen atop many DSLRs.

As you’ve probably noticed by now, both mirrorless cameras take design queues from their DP Quattro predecessor, with unique curves, sharp features and an all-round conceptual form factor.

Considering Sigma opted for their SA lens mount, these cameras will be able to use all 19 lenses in Sigma’s growing collection of Global Vision lenses.

There’s no word yet on pricing or availability, but you can still sign up to be notified when the sd Quattro H and sd Quattro go on sale.

Announced alongside the cameras is Sigma’s new EF-630 electronic flash.

Designed to work alongside Canon, Nikon and Sigma cameras, the EF-630 overs TTL exposure control, wireless flash, high-speed sync, auto-zoom and a built-in Wide Panel for broader coverage. It uses a dot matrix LCD screen and directional buttons for operation and controlling through the menu system. Like its lens counterparts, the EF-630 will be able to have its firmware updated via Sigma’s Optimization Pro software and Flash USB Dock.
