Super high-res mirrorless from Sigma

Sigma has announced a new mirrorless APS-C format camera, the sd Quattro arriving in Australia later this month at an RRP of $1199, along with the powerful Sigma EF-630 flash for Sigma mount, with an RRP of $549. (With Canon and Nikon mounts to come.)

The sd Quattro/f1.4 30mm Art bundle represents great value at $1599.
The Sigm sd Quattro/f1.4 30mm Art bundle represents great value at $1599.

The sd Quattro will also be offered as a bundle with the highly-rated Sigma 30mm 1.4 DC HSM Art lens for $1599 – a great buy given the 30mm f1.4 ‘Art’ lens alone has an RRP of $700!

The sd Quattro utilises Sigma’s proprietary Foveon Quattro sensor which delivers a resolution equivalent to 39 megapixels using a conventional Bayer-pattern sensor, according to Sigma. The 29-megapixel APS-C Foveon X3 Quattro CMOS sensor uses a unique stacked design to deliver full colour information at every single pixel without interpolation. Using a 1:1:4 RGB pixel ratio (hence the ‘Quattro’ tag), eliminates the need for an optical low-pass filter.

The camera has a rugged magnesium alloy body which is dust- and splashproof. The unique design features a comfortable grip and physical controls designed for intuitive control. There is a Quick Set button near the shutter that instantly brings up the Quick Set Menu for access to commonly used settings in the viewfinder.

Two-mode AF combines Phase detection for focus speed and Contrast detection for accuracy. Focus settings have also been enhanced with modes such as Movement Prediction, Face Detection, Free Movement, Focus Peaking and others.

The super-sharp 2.3 megapixel viewfinder displays close to 100 percent field of view, and in ‘Auto’ will toggle between the viewfinder when the user has the camera to their eye and the 3-inch, 1.62 million dot LCD when the user lowers the camera.

There is also a smaller LCD screen displaying exposure information for constant access to critical settings.

A new ‘Super-Fine Detail’ mode captures seven different exposures with one shot and merges them for exceptional dynamic range.

Continuous shooting is at up to 3.6 fps at top quality for 14 frames.

Other Features
– With a 39-megapixel equivalent resolution, the dp Quattro can produce JPEG images of 7680 x 5120 pixels;

Sigma EF-630 flash
The $549 EF-630 features TTL exposure control, high-speed sync, wireless flash functions, rear-curtain sync, auto-zoom and wide-angle illumination coverage.

The FP Flash function makes flash photography possible at shutter speeds greater than the normal 1/250 sec sync speed – useful when setting a larger aperture to limit depth of field when shooting in daylight.

– Slave flash function for use with multiple flash systems;
– Modeling flash function;
