Sigma sd Quattro H Review

The heart of Sigma sd Quattro H cameras is the Foveon sensor, something that is unique to Sigma, with no other manufacturer featuring a Foveon sensor. (Sigma were so keen on the sensor, that they bought the Foveon company in 2008). The Sigma sd Quattro and H uses the newly developed Foveon X3 direct image sensor .

Due to the sensor design, there is no low pass filter. The previous Sigma SD Merrill series was said to give the equivalent of a 30 megapixel camera from a 15mp (x3) sensor, while the sd Quattro H is said to give the equivalent of a 51 megapixel camera when compared to a Bayer sensor camera, thanks to the 38.5 megapixel sensor (25.7mp + 6.4mp + 6.4mp), and full colour information for each pixel.

Sigma has added a new mode called “Super Fine Detail” – this mode takes a number of pictures, in a uniqueSigma raw file format, and then you need to process this image to export it as a JPEG or the normal Sigma raw file. The mode takes 7 shots for improved dynamic range with low noise. You can’t view the result in camera, and the file is recorded with a .X3I extension. As the camera is taking a number of shots, a tripod is necessary.

If you’ve already read our Sigma sd Quattro review, then you might want to jump to the Performance section of this review, as physically the cameras are very similar, although the Quattro H has added DNG raw support.

The rear of the camera features a 3inch screen, plus a secondary LCD display with camera settings displayed. There is a high-resolution 2.36m dot electronic viewfinder (EVF) with dioptre adjustment, and 0.96x magnification. The camera has the usual P, A, S, and M shooting modes, plus 3 custom shooting modes. The camera does not feature built-in Wi-Fi, nor a video mode.

An optional battery grip, called the Power Grip PG-41 is available. The camera supports tethered shooting with “Sigma Capture Pro” so that you can control the camera from your computer and shoot remotely, for example in a studio setup.

A unique feature of the SD1 / Merrill series was the ability to remove the infrared filter from the camera, and this continues with the sd Quattro H, meaning it’s quick and easy to remove the filter, and use the sq Quattro H for infrared photography (with the correct infrared filter to block visible light).

The sd Quattro H is a large mirrorless camera, bigger than a compact DSLR. With modern styling the camera looks quite different to anything else on the market. It doesn’t feature the typical SLR shape with raised viewfinder triangle, instead the viewfinder is off-set giving the camera a flat(ish) top plate. The flash hot-shoe is in line with the lens mount.

The sd Quattro weighs 635g without the battery or memory card. This is slightly lighter than the Sigma SD1 / Merrill, which weighs 700g, but more than the Sigma dp Quattro cameras, at between 395-500g including the lens.
