Sigma is known by the photographers as one of the
manufactures that produce most complete lenses for various brands. But in
recent years, Sigma has also experimented with its own cameras, especially in
the Sigma DP Quattro line.
Now Sigma continues to develop its innovative in photography
through its first two mirrorless cameras: sd Quattro and sd Quattro H. Both are
wearing Foveon sensor that's quite unique. It’s unique because this sensor
basically consists of a number of layers, allowing the camera to capture images
with richer colors and higher resolution than image sensor technology in
general.
Sigma sd Quattro and sd Quattro H have the exact same
design, the difference lies only on the size of sensor used: the sd Quattro
packs an APS-C sensor, while the sd Quattro H has APS-H sensor which is about
30 percent larger.
The sd Quattro sensor has a resolution of 19.6 megapixels,
while the sd Quattro H sensor has 25.5-megapixel resolution, each with a hybrid
autofocus system. But because the technology used by the Foveon sensor is
unique, each sensor has a resolution that's equivalent with 39 megapixels and
51 megapixels on the Bayer sensor that's used by almost all digital cameras
today.
In addition to the use of a unique sensor technology, the
design of these two sd Quattro is also interesting. The hand grip is shorter
than the body part which packs the sensor. This is because Sigma wants the
design of these two cameras can be compatible with the entire line of Sigma
lenses, including the lenses for DSLR cameras. As a result, the 'house' of the
lens must be made larger.
At the rear, the user will see the 2.3 million dots
electronic viewfinder, with viewing angle close to 100 percent, according to
Sigma claim. Underneath, there is a 3-inch LCD with a resolution of 1.62
million dots. Uniquely, this LCD is actually made up of two screens; small
screen on the right will display the camera settings constantly. All of this is
packaged in a magnesium body which's resistant to dust and waterproof.
So far there is no information about the price and
availability of these cameras. Sigma is exhibiting both of them to the visitors
of CP + 2016 event that's held in Yokohama, Japan.
