The 1-Euro coin has a diameter of 23.25mm.

The sd Quattro’s image sensor has an effective resolution of around 29 megapixel. The resolution is far above average and will easily be sufficient for years to come. Photos with this resolution can easily be printed in A2 size or larger, even if unwanted parts of the photo have to be cropped.

The Sigma supports taking images in RAW. RAW images are stored as they come from the sensor, without any in-camera processing or sharpening. Converting to JPEG or other formats takes place on the computer, using software like Adobe Lightroom or Sigma’s RAW converter. This involves one extra processing step but almost always results in superior image quality. Some filters, like converting to monochrome (black and white) will only yield decent results when used with RAW images.

The sd Quattro does not have a mechanism for automatic sensor cleaning. Dust that collects on the sensor has to be removed with a blower or brush.

Auto Focus Properties

The sd Quattro’s auto focus processor uses 9 AF points (or sensors). A basic rule of thumb says that the more AF points you have, the better. More AF points mean a better chance to have a point at the location of interest in a scene, a big plus in challenging situations (e.g. when panning the camera).

Manual focus is also possible with the Sigma, a plus in tricky situations or for some creative freedom.

Flash Specs

The sd Quattro doesn’t feature a built-in flash. That is not unsusual in this camera category.

A flash or a trigger for remote flashes can be attached to the Sigma’s hotshoe.

Display Specs

The sd Quattro features a monitor with a diagonal of 76.00mm (3.0 in.) and a resolution of c. 1.62 megapixel. A resonable value that will make it easy to evaluate images directly in-camera.

Unfortunately, the sd Quattro’s monitor is not articulated. That can make it tricky to frame your subject in some situations, e.g. when taking selfies.

The sd Quattro does not feature a touch screen.
