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

The Alpha A7’s sensor has resolution of 24 megapixel.

The Sony 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 Sony’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 Alpha A7 features a mechanism for automatic sensor cleaning.

Auto Focus Properties

The Alpha A7’s auto focus processor uses 117 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 Sony, a plus in tricky situations or for some creative freedom.
