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

The A99 II’s image sensor has an effective resolution of around 42 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 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 A99 II does not have a mechanism for automatic sensor cleaning. Dust that collects on the sensor has to be removed with a blower or brush.
