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

The K-1 II’s image sensor has an effective resolution of around 36 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 Pentax 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 Pentax’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 K-1 II features a mechanism for automatic sensor cleaning.

Auto Focus Properties

The K-1 II’s auto focus processor uses 33 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. in sports).

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