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

The DMC GH4’s image sensor has an effective resolution of around 16 megapixel. That’s roughly average and will be sufficient for most purposes. Photos with this resolution can easily be printed to A3 or A2 size.

The Panasonic 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 Panasonic’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 DMC GH4 features a mechanism for automatic sensor cleaning.

Auto Focus Properties

The DMC GH4’s auto focus processor uses 49 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 Panasonic, a plus in tricky situations or for some creative freedom.
