In additional K-3 was introduced by Pentax in October 2013. It belongs to the Amateur DSLRs category.
Pentax is well-known and shouldn’t require further introduction, please see our manufacturer’s page for more digital cameras by Pentax.

The 1-Euro coin has a diameter of 23.25mm.
The K-3’s sensor has resolution of 23 megapixel.
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-3 features a mechanism for automatic sensor cleaning.

|Auto Focus Properties|
The K-3’s auto focus processor has 27 AF points. The main point is about that the more points the autofocus has then preferably. If AF has more points then you have a better opportunity to have a focus at the interesting area. In addition, It is a big advantage in a difficult condition. For example, when doing macross.
Manual focusing is available in the Pentax. Even in complicated location.
The K-3 has a built-in flash with a diapason of up to 13m (43 ft.). That range will fit for almost all occasion.
