Reasons For

6 Reasons For
Significantly higher megapixel Edit
The Pentax 645Z has a megapixel of 51.4MP, whereas the Samsung NX30 is only a 20.3MP digital camera (31.1MP lower). Read more

The resolution of the images a digital camera produces is measured in megapixels (MP). One megapixel is equal to 1 million pixels and is a result of the pixel width multiplied by the pixel height of the image. While a higher image resolution generally results in sharper images, only a relatively low megapixel count is required when printing the image at a small size or to display it on a computer screen.

A sensor with more megapixels will be able to capture more detailed photos and the image will appear sharper. Images with more megapixels can also be printed at a larger size.

Significantly smaller maximum aperture number Edit
The Pentax 645Z is a 22 maximum aperture digital camera, whereas the Samsung NX30 is only a 6.3 maximum aperture digital camera (15.7 bigger).
0.2" larger display diagonal Edit
The Pentax 645Z is a 3.2" screen digital camera, whereas the Samsung NX30 is only a 3" screen digital camera (0.2" smaller). Read more

The display diagonal is the size the size of the screen integrated in to the back of the camera. A larger display diagonal makes it easier to see if a shot has turned out as intended. Pocket cameras have smaller display diagonals as full size digital SLRs.
