6 Reasons For
20% higher megapixel count Edit
The Pentax K-S1 has a megapixel count of 20.12MP, however the Pentax K-50 is only a 16.28MP digital camera (3.84MP 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.

3.91MP more total megapixel count Edit
The Pentax K-S1 has a total megapixel count of 20.4MP, whereas the Pentax K-50 is only a 16.49MP digital camera (3.91MP less).
0.03x higher lens magnification ratio Edit
The Pentax K-S1 has a lens magnification ratio of 0.95x, but the Pentax K-50 is only a 0.92x lens magnification ratio digital camera (0.03x lower). Read more

The lens magnification ratio is the ratio between the true size of the object being photographed and the size of the object when projected on to the camera's sensor.

A higher lens magnification ratio is important for macro photography as it allows you to focus on very small object very close to the lens.

HDMI port Edit
The Pentax K-S1 has an HDMI port, whereas the Pentax K-50 does not. Read more

A HDMI (High-Definition Multimedia Interface) port is an interface to transfer audio and video data between devices such as digital cameras, computer monitors, TVs and projectors.

A HDMI port on the camera allows you to connect the camera directly to a compatible TV for easy playback of your photos.

92g lighter Edit
The Pentax K-S1 is a 498g digital camera. That's 92g lighter than the Pentax K-50 (498g). Read more

The camera's weight will depend on the type and size of camera. Compact cameras are usually the lightest while digital SLRs will be heavier. Also consider the number and weight of lenses to take when using a SLR.

The lower the camera weight, the easier it will be to carry around and it will also reduce your hand luggage weight when flying.

£3 cheaper
The Pentax K-S1 costs £279.80, whereas the Pentax K-50 is £283.00.
