Reasons For

10 Reasons For
11.65MP higher megapixel Edit
The Nikon D810 has a megapixel of 36MP, whereas the Pentax K-3 is only a 24.35MP digital camera (11.65MP 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.

30% longer maximum focal length (35mm film equiv) Edit
Nikon D810 is 585mm maximum focal length. That's 171mm longer than the Pentax K-3 (414mm).
14% shorter minimum focal length (35mm film equiv) Edit

A lot wider field of view Edit

67% lighter Edit

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