10 Reasons For
9.7MP higher megapixel count Edit
The Sigma SD1 Merrill is a 46MPMP digital camera. That's 9.7MP higher than the Nikon D810A (46MPMP). 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.

More total megapixel count Edit
The Sigma SD1 Merrill is a 48MPMP digital camera. That's 10.91MP more than the Nikon D810A (48MPMP).
Smaller minimum ISO speed Edit
The Sigma SD1 Merrill is a 100 minimum ISO speed digital camera. That's 100 smaller than the Nikon D810A (100).
27% higher lens magnification ratio Edit
The Sigma SD1 Merrill is a 0.95xx lens magnification ratio digital camera. That's 0.25x higher than the Nikon D810A (0.95xx). 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.

A little bigger eye relief Edit
The Sigma SD1 Merrill has an eye relief of 18mmmm, however the Nikon D810A is only a 17mm Eye relief digital camera (1mm smaller). Read more

Eye relief (also known as eye point) refers to how far away from the eye piece your eye can be and you can still see the full frame of the image that will be taken.

A larger eye relief distance is useful for people who wear glasses, meaning that they can't put their eye directly on the eye piece.

180g lighter Edit
