4 Reasons For
66% higher megapixel count Edit
The Sigma DP2 Merrill is a 46MP digital camera. That's 29.95MP higher than the Panasonic Lumix DMC-GH4 (46MP). 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.

65% more total megapixel count Edit
The Sigma DP2 Merrill is a 48MP digital camera. That's 30.8MP more than the Panasonic Lumix DMC-GH4 (48MP).
0.7 smaller minimum aperture Edit
The Sigma DP2 Merrill has a minimum aperture of 2.8, however the Panasonic Lumix DMC-GH4 is a 3.5 minimum aperture digital camera (0.7 larger).
A lot lighter Edit
The Sigma DP2 Merrill has a weight of 330g, but the Panasonic Lumix DMC-GH4 is a 480g digital camera (150g heavier). 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.
