Reasons For

9 Reasons For
26% higher megapixel Edit
The Olympus OM-D E-M1 is a 16.3MP digital camera. That's 4.1MP higher than the Sony Alpha A7S II (12.2MP). 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.

27% more total megapixels Edit
The Olympus OM-D E-M1 is a 16.8MP digital camera. That's 4.4MP more than the Sony Alpha A7S II (12.4MP).
800.00 auto Focus (AF) pointss Edit
