The E-M10 II was unveiled 19 months later than the A7R which makes the cameras a generation apart from one another. Both of the cameras offer the identical body type (SLR-style mirrorless).

Before going through a thorough comparison, below is a concise synopsis of how the E-M10 II scores against the A7R with respect to portability, imaging, features and an overall rating.

Following is a preview of the gallery photos for Olympus OM-D E-M10 II and Sony Alpha A7R. The full galleries are available at Olympus E-M10 II Gallery and Sony A7R Gallery.

In case you're aiming to carry your camera regularly, you should think about its weight and proportions.

More often than not, it can be tough to visualize the gap between sensor sizing just by reading through specs. The visual here will help give you a clearer sense of the sensor sizing in the E-M10 II and A7R.

As you can plainly see, the 2 cameras offer different resolutions and different sensor sizing. The E-M10 II having a tinier sensor is going to make getting shallower DOF harder and the Sony A7R will resolve greater detail having an extra 20MP. Higher resolution will also let you crop pictures a little more aggressively. The more modern E-M10 II should have an advantage when it comes to sensor technology.
