Sony A7R vs Sony A6400

Below, we will be matching up the Sony A7R versus Sony A6400, one being a Pro Mirrorless and the latter is a Advanced Mirrorless and both are manufactured by Sony. There exists a significant gap between the image resolutions of the A7R (36MP) and A6400 (24MP) and the A7R (Full frame) and A6400 (APS-C) use different sensor measurements.

The A7R was revealed 5 years earlier than the A6400 and that is quite a sizable gap as far as technology is concerned. Both cameras come with different body type with the Sony A7R being a SLR-style mirrorless camera and the Sony A6400 being a Rangefinder-style mirrorless camera.

Before going straight into a full comparison, below is a concise introduction of how the A7R grades versus the A6400 for portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Sony Alpha A7R and Sony Alpha a6400. The full galleries are provided at Sony A7R Gallery and Sony A6400 Gallery.

If you are aiming to lug around your camera, you're going to have to take into account its weight and dimensions.

Remember, the weight of an Interchangeable Lens Camera will change dependant on the lens you are using at the time. Underneath is the front view dimension comparison of the A7R versus the A6400.

Using dimensions and weight, the portability grade of the A7R and A6400 is 78 and 83 respectively.

Quite often, its hard to imagine the gap between sensor measurements purely by reading technical specs. The photograph here may give you a greater sense of the sensor sizes in the A7R and A6400.

As you have seen, the two cameras have got different megapixels and different sensor measurements. The A7R using its bigger sensor is going to make achieving shallow DOF simpler and the Sony A7R will offer greater detail because of its extra 12MP. Higher resolution will also allow you to crop photographs much more aggressively. The older A7R is going to be disadvantaged in sensor tech.
