Sony RX10 vs Sony A77

Let's look a little more in depth at the Sony RX10 versus Sony A77, one being a Large Sensor Superzoom and the other is a Advanced DSLR and they are both sold by Sony. The resolution of the RX10 (20MP) and the A77 (24MP) is fairly comparable but the RX10 (1") and A77 (APS-C) possess different sensor sizing.

The RX10 was revealed 2 years later than the A77 and that is a fairly big gap as far as camera technology is concerned. The two cameras offer different body type with the Sony RX10 being a SLR-like (bridge) camera and the Sony A77 being a Mid-size SLR camera.

Before we go through a detailed comparison, below is a short summation of how the RX10 scores versus the A77 with regard to portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Sony Cyber-shot DSC-RX10 and Sony SLT-A77. The full galleries are viewable at Sony RX10 Gallery and Sony A77 Gallery.

When you are aiming to lug around your camera, you should factor in its weight and dimensions.

More often than not, its hard to visualize the difference in sensor measurements purely by checking out a spec sheet. The graphic underneath will help offer you a better sense of the sensor sizing in the RX10 and A77.

Clearly, each of the cameras offer different megapixels and different sensor measurements. The RX10 using its smaller sensor is going to make shooting shallow DOF trickier and the Sony A77 will provide more detail because of its extra 4 Megapixels. Greater resolution can also allow you to crop images a little more aggressively. The fresher RX10 should have an advantage in sensor technology.
