Pentax WG-10 vs Sony a5100 Sensor Comparison

Normally, it can be hard to visualize the difference between sensor dimensions simply by going over specifications. The image below should give you a more clear sense of the sensor sizes in the WG-10 and a5100.

Plainly, the 2 cameras provide different resolutions and different sensor dimensions. The WG-10 because of its tinier sensor is going to make shooting shallower depth of field tougher and the Sony a5100 will deliver more detail due to its extra 10 Megapixels. Higher resolution can also allow you to crop photographs more aggressively. The more aged WG-10 is going to be disadvantaged when it comes to sensor tech.
