Canon 6D vs Pentax K-3 III Sensor Comparison

Sometimes, it is very tough to visualize the contrast in sensor sizing purely by looking through specifications. The photograph below might offer you a stronger sense of the sensor measurements in the 6D and K-3 III.

Plainly, each of these cameras offer different megapixel count and different sensor sizing. The 6D using its larger sensor is going to make achieving shallow depth of field less difficult and the Pentax K-3 III will provide you with greater detail because of its extra 6 Megapixels. Greater resolution will also allow you to crop pics a little more aggressively. The older 6D will be behind when it comes to sensor innovation.
