Canon SX620 HS vs Panasonic GH4

Let's look much closer at the Canon SX620 HS and Panasonic GH4, former being a Small Sensor Superzoom while the latter is a Pro Mirrorless by competitors Canon and Panasonic. There is a sizable difference among the sensor resolutions of the SX620 HS (20MP) and GH4 (16MP) and the SX620 HS (1/2.3") and GH4 (Four Thirds) posses different sensor sizing.

Often, it is very tough to picture the difference in sensor sizing simply by viewing technical specs. The graphic below will provide you a stronger sense of the sensor sizing in the SX620 HS and GH4.

As you have seen, the 2 cameras have different megapixel count and different sensor sizing. The SX620 HS with its smaller sensor is going to make achieving shallow DOF more challenging and the Canon SX620 HS will result in more detail because of its extra 4MP. Higher resolution will also allow you to crop pictures a bit more aggressively. The younger SX620 HS should have a benefit with regard to sensor technology.
