Olympus SP-620 UZ vs Panasonic GH3

Here is a thorough comparison of the Olympus SP-620 UZ versus Panasonic GH3, one being a Small Sensor Superzoom and the latter is a Advanced Mirrorless by brands Olympus and Panasonic. The sensor resolution of the SP-620 UZ (16MP) and the GH3 (16MP) is relatively comparable but the SP-620 UZ (1/2.3") and GH3 (Four Thirds) posses totally different sensor dimensions.

The SP-620 UZ was announced 8 months prior to the GH3 which means that they are both of a similar generation. Both the cameras have different body design with the Olympus SP-620 UZ being a Compact camera and the Panasonic GH3 being a SLR-style mirrorless camera.

Before delving straight to a in depth comparison, here is a brief summation of how the SP-620 UZ grades against the GH3 when it comes to portability, imaging, features and an overall rating.

Don't forget, the weight of an Interchangeable Lens Camera will differ dependant on the lens you have at that moment. Following is a front view proportions comparison of the SP-620 UZ against the GH3.

Considering dimensions and weight, the portability score of the SP-620 UZ and GH3 is 78 and 66 respectively.

More often than not, it's difficult to visualise the gap in sensor sizing only by going through technical specs. The visual here should provide you a clearer sense of the sensor sizes in the SP-620 UZ and GH3.

As you can tell, the 2 cameras provide the same megapixels albeit not the same sensor sizing. The SP-620 UZ uses the smaller sensor which should make getting shallower depth of field more challenging. The older SP-620 UZ will be disadvantaged with regard to sensor innovation.
