Olympus E-300 vs Sony G3

Below, we will be evaluating the Olympus E-300 versus Sony G3, one is a Advanced DSLR and the latter is a Small Sensor Compact by rivals Olympus and Sony. The image resolution of the E-300 (8MP) and the G3 (10MP) is relatively well matched but the E-300 (Four Thirds) and G3 (1/2.3") use different sensor sizing.

The E-300 was introduced 5 years prior to the G3 which is quite a significant gap as far as tech is concerned. Both cameras come with different body type with the Olympus E-300 being a Mid-size SLR camera and the Sony G3 being a Compact camera.

Before getting through a complete comparison, below is a quick introduction of how the E-300 scores vs the G3 in terms of portability, imaging, features and an overall score.

Often, its hard to imagine the gap between sensor sizes only by checking a spec sheet. The image below will help provide you a far better sense of the sensor sizing in the E-300 and G3.

As you can see, both of those cameras have got different resolutions and different sensor sizes. The E-300 using its bigger sensor is going to make getting shallow DOF easier and the Sony G3 will resolve extra detail using its extra 2 Megapixels. Higher resolution will also enable you to crop pictures much more aggressively. The more aged E-300 is going to be disadvantaged in sensor tech.
