The E-300 was released 4 years before the A300 which is quite a large gap as far as technology is concerned. Both the cameras have different body design with the Olympus E-300 being a Mid-size SLR camera and the Sony A300 being a Compact SLR camera.

Before diving right into a in-depth comparison, here is a simple introduction of how the E-300 grades vs the A300 in the way of portability, imaging, features and an overall mark.

Following is a sample of the gallery pictures for Olympus E-300 and Sony Alpha DSLR-A300. The complete galleries are provided at Olympus E-300 Gallery and Sony A300 Gallery.

For those who are aiming to travel with your camera regularly, you'll have to consider its weight and measurements.

Keep in mind, the weight of an Interchangeable Lens Camera will differ depending on the lens you choose at that moment. Below is a front view sizing comparison of the E-300 and the A300.

Taking into consideration dimensions and weight, the portability score of the E-300 and A300 is 67 and 64 respectively.

Typically, it is difficult to visualise the gap between sensor dimensions only by checking specs. The picture here will help give you a better sense of the sensor measurements in the E-300 and A300.

All in all, both cameras provide different megapixels and different sensor dimensions. The E-300 because of its tinier sensor will make achieving shallower DOF harder and the Sony A300 will resolve greater detail as a result of its extra 2MP. Greater resolution will make it easier to crop photos more aggressively. The more aged E-300 is going to be behind in sensor innovation.
