Nikon P300 vs Sony A7S III

Below is a comprehensive review of the Nikon P300 and Sony A7S III, one being a Small Sensor Compact and the latter is a Pro Mirrorless by manufacturers Nikon and Sony. The sensor resolution of the P300 (12MP) and the A7S III (12MP) is relatively close but the P300 (1/2.3") and A7S III (Full frame) enjoy different sensor measurements.

The P300 was introduced 10 years before the A7S III and that is a fairly significant gap as far as camera tech is concerned. The two cameras offer different body type with the Nikon P300 being a Compact camera and the Sony A7S III being a SLR-style mirrorless camera.

Before getting straight into a detailed comparison, below is a concise overview of how the P300 grades against the A7S III in the way of portability, imaging, features and an overall grade.

For anybody who is aiming to lug around your camera frequently, you should factor in its weight and measurements.

Remember, the weight of an Interchangeable Lens Camera will vary depending on the lens you have at that moment. The following is the front view physical size comparison of the P300 versus the A7S III.

Taking into account size and weight, the portability score of the P300 and A7S III is 92 and 61 respectively.

Oftentimes, it's difficult to visualize the contrast in sensor measurements only by researching a spec sheet. The graphic below will offer you a far better sense of the sensor sizing in the P300 and A7S III.

Clearly, both of the cameras enjoy the same exact MP albeit different sensor measurements. The P300 has the smaller sensor which is going to make achieving shallower DOF more difficult. The older P300 will be disadvantaged with regard to sensor innovation.
