Olympus SZ-10 vs Sony A7 III

Let's look a little more in depth at the Olympus SZ-10 and Sony A7 III, one is a Small Sensor Superzoom and the other is a Pro Mirrorless by rivals Olympus and Sony. There exists a huge gap among the sensor resolutions of the SZ-10 (14MP) and A7 III (24MP) and the SZ-10 (1/2.3") and A7 III (Full frame) boast totally different sensor sizing.

The SZ-10 was released 8 years prior to the A7 III which is a fairly significant gap as far as camera technology is concerned. Both of these cameras have different body design with the Olympus SZ-10 being a Compact camera and the Sony A7 III being a SLR-style mirrorless camera.

Before we go into a more detailed comparison, here is a simple synopsis of how the SZ-10 grades vs the A7 III with respect to portability, imaging, features and an overall mark.

Following is a sample of the gallery pics for Olympus SZ-10 and Sony Alpha A7 III. The complete galleries are available at Olympus SZ-10 Gallery and Sony A7 III Gallery.

When you are going to travel with your camera often, you will have to factor its weight and measurements. The Olympus SZ-10 has outer measurements of 106mm x 67mm x 38mm (4.2" x 2.6" x 1.5") with a weight of 215 grams (0.47 lbs) whilst the Sony A7 III has proportions of 127mm x 96mm x 74mm (5.0" x 3.8" x 2.9") with a weight of 650 grams (1.43 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will change depending on the lens you choose during that time. Here is a front view scale comparison of the SZ-10 compared to the A7 III.

Considering dimensions and weight, the portability grade of the SZ-10 and A7 III is 90 and 63 respectively.

Normally, its difficult to visualise the contrast in sensor dimensions only by viewing specs. The image here should give you a more clear sense of the sensor sizing in the SZ-10 and A7 III.

As you can plainly see, the two cameras have different megapixel count and different sensor dimensions. The SZ-10 featuring a smaller sensor will make getting shallower DOF harder and the Sony A7 III will provide you with more detail as a result of its extra 10MP. Greater resolution can also help you crop photos a bit more aggressively. The more aged SZ-10 will be disadvantaged in sensor innovation.
