This detailed comparison helps you understand which camera is better suited for your needs, whether you're an enthusiast, a professional, or a casual photographer.
Sensor and Image Quality
Olympus OM-D E-M5 Mark III
The Olympus OM-D E-M5 Mark III is equipped with a Micro Four Thirds MFT sensor of 20 megapixels. This sensor provides good image quality with decent dynamic range and color accuracy. However, it has a lower performance in low light compared to full-frame sensors, which means you may need a bit more light for optimal results.
Sony A7 III
The Sony A7 III has a full-frame sensor with 24.2 megapixels. This larger sensor size offers superior image quality, especially in low-light conditions, due to its better dynamic range and higher ISO performance. The larger sensor size also allows for greater depth of field flexibility and clearer details in low light.
Autofocus
Olympus OM-D E-M5 Mark III
The E-M5 Mark III boasts a 121-point contrast-detection autofocus system. While this system is excellent for most shooting scenarios, it may not be as responsive as phase-detection systems when dealing with fast-moving subjects, making it a bit slower in those situations.
Sony A7 III
The A7 III features a 693-point phase-detection and 425-point contrast-detection autofocus system. This advanced system is particularly efficient for tracking moving subjects, making it an ideal choice for action and wildlife photography. The superior autofocus performance enhances the overall shooting experience and captures the moment without delay.
Body and Design
Olympus OM-D E-M5 Mark III
The E-M5 Mark III is a compact and lightweight camera, weighing around 500g. Its weather-sealed body makes it suitable for outdoor photography, and it benefits from in-body image stabilization (IBIS), which helps to compensate for camera shake effectively.
Sony A7 III
In comparison, the A7 III is larger and heavier at around 650g. It is also weather-sealed but not as compact as the Olympus model. Additionally, the A7 III also has built-in image stabilization, but its effectiveness can depend on the lens used, meaning some lenses might not offer the optimal stabilization benefits.
