OM SYSTEM Olympus OM-1 Mark II Micro Four Thirds vs Sony ILCE7SM3/B Alpha 7S III FullFrame ILC Camera

Introduction to the Cameras

The OM SYSTEM Olympus OM-1 Mark II and the Sony ILCE7SM3/B Alpha 7S III are two exceptional mirrorless cameras, each catering to different photography needs. The Olympus OM-1 Mark II is priced at $1,999.99, making it about 46% cheaper than the Sony Alpha 7S III, which retails for $3,698.00. While both cameras offer impressive features, their distinct characteristics and target audiences set them apart.

Sensor and Image Quality

The OM SYSTEM Olympus OM-1 Mark II boasts a 20MP BSI Stacked sensor, designed for high-resolution images with low noise, ideal for outdoor photography. In contrast, the Sony Alpha 7S III features a 12.1MP Exmor R sensor optimized for 4K video, which excels in low-light conditions with an ISO sensitivity reaching up to 409,600. While the Olympus offers higher resolution for still images, the Sony prioritizes video performance and superior low-light capabilities, appealing to videographers and those shooting in challenging lighting situations.

Autofocus Capabilities

The autofocus systems of both cameras are impressive but cater to different preferences. The OM SYSTEM Olympus OM-1 Mark II incorporates Cross Quad Pixel AF technology with 1,053 focus points, ensuring precise focusing across a wide area. On the other hand, the Sony Alpha 7S III features a fast hybrid autofocus system with 759 phase detection points, allowing for quick and accurate focus, especially during video capture. Depending on whether you prioritize still photography or video performance, each camera offers unique autofocus strengths.

Processing Power

Processing speed is another critical factor where these cameras diverge. The Olympus OM-1 Mark II is powered by the TruePic X engine, which delivers up to three times faster processing compared to its predecessors. Conversely, the Sony Alpha 7S III utilizes a new BIONZ XR processing engine that provides eight times more processing power than prior models. This significant difference enables the Sony to handle higher resolutions and frame rates, particularly beneficial for videographers aiming for high-quality 4K video at 120p.

Durability and Design

In terms of build quality, the OM SYSTEM Olympus OM-1 Mark II is designed with an IP53 rating, making it dustproof, splashproof, and able to withstand temperatures as low as -10°C. This weather-sealed design makes it an excellent choice for outdoor photographers who often face unpredictable conditions. The Sony Alpha 7S III, while also robust, does not specifically highlight weather resistance in its specifications, potentially making it less suitable for extreme conditions. For photographers who prioritize durability in their gear, the Olympus has a clear advantage.

Video Features

Video capabilities are a strong suit for the Sony Alpha 7S III. It supports up to 4K 120p recording in 10-bit 4:2:2 with full pixel readout across all recording modes, appealing to filmmakers seeking high-quality footage. The OM SYSTEM Olympus OM-1 Mark II, while capable of video recording, is primarily geared towards still photography and computational photography functions, such as Handheld High Res Shot and Focus Stacking. If your primary focus is on creating cinematic video content, the Sony's advanced video features may be the deciding factor.

Pricing and Value

The price difference between these two cameras is substantial, with the OM SYSTEM Olympus OM-1 Mark II priced at $1,999.99 and the Sony Alpha 7S III at $3,698.00. This means that the Olympus is approximately $1,698 cheaper, making it a more budget-friendly option for those who still want high-quality photography without breaking the bank. However, the higher price of the Sony can be justified by its advanced video capabilities and superior low-light performance, appealing to professionals and serious enthusiasts.

User Experience and Target Audience

Both cameras cater to different types of users. The OM SYSTEM Olympus OM-1 Mark II is ideal for nature photographers and outdoor enthusiasts who require a durable camera with high-resolution capabilities. Meanwhile, the Sony Alpha 7S III is tailored for videographers and content creators who need exceptional low-light performance and advanced video features. The distinct sales ranks of both cameras—28,860 for the Olympus and 30,385 for the Sony—suggest that both have found their respective audiences, but the Olympus may appeal more to those prioritizing still photography over video.

Which should you buy?

Choosing between the OM SYSTEM Olympus OM-1 Mark II and the Sony ILCE7SM3/B Alpha 7S III depends largely on your photography needs. If you are focused on outdoor photography, durability, and high-resolution images, the Olympus OM-1 Mark II is the superior choice, especially at its lower price point of $1,999.99. However, if your work revolves around high-quality video production and low-light performance, the Sony Alpha 7S III, despite its higher price of $3,698.00, offers features that cater specifically to those requirements. Overall, understanding your primary use case will guide you to the right choice.
