10 Best Four Thirds Camera 2025 in the United States

The OM SYSTEM Olympus OM-1 Mark II is a strong contender in the four-thirds camera category, particularly for outdoor photography enthusiasts and wildlife photographers. It features a 20.4 MP stacked BSI Live MOS sensor, which delivers impressive image quality in various lighting conditions. The included M.Zuiko Digital ED 12-40mm f/2.8 PRO II lens is versatile, allowing for both wide-angle and zoom shots, making it suitable for landscapes and close-ups alike.

One of the standout strengths of this camera is its weather-sealed design, providing reliability in unpredictable outdoor conditions. The battery life is commendable too, lasting around 520 minutes, which is beneficial for long shooting sessions. With features like continuous autofocus and a fast frame rate of 60 FPS, capturing fast-moving subjects is easier and more precise.

There are some drawbacks to consider. The autofocus system relies on contrast detection, which can be slower compared to phase detection systems found in some competitors. While the camera does offer digital image stabilization, it may not be as effective as mechanical stabilization systems, especially in very dynamic situations. The video capabilities are good, but not as advanced as some higher-end models, which may leave video creators wanting more. Additionally, while the build quality is solid, the camera is slightly heavier compared to other options in the market, which can be a concern for users looking for portability.

The OM SYSTEM OLYMPUS E-M10 Mark IV is a solid choice for anyone looking to enter the world of four-thirds cameras, especially for amateur photographers. Its 20 MP Live MOS sensor delivers decent image quality, and the in-body 5-axis image stabilization helps capture sharp images, even in challenging conditions. This camera is particularly user-friendly, boasting a flip-down monitor that makes it ideal for selfies, along with 16 art filters to enhance creativity.

One of its notable strengths is its 4K video capabilities, appealing to those interested in videography. Plus, its connectivity features, including Wi-Fi and Bluetooth, make sharing images quick and easy. The camera is compact and lightweight, making it convenient for travel and everyday use. However, users should consider the limitations in battery life, as it may not last for extensive shooting sessions. Additionally, it lacks weather sealing, which might be a drawback for outdoor photography in unpredictable conditions.

The autofocus system is relatively efficient with 121 points, but it primarily uses contrast detection, which can be slower compared to phase detection systems found in some higher-end models. While the lens compatibility is broad due to the Micro Four Thirds mount, some users may find themselves wanting additional lenses for varied photography styles. The E-M10 Mark IV offers a great balance of features for beginners and casual photographers, making it a worthy contender in the four-thirds category.

The Panasonic LUMIX GH7 is a top-tier mirrorless camera designed for professionals who prioritize video production without compromising on still photography. Its 25.2 MP BSI CMOS sensor offers excellent image quality and enables high dynamic range shooting, which is ideal for capturing vibrant and detailed photos and videos in various lighting conditions. The camera supports 5.7K video recording with advanced formats like Apple ProRes RAW, making it particularly appealing to videographers. Additionally, its robust autofocus system with 315 points ensures quick and accurate focusing, which is crucial for capturing fast-moving subjects.

One of the standout features is the 32-bit float recording that simplifies audio management during shoots, allowing for a more streamlined workflow. The camera's weather-sealed body enhances durability, making it suitable for outdoor shoots as well. With a continuous shooting speed of 14 fps and a tilting touchscreen for easy framing, the GH7 caters well to both photography and videography needs.

The GH7 isn't without its drawbacks. Its relatively high learning curve may be challenging for beginners, as it demands some technical knowledge to fully utilize its capabilities. Battery life, while decent, might not last through extended shooting sessions, especially in video mode. Additionally, while it supports a wide array of lenses due to its Micro Four Thirds mount, the cost of quality lenses can add up. Lastly, the camera's weight of 1.8 pounds may be cumbersome for those looking for a lightweight option.

The Panasonic LUMIX GH7 is an excellent choice for professional content creators and enthusiasts who seek advanced video capabilities alongside strong photographic performance, provided they are prepared for its complexity and weight.
