Design and Build Quality
The OM SYSTEM Olympus OM-3 features a vintage-styled, premium metal body that not only adds aesthetic value but also durability. With an IP53 rating, it is resistant to dust, splashes, and freezing temperatures, making it an ideal choice for outdoor photography.

Image Quality
When it comes to image quality, the LUMIX S9 shines with its 24.2MP full-frame sensor, which enables it to deliver stunning results, particularly in low-light conditions. This full-frame advantage allows for impressive photos and videos. Meanwhile, the OM-3's 20MP stacked BSI Live MOS sensor, though slightly lower in resolution, still offers excellent performance with computational photography features like High Res Shot and Focus Stacking. For photographers who require the best performance in challenging lighting, the LUMIX S9 may be the better option.
Features and Functionality
The OM SYSTEM Olympus OM-3 is equipped with advanced features such as a TruePic X Processor and a 2.36m-dot OLED electronic viewfinder that enhances the shooting experience. It also includes creative photography modes, such as Live Composite and Art Filters, appealing to artistic photographers. The LUMIX S9, on the other hand, excels in connectivity with ultra-fast Wi-Fi capabilities and seamless transfer of images to smartphones using the LUMIX Lab app. This feature is particularly useful for social media content creators looking to share their work quickly.
Stabilization and Autofocus
Image stabilization is crucial for achieving sharp images, and both cameras offer impressive solutions. The OM-3 features 5-axis image stabilization, which helps reduce blurriness caused by camera shake. Conversely, the LUMIX S9 implements new Active I.S. technology, enhancing stabilization further, especially during video recording. When it comes to autofocus, the LUMIX S9 uses Phase Hybrid AF, which provides fast and accurate focusing, ideal for capturing moving subjects. This may make the LUMIX S9 a preferred choice for action photographers.

At $1,699.99, the OM SYSTEM Olympus OM-3 is priced higher than the LUMIX S9, which is available for $1,497.99. This price difference of about $202 may influence a buyer's decision, especially considering the S9 also offers a full-frame sensor. However, the OM-3’s rugged features and creative capabilities might justify its higher price for certain users. Evaluating your budget alongside the features that matter most to you can guide your choice between these two cameras.
Which should you buy?
