The Olympus OM System OM-1 takes the lead with a score of 73/100, while the Panasonic Lumix DC-G9 trails behind with 70/100. Both cameras are mirrorless and share a few specifications, such as their launch prices of $2199 and $1699, respectively. The Olympus OM-1 is lighter at 599g (1.32lbs) and has a compact size of 135 x 92 x 73mm, making it more portable than the Panasonic G9, which weighs 658g (1.45lbs) and measures 137 x 97 x 92mm.

The Olympus OM-1’s advantage lies in its more recent release year of 2022, compared to the Panasonic G9’s 2017 release. This means the OM-1 likely benefits from newer technology and features. However, the Panasonic G9 has a lower launch price, making it a more budget-friendly option.

Taking these points into account, the Olympus OM System OM-1 stands out as the better option due to its lighter weight and newer technology. Meanwhile, the Panasonic Lumix DC-G9 could still be considered if budget is a priority.

Olympus OM System OM-1 vs Panasonic Lumix DC-G9 Overview and Optics

The Olympus OM System OM-1 emerges as the winner in the optics comparison with a score of 69/100, while the Panasonic Lumix DC-G9 scores 65/100. Both cameras share some specifications: they have 20 megapixels, Micro Four Thirds sensor size, Micro 4/3 lens mount, and image stabilisation.

The OM-1 outperforms the G9 in several aspects. The OM-1’s Stacked CMOS sensor type and TruePic X Dual Quad Core Processor contribute to its higher DXOMARK score of 85, compared to the G9’s DXOMARK score of 71. This difference indicates that the OM-1 captures superior image quality and detail. Additionally, the OM-1’s advanced processor provides faster image processing, which may result in better low-light performance and improved noise reduction.

On the other hand, the G9 has a higher shooting speed of 20 frames per second, compared to the OM-1’s 10 frames per second. This advantage allows the G9 to capture fast-moving subjects more effectively, making it a suitable choice for action and sports photography.

While the OM-1’s superior sensor and processor give it the edge in overall image quality, the G9’s faster shooting speed may appeal to photographers who prioritize capturing action-packed scenes. Both cameras offer excellent performance in their respective areas, and the choice between them ultimately depends on the specific needs and preferences of the photographer.
