Fujifilm X-S10 vs Olympus OM-D E-M10 Mark IV Overview and Optics

The Fujifilm X-S10 outperforms the Olympus OM-D E-M10 Mark IV in optics, scoring 72/100 compared to the Olympus’ 63/100. Both cameras share common specifications, such as CMOS sensors, processors, image stabilization, and aspect ratios of 3:2 for the Fujifilm and 4:3 for the Olympus.

The Fujifilm X-S10 excels with its 26 megapixels, higher shooting speed of 20 frames per second, APS-C sensor size, and Fujifilm X lens mount. These features contribute to better image quality and performance, making the X-S10 the superior choice in this comparison.

On the other hand, the Olympus OM-D E-M10 Mark IV has a lower 20-megapixel count, slower shooting speed of 15 frames per second, smaller Micro Four Thirds sensor size, and a Micro 4/3 lens mount. However, it does have a DXOMARK score of 73 for its sensor, providing an objective measure of its quality, while the Fujifilm X-S10 does not have a DXOMARK score.

Despite the lower score, the Olympus OM-D E-M10 Mark IV still offers quality optics and features that may appeal to some users, particularly those who prefer a smaller, lighter camera with a more extensive range of compatible lenses due to its Micro 4/3 lens mount.

In this comparison, the Fujifilm X-S10 emerges as the better camera in terms of optics, with its higher megapixel count, faster shooting speed, and larger sensor size. However, the Olympus OM-D E-M10 Mark IV remains a viable option for those who prioritize a compact system with a wider lens selection.
