Fujifilm X-T4 vs Olympus OM-D E-M1 Mark III Overview and Optics

The Fujifilm X-T4 outperforms the Olympus OM-D E-M1 Mark III in optics, scoring 73/100 compared to the Olympus’ 68/100. Both cameras share several specifications, including a CMOS sensor type, image stabilisation, and similar processors, the X-Processor 4 in the Fujifilm and the TruePic IX in the Olympus.

The X-T4 surpasses the E-M1 Mark III with its 26-megapixel sensor, APS-C sensor size, and Fujifilm X lens mount, allowing for higher resolution images and better overall image quality. The larger sensor size also contributes to improved low-light performance and dynamic range. Furthermore, the Fujifilm X lens mount offers a wide range of high-quality lenses compatible with the X-T4.

On the other hand, the Olympus OM-D E-M1 Mark III has a faster shooting speed at 60 frames per second compared to the Fujifilm’s 20 frames per second. This makes the Olympus more suitable for action photography or capturing fast-moving subjects. Additionally, the E-M1 Mark III has a DXOMARK score of 80 for its sensor, while the X-T4 does not have a DXOMARK score, as Fujifilm cameras are not scored by DXOMARK.

Despite the Olympus’ faster shooting speed and DXOMARK score, the Fujifilm X-T4’s higher megapixel count, larger sensor size, and superior lens mount make it the better option in terms of optics. The X-T4 is more suitable for photographers prioritising image quality and resolution, while the E-M1 Mark III may be preferable for those focusing on action photography or requiring faster shooting speeds.
