Fujifilm X-T3 vs Sony a7 IV Overview and Optics
The Sony a7 IV outperforms the Fujifilm X-T3 in optics, scoring 85/100 compared to the X-T3’s 67/100. Both cameras share common specifications, including a CMOS sensor, but the Sony a7 IV surpasses the Fujifilm X-T3 in several aspects.
The Sony a7 IV has a higher megapixel count at 33, compared to the X-T3’s 26, allowing for greater image resolution. Additionally, the a7 IV boasts a full-frame sensor, which is larger than the X-T3’s APS-C sensor, resulting in better low-light performance and dynamic range. The Sony a7 IV also has a higher DXOMARK sensor score of 97, while the Fujifilm X-T3 does not have a DXOMARK score. Furthermore, the a7 IV features image stabilisation, which the X-T3 lacks, making it easier to capture sharp images in various shooting conditions.
However, the Fujifilm X-T3 has a faster shooting speed of 20 frames per second (fps) compared to the Sony a7 IV’s 10 fps. This advantage makes the X-T3 more suitable for capturing fast-moving subjects and action photography.
Considering these factors, the Sony a7 IV is the superior camera in terms of optics, offering higher resolution, a larger sensor, and image stabilisation. The Fujifilm X-T3, on the other hand, excels in shooting speed, making it a better choice for action photography. Ultimately, the decision between these two cameras comes down to the specific needs and preferences of the photographer.
