Fujifilm X-T4 vs Pentax K-3 Mark III Overview and Optics

The Pentax K-3 Mark III outperforms the Fujifilm X-T4 in optics, scoring 82/100 compared to the X-T4’s 73/100. Both cameras share several specifications, such as 26-megapixel CMOS sensors, APS-C sensor sizes, and image stabilization. They also have distinct lens mounts, with the X-T4 using Fujifilm X and the K-3 Mark III using Pentax KAF2.

The K-3 Mark III excels with its DXOMARK sensor score of 96, which the X-T4 lacks as DXOMARK does not score Fujifilm cameras. This high score signifies better sensor performance in the K-3 Mark III. Additionally, the K-3 Mark III uses the Prime IV processor, which contributes to its superior optics score.

Conversely, the X-T4 has a faster shooting speed of 20 compared to the K-3 Mark III’s 12. This advantage allows the X-T4 to capture more frames per second, making it better suited for action and sports photography.

Considering these points, the Pentax K-3 Mark III offers better optics due to its high DXOMARK sensor score and Prime IV processor. However, the Fujifilm X-T4 provides a faster shooting speed, which may be more appealing to photographers who prioritize capturing fast-moving subjects. Ultimately, the choice between these cameras depends on individual preferences and specific photography needs, but the K-3 Mark III has a clear edge in optics performance.

Fujifilm X-T4 vs Pentax K-3 Mark III Video Performance

The Fujifilm X-T4 outperforms the Pentax K-3 Mark III in video capabilities, scoring 91 points compared to the latter’s 83 points. Both cameras share some common features, such as 4K video resolution and built-in time-lapse functionality. However, the X-T4 boasts superior specs, which contribute to its higher score and better performance in video recording.

The Fujifilm X-T4 offers a higher maximum video dimension of 4096 x 2160, compared to the Pentax K-3 Mark III’s 3840 x 2160. This difference in dimensions allows the X-T4 to produce videos with greater detail and clarity. Additionally, the X-T4 has a higher maximum video frame rate of 120fps, doubling the K-3 Mark III’s 60fps. This higher frame rate enables the X-T4 to capture smoother slow-motion footage and produce more fluid videos.

Despite its lower score, the Pentax K-3 Mark III still performs well in video recording. It shares the 4K video resolution and built-in time-lapse functionality with the X-T4, making it a capable camera for various video projects. However, its lower video dimensions and frame rate limit its potential compared to the X-T4.

Based on these points, the Fujifilm X-T4 is the better camera for video recording, offering higher video dimensions and a faster frame rate for improved video quality and smoothness. The Pentax K-3 Mark III, while still a competent camera, falls short in these areas. Filmmakers and content creators should consider these differences when choosing between the two cameras for their video projects.
