The Pentax K-3 Mark III outperforms the Pentax K-1 Mark II with a score of 83/100 compared to 80/100. Both cameras are DSLRs and were launched at the same price of $1,999. They share similarities in their announcement dates, with the K-3 Mark III being released in 2021 and the K-1 Mark II in 2018.

The K-3 Mark III has the advantage of being smaller and lighter, measuring 135 x 104 x 74mm and weighing 820g, making it more portable than the K-1 Mark II, which measures 137 x 110 x 86mm and weighs 1010g. This difference in size and weight can be crucial for photographers who value mobility and ease of handling.

On the other hand, the K-1 Mark II might still appeal to some users due to its slightly lower score, which does not necessarily imply a significant difference in performance. Both cameras share a range of features and capabilities, and the choice between them might come down to individual preferences and specific needs.

Taking these factors into account, the K-3 Mark III stands out as the better camera, primarily due to its smaller size and lighter weight. However, the K-1 Mark II remains a viable option for those who don’t prioritize portability as much.

Pentax K-3 Mark III vs K-1 Mark II Overview and Optics

The Pentax K-1 Mark II comes out on top in the optics comparison with a score of 85/100, a 3-point lead over the Pentax K-3 Mark III’s score of 82/100. Both cameras share some common specifications, such as the CMOS sensor type, Prime IV processor, DXOMARK sensor score of 96, and image stabilization. Additionally, both cameras use the Pentax K lens mount system, with the K-3 Mark III using the KAF2 mount and the K-1 Mark II using the KAF4 mount.

The K-1 Mark II’s advantage lies in its higher megapixel count of 36 compared to the K-3 Mark III’s 26 megapixels. This results in higher resolution images, providing more detail and better image quality. Furthermore, the K-1 Mark II has a full-frame sensor, which offers better low-light performance and a wider dynamic range than the K-3 Mark III’s APS-C sensor.

On the other hand, the K-3 Mark III has a faster shooting speed of 12 frames per second, compared to the K-1 Mark II’s 4.4 frames per second. This makes the K-3 Mark III more suitable for capturing fast-moving subjects and action photography.

Considering these points, the Pentax K-1 Mark II is the better choice for photographers who prioritize image quality, resolution, and low-light capabilities. Meanwhile, the Pentax K-3 Mark III is a more suitable option for those who require a faster shooting speed for action photography. Both cameras offer excellent optics, but the K-1 Mark II’s higher score reflects its superiority in key areas that contribute to overall image quality.
