Pentax K-50 vs Ricoh GR III Overview and Optics

The Ricoh GR III outperforms the Pentax K-50 in optics with a score of 68/100 compared to the Pentax K-50’s 62/100. Both cameras share some common specifications, including an APS-C CMOS sensor, shooting speed, and image stabilization.

The Ricoh GR III excels with its 24-megapixel sensor, providing higher resolution images than the 16.28-megapixel Pentax K-50. Additionally, the GR III features a more advanced GR Engine 6 processor, which contributes to better image quality and processing. In contrast, the Pentax K-50 uses a Prime M processor. Despite having a lower DXOMARK score of 76 compared to the K-50’s 79, the Ricoh GR III still delivers superior overall optics performance.

On the other hand, the Pentax K-50 offers a faster shooting speed of 6 frames per second, compared to the Ricoh GR III’s 4 frames per second. This allows for capturing fast-moving subjects more effectively. Moreover, the K-50 has a Pentax KAF lens mount, enabling users to interchange lenses for various shooting scenarios. The Ricoh GR III, however, has a fixed lens mount, limiting its versatility.

Weighing the pros and cons, the Ricoh GR III is the winner in optics performance with its higher resolution, advanced processor, and overall score. This camera is ideal for users seeking superior image quality in a compact design. Meanwhile, the Pentax K-50 is better suited for those who prioritize shooting speed and lens versatility. Ultimately, the choice depends on the specific needs and preferences of the user.

Pentax K-50 vs Ricoh GR III Video Performance

The Ricoh GR III outperforms the Pentax K-50 in video capabilities, scoring 70/100 compared to the K-50’s 57/100. Both cameras share some common video specifications, such as Full HD maximum video resolution (1920 x 1080) and built-in time-lapse functionality. However, the Ricoh GR III surpasses the Pentax K-50 in a few key areas, making it the superior choice for videography.

The Ricoh GR III’s most significant advantage lies in its higher maximum video frame rate, offering 60fps compared to the Pentax K-50’s 30fps. This difference allows the GR III to capture smoother and more detailed video, particularly in fast-paced or action-packed scenes. Additionally, the higher frame rate provides more flexibility in post-production, such as creating slow-motion effects.

The Pentax K-50 does not have any distinct advantages over the Ricoh GR III in terms of video capabilities. Both cameras share the same maximum video resolution, dimensions, and time-lapse functionality. As a result, the K-50 cannot compete with the GR III’s higher frame rate, which is a critical factor for videographers.

Given the 13-point difference in video scores and the Ricoh GR III’s superior frame rate, it is evident that the GR III is the better choice for those prioritizing video capabilities. The Pentax K-50 may still be suitable for casual video users, but the Ricoh GR III offers a more advanced and versatile video experience.
