Both cameras have similar dimensions, with the K-50 at 130 x 97 x 71mm and the K-S1 at 121 x 93 x 70mm.

The K-50 stands out with its slightly larger size and heavier weight, measuring 650g (1.43lbs), while the K-S1 is lighter at 558g (1.23lbs). Although the K-S1 is more expensive and compact, its lighter weight makes it more comfortable to carry and handle.

Despite their similar scores, the K-50’s lower price makes it a more attractive option for budget-conscious photographers. The K-S1, on the other hand, offers a lighter and more compact design for those who prioritize portability. Ultimately, the choice between these two cameras comes down to individual preferences and priorities.

Pentax K-50 vs K-S1 Overview and Optics

The Pentax K-S1 outperforms the Pentax K-50 in optics with a score of 68/100 compared to the K-50’s 62/100. Both cameras share several common specifications, including the CMOS sensor type, APS-C sensor size, Pentax KAF lens mount, and image stabilization. These shared features provide a solid foundation for both cameras’ optical performance.

The K-S1 has a higher megapixel count of 20.12, compared to the K-50’s 16.28. This difference allows the K-S1 to capture more detailed images, giving it an advantage in terms of image quality. Furthermore, the K-S1’s Prime MII processor is an upgrade from the K-50’s Prime M processor, which contributes to the K-S1’s superior image processing capabilities.

On the other hand, the K-50 has a faster shooting speed of 6 frames per second (fps) compared to the K-S1’s 5.4 fps. This advantage in shooting speed may benefit users who need to capture fast-moving subjects or action scenes. However, it’s worth noting that the K-S1 has a slightly better DXOMARK sensor score of 79, compared to the K-S1’s 78, indicating that the K-50’s sensor performs well despite its lower megapixel count.

In terms of optics, the Pentax K-S1 stands out due to its higher megapixel count and upgraded processor, leading to better image quality and processing capabilities. The K-50, while not as strong in these areas, offers a faster shooting speed that may appeal to some users. Ultimately, the choice between the two cameras will depend on individual preferences and priorities, with the K-S1 being the better option for those prioritizing image quality and the K-50 catering to those in need of faster shooting capabilities.

Pentax K-50 vs K-S1 Video Performance

The Pentax K-50 emerges as the winner in the video capabilities comparison, scoring 57/100, while the Pentax K-S1 scores 43/100. Both cameras share some common specifications, such as Full HD max video resolution and 1920 x 1080 max video dimensions. Additionally, they both offer a max video frame rate of 30fps.

The K-50 outperforms the K-S1 primarily due to its built-in time-lapse functionality. This feature allows users to capture a series of images at set intervals and combine them to create a time-lapse video, showcasing the passage of time in a visually appealing manner. The K-S1 lacks this feature, which contributes to the 14-point difference in their video scores.

On the other hand, the K-S1 does not have any specific advantages over the K-50 in terms of video capabilities. Both cameras share the same basic video specifications, and the lack of time-lapse functionality in the K-S1 places it at a disadvantage compared to the K-50.

Considering the video capabilities of both cameras, the Pentax K-50 holds a clear advantage over the K-S1, thanks to its time-lapse functionality. This feature allows users to explore creative possibilities and capture dynamic scenes, making the K-50 a more versatile option for videography. The Pentax K-S1, while offering similar basic video specifications, falls short due to its lack of time-lapse functionality, limiting its appeal for those looking for advanced video features.

Pentax K-50 vs K-S1 Features and Benefits

The Pentax K-50 emerges as the winner in this comparison, scoring 54 out of 100 in features, while the Pentax K-S1 scores 41 out of 100. Both cameras share several specifications, such as a 3-inch screen size, a screen resolution of 921,000 dots, and the absence of a touchscreen, flip screen, GPS, WIFI, and Bluetooth.

The Pentax K-50’s higher score reflects its better features. While both cameras lack a touchscreen and flip screen, the K-50 offers more in other areas. However, it is essential to examine the specific features that contribute to the higher score to understand the camera’s advantages better.

On the other hand, the Pentax K-S1’s lower score may indicate fewer features or less advanced capabilities. Despite this, there might be aspects where the K-S1 outperforms the K-50. A thorough comparison of the two cameras is necessary to determine any advantages the K-S1 may have over the K-50.

After examining the shared specifications and the advantages of the winning camera, it is clear that the Pentax K-50 is the superior option. Its higher score confirms its better features and capabilities compared to the Pentax K-S1. However, potential buyers should also consider any unique advantages the K-S1 may have over the K-50 before making a decision.

In the end, the Pentax K-50 stands out as the better camera due to its higher feature score. While both cameras share several specifications, the K-50’s superior performance makes it a more attractive choice for photographers seeking a reliable and versatile camera.

Pentax K-50 vs K-S1 Storage and Battery

In the storage and battery category, both the Pentax K-50 and the Pentax K-S1 have identical scores of 24/100. These cameras share common specifications, including one memory card slot and compatibility with SD, SDHC, and SDXC memory cards. Their battery life is the same, providing 410 shots per charge, and both use the D-LI109 battery type. Neither camera offers USB charging.
