The Pentax K-S2 outperforms the Pentax K-S1 with a score of 66/100 compared to the K-S1’s 57/100. Both cameras share the DSLR camera type and were released within a year of each other, with the K-S1 in 2014 and the K-S2 in 2015. The K-S2 is superior due to its higher score, which reflects its better features and performance. However, the K-S1 has its advantages, such as being lighter at 558g compared to the K-S2’s 678g, and more affordable with a launch price of $749 versus the K-S2’s $800. Despite these benefits, the K-S2 remains the more desirable option due to its overall higher score and performance.

Pentax K-S1 vs K-S2 Overview and Optics

The Pentax K-S2 emerges as the winner in the optics comparison with a score of 70/100, slightly ahead of the Pentax K-S1 which scored 68/100. Both cameras share several specifications, including a 20-megapixel resolution, 5.4 shooting speed, CMOS sensor type, Prime MII processor, APS-C sensor size, and image stabilization. They also both use a Pentax KAF lens mount, with the K-S2 having an upgraded KAF2 mount.

The K-S2 outperforms the K-S1 in terms of its DXOMARK sensor score, boasting an impressive 88 points compared to the K-S1’s 78 points. This higher score indicates that the K-S2’s sensor provides better image quality and improved performance in low light conditions. The K-S2’s KAF2 lens mount also offers compatibility with a wider range of lenses, allowing for greater flexibility in shooting scenarios.

On the other hand, the K-S1 has a slightly higher megapixel count at 20.12 compared to the K-S2’s 20 megapixels. This marginal difference may result in marginally sharper images, but it is not significant enough to outweigh the advantages offered by the K-S2’s superior sensor and lens mount.

In comparing the optics of the Pentax K-S1 and K-S2, the K-S2 proves to be the better choice due to its higher DXOMARK sensor score and upgraded lens mount. The K-S1’s marginally higher megapixel count does not provide a significant advantage over the K-S2. Therefore, photographers seeking better image quality and greater lens compatibility should opt for the Pentax K-S2.

Pentax K-S1 vs K-S2 Video Performance

The Pentax K-S2 outperforms the Pentax K-S1 in video capabilities, scoring 70/100 compared to the K-S1’s 43/100. Both cameras share some common specifications, such as Full HD video resolution and maximum video dimensions of 1920 x 1080. However, there are significant differences between the two models that contribute to the K-S2’s higher score.

The K-S2 has a higher maximum video frame rate of 60fps, while the K-S1 is limited to 30fps. This means the K-S2 can capture smoother and more detailed video, especially in fast-paced situations. Additionally, the K-S2 has built-in time-lapse functionality, allowing users to create stunning time-lapse videos without the need for additional equipment or software. These features make the K-S2 a more versatile and powerful tool for videographers.

On the other hand, the K-S1 does not offer any significant advantages in video capabilities over the K-S2. It has a lower video score and lacks features found in the K-S2, such as the higher frame rate and built-in time-lapse functionality. Therefore, it falls short in comparison to its counterpart.

Considering the differences in video capabilities, it is clear that the Pentax K-S2 is the superior choice for those seeking a camera with strong video performance. Its higher frame rate and time-lapse functionality make it a more capable and versatile tool for capturing high-quality video. The Pentax K-S1, while still offering Full HD resolution, does not provide the same level of performance and features as the K-S2, making it a less desirable option for videographers.

Pentax K-S1 vs K-S2 Features and Benefits

The Pentax K-S2 outperforms the Pentax K-S1 in terms of features, scoring 68/100 compared to the K-S1’s 41/100. Both cameras share some common specifications, including a 3-inch screen size and a screen resolution of 921,000 dots. Neither camera has a touchscreen.

The K-S2’s higher score comes from its additional features, which make it a more versatile and user-friendly camera. It has a flip screen, allowing for easier composition and shooting from various angles. The K-S2 also includes GPS, which is useful for geotagging photos and tracking locations during shoots. Furthermore, the K-S2 offers Wi-Fi and Bluetooth connectivity, enabling wireless file transfers and remote camera control through a compatible smartphone or tablet.

On the other hand, the K-S1 lacks these advanced features, making it a simpler and more basic camera in comparison. However, this simplicity may appeal to some users who prefer a more straightforward, no-frills shooting experience.

Comparing the two cameras’ features, the Pentax K-S2 is the clear winner, offering greater flexibility and convenience for photographers with its flip screen, GPS, Wi-Fi, and Bluetooth capabilities.
