Taking into account the higher score, lower price, and similar features, the Pentax K-S2 stands out as the better option. However, for those prioritizing portability, the Nikon D5500 may be a more suitable choice.

Nikon D5500 vs Pentax K-S2 Overview and Optics

The Pentax K-S2 outperforms the Nikon D5500 in optics with a score of 70/100, as opposed to the Nikon’s 65/100. Both cameras share common specifications, including a CMOS sensor, APS-C sensor size, and similar shooting speeds (5 for the Nikon D5500 and 5.4 for the Pentax K-S2). Additionally, both cameras have proprietary processors: the Nikon D5500 uses the Expeed 4, while the Pentax K-S2 employs the Prime MII.

The Pentax K-S2 surpasses the Nikon D5500 in several aspects. The K-S2 boasts a higher DXOMARK score for its sensor, 88, compared to the D5500’s 84. This difference reflects the K-S2’s superior image quality. Furthermore, the Pentax K-S2 has image stabilization, while the Nikon D5500 lacks this feature. Image stabilization allows for sharper images, especially in low-light conditions or when using longer lenses.

However, the Nikon D5500 has its advantages as well. It possesses a higher megapixel count, 24.2, compared to the Pentax K-S2’s 20. This difference means the Nikon D5500 can capture more detailed images. Additionally, the Nikon D5500 utilizes the Nikon F DX lens mount, which offers a wider range of compatible lenses than the Pentax KAF2 mount found on the K-S2.

Taking these factors into account, the Pentax K-S2 proves to be the better choice in terms of optics due to its higher sensor score and image stabilization. However, the Nikon D5500 may be more suitable for those who prioritize higher megapixels and a broader lens selection. Ultimately, each camera has its strengths and weaknesses, and the decision should be based on individual preferences and requirements.
