Nikon D5500 vs Pentax K-3 Overview and Optics

The Pentax K-3 outperforms the Nikon D5500 in optics with a score of 74/100 compared to the D5500’s 65/100. Both cameras share some common specifications, such as having a 24-megapixel CMOS sensor, an APS-C sensor size, and their respective brand’s lens mounts – the Nikon F DX for the D5500 and the Pentax KAF for the K-3.

The Pentax K-3 excels by offering a higher shooting speed of 8.3 frames per second, compared to the Nikon D5500’s 5 frames per second. This makes the K-3 more suitable for capturing fast-moving subjects. Additionally, the K-3 has image stabilization built into the camera body, which aids in reducing camera shake and improving image sharpness.

On the other hand, the Nikon D5500 boasts a slightly better DXOMARK score for its sensor at 84, compared to the Pentax K-3’s score of 80. This means that the D5500’s sensor has a marginally higher potential for image quality. Furthermore, the D5500 contains an Expeed 4 processor, while the K-3 uses a Prime III processor. However, the difference in processors does not significantly impact the optics comparison.

The Pentax K-3’s higher shooting speed and built-in image stabilization make it the superior choice in terms of optics. While the Nikon D5500 has a slightly higher DXOMARK sensor score, it does not outweigh the advantages offered by the K-3. Therefore, the Pentax K-3 is the better option for those prioritizing optical performance in their camera choice.

Nikon D5500 vs Pentax K-3 Features and Benefits

The Nikon D5500 and Pentax K-3 both have a feature score of 59 out of 100. Despite having the same score, there are differences in their features that set them apart.

Both cameras have a 3.2-inch screen size and a screen resolution of 1,037,000 dots, providing clear and crisp image previews. However, the Nikon D5500 has a touchscreen, whereas the Pentax K-3 does not. This allows for easier navigation and control on the D5500. Additionally, the D5500 has a flip screen, which the K-3 lacks. This feature is useful for capturing images from various angles and positions.

The Nikon D5500 stands out with its built-in WIFI, allowing for easy sharing and transferring of images. The Pentax K-3 does not have this feature, making it less convenient for users who want to share their photos quickly. However, neither camera has GPS or Bluetooth capabilities.

Despite the lack of additional features, the Pentax K-3 still holds its ground as a solid camera choice. It is important to note that a camera’s overall quality is not solely determined by its feature score, but rather by the combination of its specifications and performance.

When comparing the Nikon D5500 and Pentax K-3 based on their features, the D5500 has a slight advantage with its touchscreen and flip screen, as well as built-in WIFI. However, the K-3 remains a viable option for users who prioritize other aspects of a camera’s performance over its features. Ultimately, the choice between these two cameras will depend on the user’s preferences and needs.
