The Pentax K-3 Mark III outperforms the Nikon D500 with a score of 83/100 compared to the D500’s 75/100. Both cameras are DSLRs, announced in 2021 and 2016 respectively, and share a similar launch price of around $2000.

The Pentax K-3 Mark III is smaller and lighter, measuring 135 x 104 x 74mm and weighing 820g, while the Nikon D500 measures 147 x 115 x 81mm and weighs 860g. This makes the Pentax more portable and convenient for photographers on the go.

However, the Nikon D500 has its advantages as well. Being an older model, it has a longer track record and a more established user base, which can be helpful for support and community advice.

Considering the specifications, the Pentax K-3 Mark III is the clear winner due to its higher score, smaller size, and lighter weight. Nevertheless, the Nikon D500 remains a viable option for those who value the benefits of an established camera model.

Nikon D500 vs Pentax K-3 Mark III Overview and Optics

The Pentax K-3 Mark III outperforms the Nikon D500 in optics with a score of 82/100, compared to the Nikon D500’s score of 69/100. This 13-point difference is significant when comparing the cameras’ optical capabilities.

Both cameras share some common specifications, including a CMOS sensor, an APS-C sensor size, and compatibility with their respective lens mounts – Nikon F DX for the D500 and Pentax KAF2 for the K-3 Mark III. However, the similarities end there, with the Pentax K-3 Mark III offering superior features in other areas.

The Pentax K-3 Mark III has a higher megapixel count at 26, compared to the Nikon D500’s 20.9, allowing for more detailed and high-resolution images. Additionally, the K-3 Mark III boasts a faster shooting speed of 12 frames per second, as opposed to the D500’s 10 frames per second. The Pentax K-3 Mark III also has a higher DXOMARK score for its sensor at 96, compared to the Nikon D500’s score of 84, indicating better overall image quality.

The Nikon D500, on the other hand, features an Expeed 5 processor, which may provide faster processing and better noise reduction. However, this advantage is not enough to overcome the Pentax K-3 Mark III’s superior optical performance.

One notable feature that sets the Pentax K-3 Mark III apart is its built-in image stabilization, which the Nikon D500 lacks. This feature helps to reduce camera shake and produce sharper images, especially in low-light situations or when using slower shutter speeds.

Considering the significant differences in optical performance, the Pentax K-3 Mark III is the clear winner in this comparison. With its higher megapixels, faster shooting speed, better sensor score, and built-in image stabilization, the K-3 Mark III is a more capable camera for capturing high-quality images. While the Nikon D500 may have a slightly faster processor, it falls short in other critical areas, making the Pentax K-3 Mark III the better choice for photographers seeking superior optics.
