The Pentax K-3 Mark III and Nikon D500 are two highly acclaimed cameras renowned for their exceptional performance in nature and wildlife photography. Both cameras offer a compelling set of features, but each has its unique strengths and weaknesses. This comprehensive comparison will delve into the key differences between the Pentax K-3 Mark III and Nikon D500, helping you make an informed decision about which camera is the best choice for your specific needs.
Sensor and Image Quality
The Pentax K-3 Mark III features a 25.7-megapixel APS-C CMOS sensor, while the Nikon D500 sports a 20.9-megapixel DX-format CMOS sensor. Both cameras deliver excellent image quality, but the Pentax K-3 Mark III has a slight edge in resolution and dynamic range. However, the Nikon D500’s larger pixels provide better low-light performance and less noise at higher ISOs.
Autofocus System
The Pentax K-3 Mark III boasts a hybrid autofocus system with 101 phase-detection and 273 contrast-detection AF points. The Nikon D500, on the other hand, features a 153-point AF system with 99 cross-type sensors.
