  The D7500 foregoes an anti-aliasing (AA) filter, enhancing sharpness at the risk of moiré in fine patterns. The D800 retains its AA filter, slightly reducing crispness but preventing moiré artifacts in high-resolution output.

Autofocus Systems: Speed, Accuracy, and Tracking

Critical for fast action, wildlife, and sports shooting is the autofocus system. Both cameras utilize a 51-point AF system with 15 cross-type sensors, but their implementations differ.

• D7500 Autofocus Features
  The D7500’s true strength lies in faster, more intelligent AF thanks to the Expeed 5 processor and improved algorithms. It supports face detection in live view and touches AF, delivering excellent accuracy with moving subjects. Continuous AF reaches 8 fps burst shooting, enabling better tracking of erratic movements seen in sports and wildlife.

• D800 Autofocus Characteristics
  Despite having the same number of AF points, the D800’s older Expeed 3 engine means slower computation and 4 fps continuous shooting. Autofocus is reliable but can feel less responsive in fast-paced scenarios. Face detection is present but no touchscreen or phase detection in live view limits live subject tracking capabilities.

In practical use, I found the D7500 more adept at maintaining focus on fast-moving wildlife and athletes, with snappier focus acquisition and tracking consistency. The D800 excels in precision focusing for static subjects like landscapes and portraits but is challenged by rapid autofocus demands.
