Nikon D4 Vs D4s: Precision Autofocus For Capturing Every Detail

The Nikon D4 and D4S are two flagship DSLRs released by Nikon in 2012 and 2014, respectively. Both cameras are renowned for their exceptional image quality, rugged build, and advanced autofocus systems. In this detailed comparison, we will delve into the intricacies of the nikon d4 vs d4s autofocus and explore the key differences that set these two cameras apart.

Autofocus System Overview

The Nikon D4 and D4S feature advanced autofocus (AF) systems that employ a combination of phase detection and contrast detection sensors. The D4 boasts a 51-point AF system, while the D4S boasts a more advanced 51-point AF system with 15 cross-type sensors.

Phase Detection Points

Phase detection autofocus (PDAF) is a faster and more accurate method of focusing compared to contrast detection. The D4 has 51 phase detection points, while the D4S has 51 phase detection points with 15 cross-type sensors. Cross-type sensors are more sensitive to both horizontal and vertical lines, providing greater accuracy in low-light conditions.

Coverage and Sensitivity

The D4’s AF system covers a wider area of the frame, with 51 AF points spread across the entire frame. The D4S’s AF system, on the other hand, has 51 AF points concentrated in the central area of the frame, providing greater density and accuracy for subjects in the center. Both cameras have a maximum AF sensitivity of -2 EV, allowing them to focus in extremely low-light conditions.

Tracking Performance

The D4S has a more advanced tracking algorithm compared to the D4, which results in improved subject tracking capabilities. The D4S can track moving subjects more effectively, even in low-light conditions or when the subject is partially obscured.

Dynamic AF Area Modes

Both the D4 and D4S offer a variety of dynamic AF area modes, including Single-point AF, Dynamic-area AF, and 3D-tracking AF. These modes allow photographers to customize the AF system to suit different shooting scenarios.

Shutter Speed and AF

The D4S has a faster maximum shutter speed of 1/8000s compared to the D4’s 1/4000s. This higher shutter speed allows the D4S to capture sharper images of moving subjects, even when using a wide aperture.

Lens Compatibility

Both the D4 and D4S are compatible with Nikon’s F-mount lenses. However, the D4S supports a wider range of lenses, including the latest AF-S NIKKOR lenses with built-in vibration reduction (VR).

Other Autofocus Features

In addition to the key differences mentioned above, the D4 and D4S offer a range of other autofocus features, including:

• Autofocus fine-tuning: Allows photographers to adjust the AF system to different lenses.
• Focus limit: Restricts the AF system to a specific range of distances.
• AF-ON button: Provides dedicated control over autofocus activation.

Key Points: Choosing the Right Camera for Your Needs

Both the Nikon D4 and D4S are exceptional cameras with advanced autofocus systems. While the D4 offers a wider AF coverage, the D4S boasts a more advanced AF system with increased accuracy, tracking performance, and lens compatibility. Ultimately, the best choice between the two depends on the specific needs and preferences of the photographer.
