Nikon D4 Vs D4s Autofocus: Which One Captures The Action Faster?
What To Know
- Group-area AF allows you to select a group of focus points that will work together to track a moving subject, while 3D-tracking AF utilizes color information to maintain focus on a moving subject even if it momentarily leaves the selected focus point.
- If you frequently work in low-light conditions, require faster AF acquisition speed, or want more advanced AF features like Group-area AF and 3D-tracking AF, then the Nikon D4S is the clear winner.
- However, if you are on a tighter budget or do not need the additional features of the D4S, the Nikon D4 is still a capable camera with excellent AF performance.
The Nikon D4 and D4S are two professional-grade DSLRs that have been widely acclaimed for their exceptional autofocus (AF) capabilities. While both cameras share many similarities, there are a few key differences in their AF systems that may influence your choice between the two. In this comprehensive guide, we will delve into the intricacies of the Nikon D4 vs D4S autofocus, highlighting their strengths and weaknesses to help you make an informed decision.
Understanding Autofocus Systems in DSLR Cameras
Before we dive into the specifics of the Nikon D4 and D4S AF systems, let’s briefly discuss how autofocus works in DSLR cameras. Autofocus relies on sensors within the camera body or lens to detect contrast or phase differences between adjacent pixels in the image. This information is then used to adjust the focus of the lens until the subject appears sharp.
Nikon D4 vs D4S Autofocus: A Comparative Analysis
1. AF System Type:
- Nikon D4: Multi-CAM 3500FX 51-point AF system
- Nikon D4S: Multi-CAM 3500FX II 51-point AF system
The Nikon D4S features an updated version of the AF system found in the D4, known as the Multi-CAM 3500FX II. This improved AF system boasts a slightly faster acquisition speed and enhanced low-light performance.
2. AF Sensitivity:
- Nikon D4: -2 EV to +19 EV
- Nikon D4S: -4 EV to +19 EV
The Nikon D4S has a slightly better low-light AF sensitivity compared to the D4. It can focus accurately in dimly lit conditions down to -4 EV, which is one stop lower than the D4’s -3 EV. This makes the D4S more suitable for shooting in challenging lighting situations.
3. AF Coverage:
- Nikon D4: 51 focus points, covering approximately 91% of the frame
- Nikon D4S: 51 focus points, covering approximately 95% of the frame
Both the Nikon D4 and D4S offer a wide AF coverage with 51 focus points. However, the D4S has a slightly wider coverage, extending to approximately 95% of the frame compared to the D4’s 91%. This means that the D4S provides more flexibility in composing your shots, especially when working with off-center subjects.
4. AF Modes:
- Nikon D4: Single-servo AF (AF-S), Continuous-servo AF (AF-C), Auto-servo AF (AF-A)
- Nikon D4S: Single-servo AF (AF-S), Continuous-servo AF (AF-C), Auto-servo AF (AF-A), Group-area AF, 3D-tracking AF
The Nikon D4S introduces two additional AF modes: Group-area AF and 3D-tracking AF. Group-area AF allows you to select a group of focus points that will work together to track a moving subject, while 3D-tracking AF utilizes color information to maintain focus on a moving subject even if it momentarily leaves the selected focus point.
5. AF Fine-tuning:
- Nikon D4: Yes, with AF Fine-tune feature
- Nikon D4S: Yes, with AF Fine-tune II feature
Both the Nikon D4 and D4S offer AF fine-tuning capabilities, allowing you to adjust the focus accuracy of specific lenses. However, the D4S features an improved AF Fine-tune II system that provides more precise adjustments and a wider range of customization options.
6. AF Speed:
- Nikon D4: Approximately 0.12 seconds
- Nikon D4S: Approximately 0.05 seconds
The Nikon D4S boasts a significantly faster AF acquisition speed compared to the D4. It can lock focus on a subject in approximately 0.05 seconds, while the D4 takes about 0.12 seconds. This makes the D4S ideal for capturing fast-moving subjects or shooting in dynamic situations.
7. AF Performance in Live View:
- Nikon D4: Contrast-detect AF
- Nikon D4S: Hybrid AF (phase-detect and contrast-detect)
The Nikon D4S features a hybrid AF system in Live View mode, which combines phase-detect and contrast-detect AF for faster and more accurate focusing. The D4, on the other hand, relies solely on contrast-detect AF in Live View, which can be slower and less reliable in certain situations.
Which Camera is Right for You?
The choice between the Nikon D4 and D4S ultimately depends on your specific needs and shooting style. If you frequently work in low-light conditions, require faster AF acquisition speed, or want more advanced AF features like Group-area AF and 3D-tracking AF, then the Nikon D4S is the clear winner. However, if you are on a tighter budget or do not need the additional features of the D4S, the Nikon D4 is still a capable camera with excellent AF performance.
Beyond the Autofocus: Other Considerations
While autofocus is a crucial factor to consider when choosing a camera, there are other aspects that you may want to evaluate before making a decision. These include:
- Image Quality: Both cameras offer excellent image quality, with the D4S having a slight edge due to its higher resolution (16.2MP vs. 12.1MP in the D4).
- Video Capabilities: The D4S offers better video capabilities, including 1080p video recording at 60fps and a flatter color profile for more flexibility in post-production.
- Build Quality and Durability: Both cameras are built to withstand harsh conditions, with the D4S having a slightly more robust construction.
- Price: The Nikon D4S is typically priced higher than the D4, reflecting its more advanced features and capabilities.
Basics You Wanted To Know
1. Can I use the same lenses on both the Nikon D4 and D4S?
Yes, both cameras are compatible with the same Nikon F-mount lenses, providing you with a wide range of lens options to choose from.
